Cataract Surgery

A cataract is essentially a condition in which the lens of the eyes gets clouded creating diminished vision. Cataracts occur because protein builds up in the lens of the eye and it is common among old-aged adults, however, it could occur in young adults and children as well. Cataracts cause the eyes to look foggy, clouded and milky in appearance.

This may result in facing difficulty in driving, reading, or remembering faces. To eliminate the problem of cataract the ophthalmologists suggest to go for cataract surgery.

Cataract surgery by Eyemantra includes the elimination of the natural lens by a simple surgery.

Causes Of Cataract

  • The most common cause of cataract is degenerative differences due to the ageing process. With age, proteins in the natural lens reduce, resulting in a clouded lens called a cataract.
  • Health diseases like diabetes, kidney disease, glaucoma, smoking, eye injuries, infection, and swelling inside the eye.
  • Prolonged use of some medications can also point to cataract development.
  • A cataract may also happen in children due to genetic or metabolic defect or due to infection and trauma.

Causes Of Cataract

  • Blurred vision
  • Difficulty in seeing at night
  • Viewing colors as faded
  • Doubled sensitivity to glare
  • Halos surrounding lights
  • Double vision in the injured eye
  • The requirement for various changes in prescription glasses

What Your Ophthalmologist Looks For?

Your ophthalmologist will suspect cataracts based on your age and medical histories like diabetes issue and your symptoms.


Your doctor can do the diagnosis of cataracts by widening your pupil with medicine and monitoring your eye straight using an ophthalmoscope and a slit lamp. You may also be asked to have a visual acuity test, a test that applies an eye chart to examine the effect of the cataract on your vision.

Expected Duration

Cataracts are long-term difficulties. In most patients, their impact on vision develops with time.


In general, there is currently no way to stop age-related cataracts. Though, people with diabetes may reduce their risk of developing cataracts by fully controlling their blood sugar levels. To help stop infection-related congenital cataracts, women must get checked with their doctors about their demand for rubella immunization before becoming pregnant. Women who are already pregnant should see their obstetricians frequently for fetal care.


Cataract surgery is unusually an emergency. The decision to have surgery depends on the level to which your vision is impaired, balanced by the tiny risk that surgery entails. Although some persons with cataracts view that their vision differs. This happens by using eyeglasses, magnifying lenses, or stronger lighting, the only genuine alternative to cure cataracts are surgery. If cataracts impair both eyes, each eye surgery is scheduled and performed independently. Current surgical choices include Extracapsular cataract extraction and Intracapsular cataract extraction. Once the lens is eliminated, it may be substituted by one of 3 choices IOL implantation, contact lens, and special cataract glasses. Presently, around 90% or more of patients apply an IOL lens.

When To Call Your Doctor

Call your doctor whenever you have found difficulty seeing clearly. If you are older than 40, schedule an eye examination with your doctor every 2 years, even if you have not seen any change in your vision.


Cataract surgery improves the vision of 95 % of patients who have it. Of those patients who have IOL replacements, 90 % have 20/40 vision or better. In a few patients who have had extracapsular surgery, part of the lens capsule ultimately becomes cloudy, causing a condition called an after-cataract. This can be improved with laser surgery, usually as an outpatient.

Who Is At A Risk Of Cataract?

  • Adults above the age of 50 as their eye muscles get weaker
  • Individuals with poor lifestyle habits such as prolonged use of Steroids, Smoking or Alcohol abuse
  • Environmental Factors such as over-exposure to harmful UV rays of the sun.
  • People with diseases auto-immune diseases like Diabetes.
  • People with Eye injuries.
  • People with history eye diseases in the family.
  • People with problems of Obesity.
  • Individuals with Hypertension

One is an eligible candidate for cataract surgery if you are :

    • Undergoing cloudy vision
    • Observing bright colors as faded
    • Experiencing double visions
    • Feeling light sensitivity

CATARACT Surgery Procedure

Cataract surgery is generally performed one eye at a time. Cataract surgery is an outpatient surgery most of the time which means it does not require an overnight stay at the hospital or health care facility. The Cataract eye surgery can be performed via two different procedures.

Traditional Surgery Procedure

    • The scalpel blade is used to create an incision in the cornea by hand.
    • Handheld Instrument is used to open up the sac/capsule holding the eye lens with cataract formation.
    • The Cataract is then fragmented into smaller pieces.
    • Fragmented Lens is then removed using suction.
    • Artificial Lens is implanted to replace the previously natural cloudy lens and it is stitched up

Laser Cataract Surgery Procedure

    • A device named LENSAR is used to break the cataract.
    • Laser (Femtosecond Laser) creates corneal incisions to access the cataract.
    • Cataract is removed using suction.
    • Artificial Lens is implanted into the eye once the cataract is removed.

Zepto Cataract Surgery (STITCH-LESS)


  • Zepto cataract surgery is another type of cataract removal procedure it is a procedure in which a handheld disposable device is used to create a strong, clear-cut, and precise incision in the crystalline lens of the eyes.
  • Zepto surgery is in many ways much better, economical as well as less complicated than the femtosecond laser cataract operation.

Cataract Surgery Facts

  • Early symptoms of cataracts involve blurred vision, glare and stress on eyes while reading.
  • Cataracts will affect most people and become more noticeable age grows.
  • Cataracts can be diagnosed when the doctor observes the eyes with specific viewing instruments.
  • The choice to continue with cataract surgery is essentially based on the amount of problem you have while performing your regular activities.
  • Treatment for cataracts is operational removal of the cataract with implantation of an artificial lens.
  • Several kinds of intraocular lens types can restore vision in varying ways.
  • Cataract surgery is a reliable and efficient way to restore vision with severe complications being unusual.

Types Of Cataracts

Cataracts are among the main causes of loss of vision among adults over the age of 45 and remain the principal cause of blindness across the world. It has been estimated that over 1.3 billion people are living with one form or the other of this disease.

There are various types of cataracts, some of them are:

    • Subcapsular Cataract – Cataracts occur at the back of the eye lens.
    • Nuclear Cataract – Occurs in the central zone of the eye’s lens. (also called the nucleus).
    • Cortical Cataract – White Wedge-like opacity that starts at the edge of the eye lens but slowly works its way to the center (Nucleus).
    • Growing Ages – Nearly half the population by the age of 60 develops cataracts and about 80% of people get a cataract in at least one eye by the age of 70 years.
    • Traumatic Cataract – A direct injury or trauma can cause damage to the eye leading to a cataract. It can be progressive or instantly after a trauma.
    • Metabolic Cataract – Various disorders in body metabolism including autoimmune diseases like diabetes and galactosemia can cause cataracts over time.
    • Secondary Cataract – In several cases, cataract develops as a result of some other primary ocular disease such as chronic eye inflammation or glaucoma.
    • Steroid-induced Cataract – Excess intake of oral steroids or inserting steroid drops in the eye can create cataracts. It is always recommended to ask a doctor before using one.

Catching Cataract Early

Cataracts start interfering with the day-to-day activities of the individual like reading, writing, driving among others hence, it becomes essential to address it as soon as possible. Basically, cataracts make it hard for light to pass through clearly and interferes with smooth vision. However, cataract is not a painful condition and it presents many symptoms before it starts showing drastic effects. Here are some symptoms that you have a cataract. You should immediately consult with an eye doctor if you start noticing any of these symptoms:

    • Night Vision becomes blurry
    • Sensitivity to Bright Lights
    • Pale-yellow/ Clouded Vision
    • Halos at light sources
    •  blurry vision and/or Double Vision

The symptoms of cataract are very subtle and it is also possible that you may not experience all of them at once. However, the cataract symptoms become noticeable slowly as the condition intensifies and it is necessary to consult with an eye care specialist as soon as these symptoms appear even the slightest bit.

Cataract Treatment Option

SURGERY is the only treatment choice for cataract!

Once your lens becomes cloudy or white due to cataract, no medicine can decrease it back to being transparent. Replacement by surgery is the only feasible means to treat it.

Basic Principle of cataract treatment is the elimination of the cloudy lens by surgery and injection of the artificial intraocular lens.

You require to decide and discuss 2 things before going for cataract surgery. The technique of surgery MICS i.e Microincision Cataract Surgery is a simple system of replacement of cloudy lens by artificial lens remaining the same, in MICS the surgeon makes the holes by surgical instrument whereas in robotic cataract surgery the holes are made using computer programing and advanced Femto laser technology. The another thing is type of IOL:- Intra Ocular lens choice depends upon your vision needs and lifestyle like you essentially require near vision.

Type Of Cataract Surgery

There are various technologies and basic techniques for cataract surgery like Phacoemulsification, MICS, Robotic Surgery, Extracapsular cataract surgery and Intracapsular cataract surgery.

Phacoemulsification is the most common form of cataract removal and modern cataract surgery in which the eye’s inner lens is emulsified with an ultrasonic handpiece and extend from the eye. Aspirated fluids are reinstated with watering of balanced salt solution to keep the anterior chamber.

MICS is Micro Incision Cataract Surgery, the outcomes in cataract surgery depend on the size of incision and technology used. The visual results and recovery time are much better linked to conventional treatments as the incision size is even less.

In Robotic Surgery(Bladeless Femto Laser Cataract Surgery) is the epitome of technology for cataract surgery. The treatment utilises computer programming and laser energy to perform the surgery.

The procedure of Extracapsular cataract surgery is usually applied to the person suffering from the most advanced cataract and the lens is very thick to dissolve into fragment or when phacoemulsification is impossible. Extracapsular cataract extraction normally needs an injection of numbing medication around the eye and an eye patch after the operation.

The Intracapsular cataract surgery surgical technique needs an even more open wound than extracapsular surgery, and the surgeon separates the entire lens mutually with the encompassing capsule. This technique needs the IOL to be inserted in a different location, in front of the iris.

Different Types Of IOL Lenses Implanted After Cataract Surgery

As the natural lens plays an important role in focusing light for clear vision, artificial lens implantation at the time of cataract surgery is required as a replacement for the natural lens to generate the best visual outcomes.

Monofocal Lens

Monofocal lens is the most applied lens during implantation. They have similar power in all ranges of the lens and can give high-quality distance vision, normally with only a light pair of spectacles needed for near vision. Monofocal lenses are in the finest focus at only one distance. They do not change preexisting astigmatism, a result of abnormal corneal shape that can change vision at all distances

Toric Lenses

The Toric lenses have more power in 1 specific axis in the lens to improve astigmatism with distance vision. Due to the variation in lens power in diverse areas, the change of astigmatism with a toric lens needs so that the lens be placed in a highly specific configuration. While toric lenses can correct distance vision and astigmatism, the patient still will need corrective lenses for all near tasks, such as account or writing.

Multifocal Intraocular Lens

Multifocal intraocular lens has a variety of sections with another power that enables some individuals to view at all the distances. While assuring, multifocal lenses are not for everyone. They can cause significantly more glare and loss of differences than monofocal or toric lenses.

Aspheric Lens

The Aspheric Lens assures a better quality vision and improved contrast sensitivity. It also provides better night vision and clarity under low light conditions.

What To Expect With Cataract Surgery

Before Surgery

Your surgeon will check your eye to see the proper focusing power for your IOL. Additionally, you will be questioned about any medicines you take. You will also be asked not to take some of these medicines before surgery. You may be prescribed eyedrop medications to begin before surgery. These medications assist in preventing infection and decrease swelling during and after surgery.

During The Surgery

Your ophthalmologist may suggest you not eat a solid meal at least 6 hours before your surgery. The surgery for cataract removal can be done in a clinic, hospital, or outpatient surgery center just a 15-20 minutes procedure. Here is what will follow:

  • Your eye will be numbed with eye drops or with an injection encompassing the eye. You may also be given a medicine that helps you to rest.
  • You will be conscious during surgery. You can see light and movement during the procedure, but you will not recognize what the doctor is doing to your eye.
  • Your surgeon looks with a special microscope by creating tiny incisions i.e cuts, created by laser or a blade near the end of your cornea. The surgeon applies these incisions to enter the lens in your eye. Using very few instruments, he or she will break up the lens with the cataract and eliminate and replace it with your new lens into place.
  • Usually, your surgeon will not require you to stitch the incisions sealed. These self-sealing incisions finally will stop by themselves over time. A shelter will be placed over your eye to preserve it while you recover from surgery.
  • You will rest in a healing area for about 20–30 minutes. Then you will be fit to go home.

Recovery After The Cataract Surgery

The laser cataract surgery is generally a simplistic complication-free procedure which lasts anywhere from 15 minutes to 20 minutes for one eye. However, you can expect to be at the eye clinic for anywhere around 1 and a half hour to two hours. The extra time is taken in preparing for the surgery i.e. dilating your pupils, administering pre-op medication as well as going over the briefs of what to expect during and after the surgery. After the surgery, the surgeon might want to do a post-op evaluation and instructions for recovery after the surgery.

It is advisable not to drive right after the surgery and have someone accompany you for the surgery who can drive you back as well.

In addition to this, medicated eye drops will be administered to you and you will have to use them for a few weeks. Protective eye shields need to be worn as well in addition to the eye drops to ensure the safety of the eyes.

In order for the eyes to fully recover after such an intensive surgical procedure, in the first week it is advisable to avoid:


  • Heavy lifting and strenuous activities (Nothing more than 12kg)
  • Bending and similar intensive exercises that might to put stress on the eyes
  • Advisable to not go to swimming pools, hot tubs and keep eyes closed during showers since water splashed onto the eyes can cause infections.
  • Activities that might expose the eyes to dust or any other infection causing elements.


A good ophthalmologist will inform you well about precautions before as well as after the surgery along with telling you how to take or of the eyes post-recovery period.

Frequently Asked Questions

A cataract is the clouding of the natural lens of the eye. It is the most common cause of vision loss in people of age 40 and is even the leading cause of blindness in the world.

A cloudy lens blocks light from concentrating properly on the back of the eye which points to a range of vision difficulties. These may include:

• Blurred Vision • Sensitivity to Light or Glare • Poor Night Vision • Difficulty driving or using a computer • Double Vision • Colours appear faded or dim

Cataracts normally affect patients over age 55, but, anyone can catch this problem. By the age of 65, 60% of people have formed a cataract and almost everyone over age 75 has at least one cataract. They occur due to the normal ageing process.

A small incision is created in the front surface of the eye with a blade or a laser. A round hole is then cut in the front of the anterior capsule that encircles the eye’s natural lens. Typically the lens is then split into smaller pieces with a laser so it can be more simply separated from the eye. Once the entire lens is eliminated, it is substituted with a clear implant called an intraocular lens (IOL) to recover vision. Today, several processes in cataract surgery can be done with a computer-controlled laser rather of hand-held instruments.

A cataract is diagnosed by your ophthalmologist. For diagnosing cataract ophthalmologists have specific microscopes for examining the eye. A complete eye check includes a complete history, vision testing and record-keeping of the intra-ocular pressure. Drops are inserted to enlarge the pupil. This aids in the visualization of the lens along with the retina and optic nerve at the back of the eye.

All patients will have a primary measurement performed, along with the IOL Master. Depending upon the kind of implant that you prefer, additional tests are done. There is no pain or discomfort connected with any of these tests.

Nothing, as such you have to take care of a few things like inserting the eye drops suggested by your eye doctor several. We ask that you begin eye drops 4 days before eye surgery. These drops will not harm your vision. They are used to prevent and control inflammation, infection and pain. You will maintain these drops for 2 weeks after surgery. You will also be provided with a detailed pre and post-operative instruction sheet before surgery with exact directions on how to take your eye drops.

The cataract procedure itself only takes 10‐20 minutes.

Most normal activities can be continued within a day of surgery. In common, you should begin a normal life but avoid very difficult tasks or contact sports. Do not rub your eye and avoid swimming for 1 week after your surgery. Your ability to drive will depend on how fast your vision restores and the contrast among your eyes after the surgery.

This will depend on the kind of intraocular lenses (IOLs) used for you. The high-level intraocular lenses such as multifocal or accommodating IOLs exceedingly decrease dependency on glasses. In most cases even reading glasses can be avoided.

During cataract surgery, your surgeon will use give you a local anesthetic numbing eye drops to prevent you from experiencing pain throughout your procedure. You will also be provided with a mild sedative to assist you to relax. Depending on the patient and the kind of procedure, extra medication may be used. As the medications wear off, you may feel a scratchy sensation or slight soreness in your eye the first day. Over-the-counter pain relievers can be done to ease discomfort. If important, your doctor will guide stronger pain medication.

With any surgery, you will experience pain, infection, swelling and bleeding. But very few people undergo serious cataract surgery complications. In few cases, side effects from the procedure can be managed with medication procedure. To decrease your risk after cataract surgery, be positive in following the directions your surgeon and describe any unusual symptoms directly.

No, a cataract can’t develop up again as the IOL implantation never requires maintenance and replacement. It very rare in few patients that a cloudy film is formed behind the implant on the lens capsule membrane, normally a few months later after the surgery. This condition is named as secondary cataract.

In 20-30% of cases months later after the surgery, the posterior part of the lens capsule that is left inside the eye while surgery for security reasons becomes cloudy, causing vision to again become blurred this is a secondary cataract. That is also called posterior capsular opacification which normally can be simply treated with a less invasive follow-up procedure called a YAG laser capsulotomy.

Mild cataracts often create little or no vision problems. Your doctor is monitoring your cataract to see if it worsens and more significantly impairs your vision or lifestyle before suggesting surgery. Some cataracts don’t reach the level of surgery.

No, usually in cataract surgery 1 eye surgery is performed at once. The doctor cannot operate both the yes together. This enable the surgeon to judge the outcome of the 1st procedure before operating on the other eye. This evaluation may affect the decisions made for the second surgery, particularly in cases using an accommodative or multifocal lens.

Understanding about Cataract surgery

If one has a cataract, that not always mean that they require surgery. One may not even see any change in their viewing power. Some individuals who have this condition can view everything just fine if they wear prescript glasses.
But as cataracts increase, they can cause more symptoms. However, as the disease grows, or if the central vision gets worse, the only choice for its control is surgery. The effects are blurred vision, glare, and sensitivity to bright lights. When the disease grows, it seems to be painless. Following a decrease in vision which can also appear in a weak quality of life that is in day-to-day activities like driving and working.

This happens usually in elder people of age 50 but nowadays it can be seen in infants and young children too. Its a safe and secure procedure and after the completion of the procedure one is able to see better than before.

Cataract surgery by eyemantra in Delhi involves absorbing out the natural lens after change state inside the eye by a method known as phacoemulsification. After this, an artificial intraocular lens called IOL is placed in its place which returns natural and normal vision

The cataract surgery procedure is conducted under local anaesthesia injected around the eye or topical anaesthesia numbing drops injected into the eye.

Cataracts Surgery Basics

  • In cataract surgery, the lens inside your eye that has become cloudy is eliminated and substituted with an artificial lens called an intraocular lens( IOL) to return clear vision.
  • Multiple advanced cataract procedures include the usage of a high-frequency ultrasound device. That can further break up the cloudy lens into tiny pieces, which are then kindly removed from the eye with suction.
  • The system typically is conducted on an outpatient basis and does not need an overnight stay in a hospital or other care facility.
  • After all remains of the cloudy lens have been removed from your eye, the cataract surgeon injects a clear intraocular lens, placing it safely behind the iris and pupil, in the same location your natural lens occupied. In exceptional cases, an IOL might be located in front of the iris and pupil, but this is less obvious.
  • The surgeon then finishes the cataract removal and IOL implantation procedure by closing the incision in your eye. A stitch may or may not be required. Also, a protective shield is put over the eye to keep it protected in the early stages of your cataract surgery recovery.

Types of cataracts

All of these are cataracts which can be founded in the elderly or kids

  • Nuclear Cataracts
  • Cortical Cataracts
  • Posterior Subcapsular Cataracts
  • Anterior Subcapsular Cataracts
  • Congenital Cataracts
  • Traumatic Cataracts
  • Secondary Cataracts
  • Radiation Cataracts
  • Lamellar or Zonular Cataracts
  • Posterior Polar Cataracts
  • Anterior Polar Cataracts
  • Post-Vitrectomy Cataracts

Out of all of the above, there are the most common cataracts are founded.

Nuclear Sclerotic Cataracts

cataracts surgery

A nuclear cataract is the most basic type of cataract. Starting with a slow hardening and yellowing of the middle part of the lens also recognised as the nucleus. Over time, this hardening and yellowing will increase to the extra layers of the lens.

This type of cataract grows that switches the eye’s strength to focus and close-up vision (for reading or another kind of close work) may temporarily develop. This symptom is indicated to second sight, but the vision develops.

A nuclear sclerotic cataract grows slowly and can take many years for progressive development before it starts to affecting vision.

Cortical Cataracts

cataracts surgery

A cortical cataract forms in the shell layer of the lens identified as the cortex and slowly increases its “spokes” from the exterior of the lens to the centre. These gaps can cause the light that enters the eye to scatter, building difficulties with blurred vision, glare, contrast and depth perception. People with diabetes are at risk of evolving cortical cataracts.

Posterior Subcapsular Cataracts

cataracts surgery

This type of cataract starts with affecting one’s reading and night vision. A small opaque or cloudy area on the back surface of the lens is called subcapsular. This happens because it forms below the lens capsule which is a small sac or membrane that encircles the lens and retains it in position.

Who will face this problem in future?

  • A person who have age more than 60 years
  • People with prolonged use of steroids
  • Overexposure to ultraviolet rays
  • People suffering from Diabetes
  • Injuries related to eye

Why One should go for cataracts Surgery?

Reasons why a person needs cataract surgery are :

  • One may be facing a dim, blurred, or yellow vision or may also possess double vision when you look at things through the eye with the cataract. These difficulties can make it tough to read, work on a computer, and do anything else that asks for clear eyesight. This is why we one needs cataracts surgery.
  • One may have poor night vision and discover it more difficult to drive when it’s dark. Persons with advanced cataracts can even fail the eyesight part of a driver’s test.
  • Cataracts can make a person more sensitive to glare from the sun. One may see a halo nearby bright lights. It also makes it more difficult to play a few sports, like golf.

If one has any of these symptoms, surgery can help.

Sometimes one may require to get surgery even if your cataract doesn’t trouble you. Your doctor may recommend it if the cataract makes it difficult for one to make a clear picture of the back of their eye while an eye exam.

  • Undergoing cloudy vision
  • Observing bright colours as faded
  • Experiencing double visions
  • Feeling light sensitivity
  • Undergoing poor night vision
  • No Pregnancy and nursing

  • Not undergoing dry eyes activity

How will one get to know that they need cataracts surgery?

After a precise and complete eye evaluation, doctors will discuss the diagnosis of cataract and your best-corrected visual acuity (your vision with glasses). They will help you to decide for yourself, with test lenses, if you are satisfied with this vision by wearing glasses in your day to day life or not.

In case, if you are not satisfied, in the absence of any eye disease that may harm your vision, the surgeon will talk with you the chance of cataract surgery in Delhi, and its convenient procedure.

  2. Stop using specific medications-  Your doctor may recommend you to briefly stop taking any medication that could raise your risk of bleeding throughout the procedure. Let your doctor know if you take any medications for prostate difficulties, as some of these drugs can interfere with cataract surgery.
  3. Use eye drops to decrease infection risk-Antibiotic eyedrops may be suggested to use for 1-2 days before surgery.
  4. No Food -You may be directed not to eat or drink anything 12 hours before the cataract procedure.
  5. Plan for your recovery- Usually, you can go home on the day as your surgery gets completed. But you won’t be able to do any outdoor activities.

Types of cataracts surgery

  • Phacoemulsification (phaco)

cataract surgery

Phacoemulsification is a new cataract surgery in which the eye’s internal lens is fuse with an ultrasonic handpiece and aspirated from the eye. Aspirated fluids are substituted with irrigation of balanced salt solution to support the anterior chamber.

During phaco surgery, a surgeon makes a tiny incision at the tip of the cornea and then performs an opening in the membrane that encloses the lens. A little ultrasonic probe is then inserted, breaking up the cloudy lens into small fragments. The instrument vibrates at ultrasonic speed to cut and nearly dissolve the lens material into little fragments. The fragments are then suctioned out of the capsule by an attachment on the probe tip.

After the lens particles are eliminated, an intraocular lens implant, generally referred to as an IOL, is implanted and placed into the lenses natural capsule. It is injected through the tiny corneal incision by a hollowed-out tube. Once the lens is forced by, it opens and is positioned in place.

  • Femtosecond Cataracts Surgery

Femtosecond surgery is a different option possible for your doctor to use as cataract surgery. It is an FDA approved, a computer-guided laser that is processed by the surgeon. This device can help the surgeon in the performance of some of the steps included in the elimination of a cataract. It can also be used in procedures conducted to correct astigmatism.

  • ​Zepto cataracts or Zepto Capsulotomy Device for Cataract Surgery

cataracts surgery

Zepto Capsulotomy Device for cataract surgery” is significantly lower than femtosecond cataract surgery, and practices a handheld disposable device to create a particular and precise capsulotomy. This seems in some logistical challenges and decreases overall surgical time in comparison to Femtosecond laser-assisted cataract surgery. Plus, Femtosecond laser cannot be practised in patients with corneal opacities or small pupils, while the Zepto capsulotomy device can be. The device also offers the surgery more reliable and more anticipated.

  • Manual small incision cataract surgery (MSICS)

cataracts surgery

This technique is an unfolding of ECCE where the whole lens is sent out of the eye by a self-sealing scleral tunnel wound. A properly formed scleral tunnel is watertight and does not need suturing. The “small” in the title indicates to the wound being comparatively smaller than an ECCE, although it is still considerably larger than a phaco wound. Head-to-head trials of MSICS vs phaco in dense cataracts have seen no variation in results, but lower performing time and significantly lower costs with MSICS.

  • Extracapsular cataract extraction (ECCE)

Extracapsular cataract extraction includes the removal of almost the whole natural lens. While the elastic lens capsule that is posterior capsule is left unimpaired to enable implantation of an intraocular lens. It involves the manual expression of the lens by a large incision created in the cornea or sclera. Its is usually 10–12 mm.

Although it requires a larger incision and the use of stitches, the traditional method may be designated for patients with very hard cataracts or other situations in which phacoemulsification is questionable.

  • Intracapsular cataract extraction (ICCE)

It involves the removal of the lens and the enclosing lens capsule in one section. The procedure has a comparatively high rate of difficulties due to the large incision required and pressure placed on the vitreous body. It has consequently been largely replaced and is usually done in countries where working microscopes and advanced-technology equipment are easily accessible. After lens removal, an artificial plastic lens an intraocular lens implant can be set in either the anterior chamber or sutured into the sulcus.

Side Effects of cataracts surgery

Side effects are limited from cataract surgery, but few things that can occur.

  • Swelling or Eye infection
  • The feeling of pressure into your eye
  • Bleeding
  • Detachment of Retinal
  • Loosening of the latest implant
  • Fluid accretion in your eye
  • Drooping of eyelid

Cataract Surgery Costs

Cataract surgery expenses are usually covered by Medicare if you are Medicare available. Private insurance usually includes cataract surgery as well. The cost of cataract surgery depends upon the age of the person, the intraocular lens was taken also the earlier history of eye procedures. Depending upon these parts, cataract surgery cost can vary from Rs to Rs. The specific price can be decided by visiting our clinic eye mantra. Also, get engage with our cataract surgeons in Delhi who will discover the precise condition of the eyes and can provide you with an exact cost calculation.

What you can expect

Pre- preparation for cataract surgery

Almost everyone who has cataract surgery will be given an artificial lens IOL. These lenses improve your vision by concentrating light on the back of your eye. You won’t be able to view or sense the lens. It needs no care and stays a permanent part of your eye. A variation of IOLs with various features are available. Before surgery, you and your eye doctor will explain which type of IOL can work best for you and your healthy life. Cost may also be a part, as insurance companies may not compensate for all types of lenses.


  • IOLs are made of plastic, acrylic or silicone.
  • Many of the IOLs block ultraviolet light.
  • Some IOLs are rigid plastic and implanted by an incision that needs several stitches (sutures) to close.
  • Many IOLs are adjustable, providing a shorter incision that needs few or no stitches.

The surgeon gives this type of lens and injects it into the empty capsule where the natural lens applied to be. Once inside the eye, the collapsed IOL unfolds, filling the empty capsule.

Many  types of lenses easily available can be seen as :

  • Fixed-focus mono-focal

This type of lens has a particular focus power for distance vision. Reading will usually need the wear of reading glasses.

  • Accommodating-focus mono-focal

Although these lenses must have a particular focusing power, they can react to eye muscle movements and change focus on to near or far objects.

  • Multifocal

These lenses are related to glasses with bifocal or progressive lenses. Several areas of the lens have various focusing powers, providing near, medium and distant vision.

  • Astigmatism correction (toric).

If you have particular astigmatism, a toric lens can assist in correcting your vision.

Share the advantages and risks factors of the various kind of IOL with your eye surgeon to know what’s good for you.

During cataract surgery

Cataract surgery, normally an outpatient procedure, takes 1 hour or less to be conducted.

  • First, your doctor will put eye drops in your eye to increase your pupil. You’ll receive local anaesthetics to anaesthetize the area. Then you may be provided with a medication that helps you to relax. If you’re provided with a sedative it will make you remain awake but tired during surgery.
  • During cataract surgery, the clouded lens is eliminated. A clear artificial lens is normally implanted. In some cases, a cataract may be eliminated without implanting an artificial lens. with different surgical methods.

Surgical methods used to eliminate cataracts include:

  1. Applying an ultrasound probe to break up the lens for removal. During a procedure called phacoemulsification, your surgeon creates a tiny incision in the front of your eye that is cornea. Further inserts a needle-thin probe into the lens element where the cataract has developed. Your surgeon then uses the probe, which sends ultrasound waves, to break up the cataract and suction out the fragments. The very back of your lens the lens capsule is left unimpaired to help as a place for the artificial lens to rest. Stitches may or may not be applied to join the tiny incision in your cornea after the procedure.
  2. Using high-level laser technology to eliminate the cloudy lens. In laser-assisted cataract surgery, the surgeon uses a laser to perform all incisions and soften the cataract for elimination.
  3. Creating an incision in the eye and eliminating the lens in one piece. A less commonly used method called extracapsular cataract extraction. This needs a longer incision than that used for phacoemulsification. By this larger incision, your surgeon applies surgical tools to eliminate the front capsule of the lens and the cloudy portion of your lens holding the cataract. This procedure may be done if you have certain eye complexities.

Once the cataract has been eliminated by phacoemulsification or extracapsular extraction, the artificial lens is implanted into the empty lens capsule.

After cataract surgery

  • After cataract surgery, expectations are a vision to begin improving within some days. Your vision may be blurry at once but after that, it begins eye with healing and improves.
  • Colours may appear brighter after surgery because you are seeing through a new and clear lens.
  • Keep visiting your eye doctor in a day or two after your surgery, the following week, and then repeat after about a month to observe healing.
  • It’s common to sense itching and moderate discomfort for a couple of days after surgery. Avoid rubbing or straining on your eye.
  • Visit your doctor just after  you experience any of the following:
  1. Loss of vision
  2. Pain that continues despite the taking a course of medicines
  3. Raised eye redness
  4. Light flashes or many new spots (floaters) in front of your eye

Many people require glasses for some of the time just after cataract surgery.

If you have cataracts in both eyes, your doctor normally schedules the 2nd  surgery after the first eye has healed.

Results of the surgery

Cataract surgery strongly recovers vision in the majority of a person who has gone through the procedure.

People who had cataract surgery may get a secondary cataract. In the medical terms, this complexity is named as posterior capsule opacification (PCO). This occurs when the back of the lens capsule that is the part of the lens that wasn’t eliminated during surgery and that presently supports the lens implant that becomes cloudy and impairs your vision.

PCO is operated with a painless 5 minutes outpatient method called YAG that is yttrium-aluminium-garnet the laser capsulotomy. In YAG laser capsulotomy, is a laser beam is applied to make a little opening in the clouded capsule to give a clear path by the way light can pass.

After the procedure, stay in the doctor’s office to make sure your eye stress doesn’t rise. Other difficulties are rare but can involve raised eye pressure and retinal detachment.

Cataract Surgery Recovery

  • Time after surgery the days of the week’s situation.
  • You will have to apply eye drops after surgery. Make sure to comprehend your doctor’s medicinal courses for using these drops.
  • Avoid using soap or water directly in the eye.
  • Do not rub or press on your eye. Your ophthalmologist may suggest you wear eyeglasses or some other shield to protect your eye.
  • One will be asked to wear a protective eye shield while sleeping.
  • Your ophthalmologist will talk with regarding how active you can be soon after surgery. He or she will tell you when you can reliably exercise, drive or do different activities again.

Laser Cataract Surgery

cataracts surgery

Recently, many femtosecond lasers similar to the lasers used to generate the corneal flap in all-laser LASIK — have been recognised by the FDA.

  • These lasers have obtained approval for the following steps in cataract surgery, decreasing the demand for surgical blades and other hand-held tools:
  • Producing corneal incisions to enable the surgeon access to the lens
  • Separating the anterior capsule of the lens
  • Fragmenting the cataract so less phaco energy is needed to break it up and eliminate it.
  • Formulating peripheral corneal incisions to decrease astigmatism when required.
  • Lasers can develop accuracy during several steps of cataract surgery, they may not significantly advance cataract surgery protection, recovery time and visual results in every case.

Frequently Asked questions

1) How much time will be taken to heal from cataract surgery?

Ans. It will take about 6 – 10 weeks to totally to heal from cataract surgery.

2) Is surgery the single method to operate cataracts?

Ans. Our optometrist can guide changes in your eyewear that will assist one to see more precisely until the surgery is required. When eyewear no longer gives adequate eyesight, surgery is the only recommended that means completely treating cataracts.

3) Is cataract surgery safe for thinking of future aspects?

Ans. Yes, the Cataract surgery is commonly recommended as its a permanent and never takes much time to get operated. Also, the healing time is quick and gives you a clear and new vision.

4) Is laser cataract surgery beneficial?

Ans. Yes, it is beneficial as :

  • A deeply customized treatment using high-level 3D imaging
  • An extra specific treatment
  • Gentler and more comfortable cataract elimination with less ultrasound energy
  • More choices for astigmatism correction

5) What is a do you mean by secondary cataract?

Ans. This secondary cataract also called posterior capsular opacification. Normally can be simply treated with a less invasive follow-up method called a YAG laser capsulotomy.

In this case, a just few months or years of cataract surgery, the posterior portion of the lens capsule that is in the left side inside the eye is facing problems. It happens during surgery for security reasons becomes hazy, creating a vision to repeatedly become blurred.


Cataracts have become nearly normal for people to be diagnosed after the age of 50 years. In this situation, clouding occurs in the natural lenses of the eyes, which lie back the iris and the pupil.

A cataract may happen as a result of prior eye surgery such as ICL. Also, because of ageing, genetic disease, diabetes, illness to ultraviolet rays or radiation, or eye injury which alters the tissue of the Laser Cataract Surgeryeye lens. When a cataract happens, the natural lens of the eyes become hazy due to protein denaturation. This blocks light from passing through the lens, clouding the vision.

Cataracts surgery is a recommended procedure that holds around 30 to 45 minutes.
