[Rupture of the posterior capsule and the implantation of an artificial lens].
OBJECTIVE
Study of the incidence and side effects of the posterior capsule ruptures in a clinical trial.


METHODS
Retrospective study of cases with posterior capsule ruptures encountered in a series of 162 with elective extracapsular extraction and posterior chamber lens implantation.


RESULTS
Intraoperative posterior capsule ruptures occurred in 16 cases (10.12%), 4 cases without vitreous loss and 12 cases with vitreous loss. 12 cases were managed by simple posterior chamber lens implantation of with scleral or iris suture; in 4 cases we preferred anterior chamber implants with flexible haptic: average postoperative visual acuity was 0.74 in the group with intact posterior capsule and 0.45 in the group with posterior capsule ruptures; average postoperative visual acuity was 2 lines higher in the group with posterior capsule ruptures without vitreous loss as compared with the group with posterior capsule ruptures and vitreous loss; postoperative complications were more frequent in the group with posterior capsule ruptures; intraocular lens descentrations were more frequent and more serious in the group with posterior capsule ruptures.


CONCLUSIONS
Posterior capsule ruptures negatively affects the late functional results due to higher rate of major complications and to difficulties in artificial lens implantation.
