Ilex Eye: Eye Doctors in Waterloo

What is a cataract, and what causes one to form?

A cataract is a clouding of the natural lens inside the eye, just behind the iris centered in the pupil. Contrary to common perception, it is not a ‘film’ on the surface of the eye, although it certainly can cause vision to appear ‘filmy’, among other symptoms.

Cataracts are an inevitable consequence of aging: if you live long enough, you’ll get a cataract. Some general health conditions (like diabetes) and medications (like steroids) can cause cataracts, and longterm exposure to ultraviolet radiation has long been implicated in cataract formation.

Providing an eye care experience

that is second to none
