Cataract

What is Cataract?

Cataract is the clouding of the lens of your eye. As the lens does the work of focusing the images of what we see, a clouded lens leads to a decrease in your vision.

Cataract is a condition in which ones natural crystalline lens turns cloudy or white. This clouding scatters the light passing through the eye, resulting in haze or blurred vision. If left untreated, cataract can eventually lead to blindness. The solution is surgery, where the cataract lens is removed and replaced by an intraocular lens(IOLs).

What to expect from your cataract surgery

Before Your Surgery

Similar to glasses or contact lenses, the new lens will be chosen to meet your vision needs. Your eye will be measured to determine what strength and type of IOL will be best for you. Most patients will be measured with an optical biometer such as the IOL Master.

The Day of Your Surgery

Cataract surgery is generally an outpatient procedure. You will be fully awake, but you will be comfortable and feel minimal discomfort. If any, Local or topical anesthetic will be used.
The cataract is removed using an ultrasonic probe that breaks up and removes the cloudy lens. A new IOL is implanted in its place.

After Your Surgery

Your doctor will provide temporary protective glass or place a cover on your eye and advise when it can be removed. You will need to use drops to prevent infection and promote proper healing.
Depending on the type of lens you receive, you may still need glasses for reading and working on the computer. You should be able to resume most normal activities within a day of your procedure.
