Multifocal and bifocal implants.
Removal of cataract with intraocular lens implantation has been a well-accepted treatment for the past two decades.  The development of monofocal intraocular lens technology has represented a significant advance over earlier treatments of cataract and, since the advent of widespread implantation of these lenses, most patients with cataract can achieve good postsurgical vision with the use of bifocal spectacles.
