Recent advances in cataract surgery.

Cataract surgery has undergone profound changes in the past ten to twenty years. Not only are these changes evident in the technique and methods of extraction, but it has become critical for the well-versed ophthalmic surgeon to be concerned with the optical correction of aphakia. New instruments, highly refined microscopes, and better diagnostic techniques have all contributed to significant improvement in the result of the procedure. Sophisticated surgical instruments are now available for highly trained surgeons. Intraocular lens implantation (pseudophakia) has introduced one of the greatest controversies in ophthalmic surgery. The advantages and disadvantages of this process are set forth.
