What We Do

The Comprehensive Ophthalmology Unit cares for a broad range of eye conditions for all ages with a primary surgical interest in cataracts.

A cataract is a clouding that develops over the lens of the eye and can affect part or all of a person's vision.  Most cataracts are caused by age-related changes and a significant number of people over 60 encounter trouble with them. But cataracts can also be caused by trauma, eye inflammation, steroid usage and complications of diabetes.


What are the symptoms​?

The common symptoms of cataracts include blurry vision, glare, and increasing short-sightedness.

The most common treatment for cataracts is surgery. The ophthalmologist removes the damaged lens and replaces it with an artificial lens to restore your vision.

An ophthalmologist can diagnose cataracts by giving you an eye test (checking to see, for instance, if you can read the smallest letters on the standard chart), and they may also check eye movements and responses, as well as measure the pressure inside the eyes.
