A Cataract is a clouding of an eye lens that can cause blurred vision, dimmed or yellow vision, making it hard to see. A healthy lens will refract light coming into the eyes to make seeing possible, but in the case of a cataract, this lens gets cloudy/foggy. During a cataract surgery, the natural cloudy lens is removed and a Artificial lens , called an intraocular lens (IOL) is put in its place.
It is a very common procedure and is normally done as an outpatient surgery. It generally requires no hospital stay unless specified by the ophthalmologist doing the procedure.
• Decreased Visual Acuity
• Myopic Shift
• Monocular Diplopia
Cataract is characterized by a painless, progressive decline in vision. Apart from decreasing vision patients with cataract even in the early stages may experience increased glare while driving at night or reading in dim illumination, difficulty in differentiating objects at a distance and the need for frequent change of glasses.
A cataract surgery is considered when the cloudy cataract begins to interfere in a person’s routine. This can include:
• The ability to drive and work
• The ability to read or watch TV
• The ability to complete chores in the house
• The level of independence
A cataract surgery is also considered when the cataract itself comes in the way of treatment of other ailments. This can happen when the doctor in unable to examine the eye due to the cataract.
Based on a diagnosis and level of vision, and answers to questions about vision make it either necessary or not. If the cataract is small and does not interfere with the vision, a surgery is considered unnecessary
Preparing for a cataract surgery can include tests in the run up to the surgery from about before a week. These usually are painless tests to examine the eye, the shape, condition and the size and measure it for the IOL. This test also helps determine the kind of IOL that will be best suited for the person.
Most often than not, there will be restriction of the medicines before the surgery, though you may be specifically given eye drops or medication to help reduce the risk of infection before the surgery. Following the doctor’s orders, with respect to the diet and what is allowed before the surgery is mandatory.
Cataract is detected through a comprehensive eye examination Visual acuity test: The eye chart measures the vision for both distance and near vision. It quantifies the visual loss experienced by the patient.
Dilated eye examination: Drops are instilled in the eyes to widen or dilate the pupils. This allows detection and grading of the cataract. Moreover, the retina or the nerve of the eye is also examined for signs of damage or other eye problems. The effect of the dilating drops lasts for a couple of hours, during which time the patient may experience blurring of vision.
Once the cataract surgery is done, while vision gets progressively better, there is a chance it might be blurry for the first few weeks, which is because the eyes takes time to adjust to the new lens. It is also normal for the eye to feel itchy or dry for a few days after the surgery. It may be recommended for you to wear an eye patch for a few days as well, especially when you sleep.
Some of the other restrictions that may be placed immediately after the surgery can include lifting heavy weights and bending over to pick things off the floor during the recovery period.

During your visit to our My Vision Eye Clinic in Bangalore, first your vision will be checked by trained optometrists. Your pupils will then be dilated and you will be examined by a consultant, who will then discuss the nature of your cataract and your surgery options with you. The consultant will also evaluate your retina or the nerve of your eye. Prior to your cataract operation, you will need to undergo some routine medical and blood tests and an A-scan that will help the doctor to determine the power of the new lens to be implanted in your eye. You can then choose a convenient date for your eye surgery.
After surgery a bandage or shield will be placed over your eye. You can resume normal, moderate activity as soon as you feel up to it. You should wear protective glasses while going out during the first week. You can bathe carefully from below your neck but do not wet the operated eye for 15 days. You are advised to gently clean the eyelids with a piece of cotton boiled in water or a sterilized tissue. There are no diet restrictions following the surgery.
You can return home soon after your cataract operation. A routine postoperative visit the next day is needed.
In some cases, the patient is able to see clearly immediately after the surgery. Although, for most it takes about two to three days.
You may need to wear glasses after the procedure. If a monofocal intraocular lens is implanted, you will require glasses for reading. A multifocal intraocular lens implantation on the other hand will give you freedom from glasses for a majority of your distance, intermediate and near activities.
The implanted intraocular lens is permanent and lasts for the entire lifetime.
Usually both the eyes are not operated on the same day. Once the visual recovery of the first eye is complete, the second eye surgery can be planned.
