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.
囊外手术是一种理想的白内障手术类型，与晶状体植入相结合时，晶状体的稳定性和固定性会大大增强。然而，可以预期会出现一些并发症。囊外手术的主要问题是后囊膜混浊。这是由于晶状体生发纤维的再生。为了防止这种情况，即使在晶状体植入时，也建议彻底清除皮质晶状体物质。然而，这需要特殊的晶状体，这种晶状体具有额外的虹膜固定装置。
