[Cataract extraction with bifocal lens implantation]

Extracapsular cataract extraction with implantation of an intraocular lens (IOL) is a routine operation in Norway today. With the conventional monofocal IOL, most people require spectacles post-operatively to attain optimal vision. A new principle is the bifocal IOL, which is designed to minimize the patient's need for additional post-operative near vision correction. In this article we present the first results using this bifocal lens. Ten out of 17 patients (18 eyes) had no need of post-operative spectacles. We believe that this lens represents a promising new optical principle, and is an advance in IOL implant technology.
