Purpose:
To present the means and technique used in our Department for prevention and management of posterior capsule rupture during planned extracapsular cataract extraction.
Methods:
Prospective analysis of 550 extracapsular cataract operations from October 1993 to March 1994. Our technique (a slight modification of Blumenthal's technique) included a triplanar watertight small scleral incision, a relatively large continuous curvilinear capsulorhexis, or can-opener capsulotomy, nucleus hydrodissection and hydroexpression, use of an anterior chamber maintainer and residual cortex removal through a 10 o'clock side-port corneal incision.
Results:
Best corrected postoperative visual acuity ranged from 7-10/10 in 93.45% of our cases. Posterior capsule rupture with or without vitreous loss occurred in 1.63% and 2.72% of the cases, respectively. These rates are much lower than those, observed, when we used the sclerocorneal incision and nucleus extraction with external pressure.
Conclusions:
The combination of a triplanar watertight small scleral incision. A relatively large continuous curvilinear capsulorhexis, an anterior chamber maintainer and residual cortex aspiration through the 10 o'clock side-port corneal incision greatly reduced the posterior capsule rupture rate.
