Cataracts

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. Surgery is the only way to remove a cataract. 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 implant.
