Surgery to implant Full Focus intraocular lenses is brief and virtually pain-free. Eye drops are used to anesthetize your eyes and mild sedatives are provided to help you relax. Full Focus lens surgery takes approximately 5-10 minutes. You might feel pressure, but typically no pain. The surgery is done with microscopic instruments and is incredibly accurate. A small corneal incision (about 1/12th of an inch wide) is used to implant the lens. Because the cornea does not have blood vessels and the incision is so small, stitches are typically not used and there is rarely any bleeding.
