Abstract
In a review of 18,470 consecutive cases from 1992 to 1999, the overall incidence of posterior capsular (PC) tear was 83, resulting in an incidence of 0.45%. Of these cases, the incidence of vitrectomy was 22%. This incidence compares favorably with reports by other authors. I 1 Fishkind W.J.

Interestingly, Gimbel’s yearly incidence of PC tears is remarkably consistent. This would indicate that, try as we may, we cannot eliminate tears of the PC during cataract surgery.
