Cataract Surgery

Cataract is clouding of the natural lens within the eye. When we are younger the lens inside our eyes are clear and allows light rays to enter our eyes.


Cornea Surgery

When a cornea becomes swollen, scarred and warped, light cannot pass through the cornea to reach the retina and then vision becomes decreased or lost depending on the severity of the corneal opacity.
