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.

Corneal Transplantation - The cornea is the clear front layer of the eye. It serves to focus light and as a barrier for the eye. Certain conditions can give rise to poor clarity or curvature, requiring corneal transplantation. This is performed using human donor tissue. Corneal transplantation is the most common and successful form of organ transplantation.
