See Better Now offers the latest information on vision correction surgery, including LASIK and other procedures, including implantable contact lenses and refractive lens exchange. The implantable contact lens is placed in the eye right behind the iris and lens. For the refractive lens exchange, the natural lens is removed and replaced with a lens designed to improve your vision. The authors are Robert K. Maloney, M.D. and Neda Shamie, M.D., both part of the Maloney-Shamie Vision Institute in Los Angeles.
