What is Cataract Surgery?

A cataract is a dense and cloudy area that forms on the lens of the eye. When proteins in the eye form clumps preventing the lens from sending any clear image to the retina, cataract is formed. The function of the retina is to convert light into signals. It then sends the signals to the optic nerve, which then carries them to the brain. Cataract doesn't develop suddenly; it forms slowly and gradually starts interfering with everyday life of the person. Cataract can form in one or both the eyes, but usually, they don't form at the same time. Cataracts are commonly witnessed in older people than younger ones.

Your ophthalmologist will assess your eye and check the vision clarity. Your doctor might ask you to go through an eye chart test to check your vision from a distance. The doctor might also check your eye pressure. This is known as the tonometry test. To check your pupils, the doctor might put drops in your eyes which will make the pupils bigger. This is done to check the optic nerve and to confirm if there is any damage to the retina of the eye. The ophthalmologist might ask you to do a few more tests to check your eye's sensitivity to glare and perception of colors.


MICS - Microincision cataract surgery (MICS) is an approach to remove cataract through incision less than 1.8 mm. The purpose of the surgery is to improve the outcome of the surgery. MICS has been relied on to be a minimally traumatic surgery that offers better postoperative outcomes. In this sophisticated cataract surgery, a high degree of surgical precision and innovation is used. Advantages of MICS include:

  • Smaller incision
  • Decreased chances of surgically induced astigmatism
  • Faster recovery of vision
  • Faster healing

FLACS - Femtosecond laser assisted cataract surgery (FLACS) is a recent development in the field of cataract surgery. FLACS carry lesser risks compared to non-FLACS small incision phacoemulsification cataract surgery. Compared to manual techniques, FLACS can offer a greater level of precision and repeatability for certain tissue planes. Phacoemulsification, or phaco - In this process, a small incision is made on the side of the cornea. The ophthalmologist will then insert a tiny probe into the eye. The device will emit ultrasound waves to soften and break the lens. The broken parts are then removed by suction.

Facts on Cataract

  • A cataract is a clouding of the eye lens.
  • Cataracts develop when proteins in the lens clump together.
  • More than half of the Indians have cataracts by the time they turn 70.
  • Major factors leading to cataracts are - exposure to sun, obesity, smoking, high myopia, eye injury, and family history.
  • There are three types of cataracts - subcapsular, nuclear, and cortical.
  • Cataract is considered to be the most common eye problem faced by people as they age.
  • Cataract surgery is considered to be one of the most perfected surgeries in the world.

What are the reasons behind cataract?

The lens of the eye works similar to that of a camera lens. It focuses light on the retina to help a person have clear vision. The eye lens is mostly made of protein and water. The protein in the eye helps pass light through it. But as people age, the proteins in the eye may clump together and gradually form a cloudy area on the eye lens. This is known as cataract. Over time, the cataract may increase, become large and make it harder for the person to see anything.

Types of cataract:

There are two types of cataract:

  • Subcapsular cataract - It occurs at the back of the lens. People with high diabetes or high doses of steroid medications are at a greater risk of developing this form of cataract.
  • Nuclear cataract - This form of cataracts develop deep in the central zone of the lens. Nuclear cataract usually forms with aging.
  • Cortical cataract - In this form of cataract, white, wedge like opacities form in the periphery of the lens. This form of cataract occurs in the cortex of the lens.

Preventions of cataract:

The old saying, prevention is better than cure, is as valid for cataract as for any other disease. Here are a few significant ways to prevent the loss of vision due to cataract:

  • Modify your daily diet
  • Stop smoking
  • Protection from ultraviolet radiation
  • Control your blood sugar
  • Avoid trauma
  • Cut down on unnecessary use of steroids
  • Regular eye check up
