Cataract Surgery
From start to finish, these are the major steps you can expect during your cataract surgery.

Astigmatism
An irregular eye surface bends skews light so it can't focus properly.

Light Refraction in the Eye
How the eye bends light determines how well we see.

How Lenses Work
Eyeglasses and contact lenses bend light so it focuses right where it should.

Myopia (Nearsightedness)
The longer shape of the myopic eyeball forces light to converge before it reaches the retina.

Pupil Dilation
Here's how the pupil opens and closes in light and dark conditions, to control how much light comes into the eye.

Hyperopia (Farsightedness)
The shorter shape of the hyperopic eyeball means light focuses beyond the retina.

Bifocal Contacts
Translating lenses stay in place when your eye moves, so your pupil can find the near or distance zone as needed.
