Extracapsular surgery and lens implantation.

Extracapsular surgery is an ideal type of cataract surgery in combination with lens implantation insofar as stability and fixation of the lens is greatly enhanced. However, a number of complications can be expected. The main probelms of extracapsular surgery is posterior capsule opacification. This is due to regeneration of germinal lens fibers. To prevent this a complete removal of cortical lens matter is advisable, even in lens implantation. This however requires special lenses, which have additional iris fixation.
