What is a Cataract?

With age, the natural lens of your eye slowly becomes cloudy. This is called a cataract. It is a normal process and starts when you are very young. Your lens is like an onion, gradually getting thicker and cloudier with age. Some people’s lenses become cloudy more quickly and can require surgery as early as in their late 30′s or 40′s, while others may not need surgery until they are in their 70′s, 80′s or even 90′s.

Overview of the Eye

Think of your eye as a camera. In order for a camera to function, you need a lens to focus the light onto the film. Your natural lens, which is located inside your eye, is like the lens of a camera. It focuses the light on the film of your eye, which is called the retina.

Lens Options

Dr. Patodia is pleased to offer five lens options. He will sit down with you, one on one, and discuss your best choice. See the different lens options available to you.

Pre-Operative Measurements (Before Surgery)

Corneal Map

Corneal topography is a computerized, three dimensional imaging process that provides detailed information about the surface contour of the cornea.

IOL Master

A non-contact optical device that measures the distance from the corneal vertex to the retinal pigment epithelium by partial coherence interferometry, the IOL Master is consistently accurate to within ±0.02 mm or better.

Immersion and A Constant

The Immersion measures the length of the eye using an ultrasound. This measurement is standard and is provided for all lens types.


Post-Operative Care (After Surgery)


After surgery, some patients notice a clouding or blurring of vision in the surgical eye. This laser creates an opening in the capsular bag to allow for return of clarity of vision. The procedure takes only minutes and is painless.
