A: In conventional (traditional) cataract surgery, the eye surgeon creates a small incision in the cornea’s side using a metal or diamond scalpel blade. Ultrasound energy breaks up the lens’ cloudy centre. Then, the broken-up pieces of lens are suctioned out of the eye. An artificial intraocular lens replaces the cloudy natural lens. After surgery, a special liquid and self-seal fill the corneal incision’s side walls. Most commonly, stitches are unnecessary.
