Cataract Surgery

A cataract is a clouding of the eye's naturally clear lens. The lens focuses light rays on the retina, the layer of light-sensing cells lining the back of the eye, to produce a sharp image of what we see. When the lens becomes cloudy, light rays cannot pass through it easily, and vision is blurred.

In cataract surgery, the cloudy lens is removed from the eye through a surgical incision. In most cases, the natural lens is replaced with a permanent intraocular lens (IOL) implant.
