Journal of Cataract & Refractive Surgery: September 1986 - Volume 12 - Issue 5 - p 519-522 doi: 10.1016/S0886-3350(86)80126-2 Free Metrics Abstract The incidence of posterior capsule opacification after extracapsular cataract extraction was significantly lower in eyes implanted with posterior chamber intraocular lenses than in nonimplanted eyes. The number of loops fixated in the bag was significantly smaller in the eyes that became opacified than in those that did not. These findings suggest that the posterior chamber lens suppresses the two processes that lead to opacification: the development of a ring-shaped opacity at the site of contact between the anterior capsule rim and the posterior capsule and the migration of lens epithelial cells toward the center of the capsule. These suppressive effects were greater when the posterior chamber lens was fixated in the bag. © Williams & Wilkins 1986. All Rights Reserved.
