Abstract

The cataract surgery with viscoelastic agent was performed in forty eyes of twenty rabbits which were divided into two groups, one group with intact posterior capsule and the other group with ruptured posterior capsule of the lens, to evaluate the effect of viscoelastic agents on IOP according to presence of the intact posterior capsule of the lens after cataract surgery. The viscoelastics used were Healon in control group, and Healon, Viscoat and Occucoat in experimental group. We checked the IOP during one month. Peak IOP after surgery and the time from surgery to the peak IOP showed no difference between two groups. In experimental group, there was no difference in the change of postoperative IOP according to the kind of viscoelastics. Results suggest that the rupture of posterior capsule of the lens plays a role in delayed excretion of the viscoelastics, and the postoperative elevation of IOP was not different regardless of the physical difference of Viscoelastics.
