Comparison of toric IOL implantation and opposite clear corneal incision during cataract surgery to correct corneal astigmatism

There are different methods to correct corneal astigmatism during cataract surgery. One method is to implant a toric IOL, another method is to set an opposite clear corneal incision (OCCI). Purpose of this study is to compare the astigmatism reducing effect of a toric IOL with that of opposite clear corneal incision surgery combined with a spherical standard IOL. First findings show that OCCI as well as toric IOL implantation effectively correct low preoperative corneal astigmatism.
