[The incision in the surgery of cataract and postoperative astigmatism]

There are presented effects of the incision in cataract surgery on postoperative astigmatism. Big changes of astigmatism can be eliminated by applying several basic principles of cataract incisions. Despite the rapid changes in incision technology, these concepts can be applied to all cataract surgery, whether a large or small incision is used, to achieve increased stability and decreased astigmatism. There are also reviewed possibilities of controlling postoperative astigmatism by varying the location and size of the cataract incision.
