To assess the effect of the type of corneal incision and its closure on astigmatism after cataract extraction. Induced astigmatism was evaluated in 94 eyes after cataract extraction with IOL implantation 7 days, 1 month, 3 months, 6 months and 12 months after operation. 3 groups: were compared I--after extracapsular extraction with corneo-scleral incision (10 h-2 h) and continuous cross-like suture, II--after phacoemulsifications with scleral tunnel incision (3.3 mm) without suture. The highest induced astigmatism was observed 7 days after surgery in patients with the longest corneo-scleral incision with suture (group I). Induced astigmatism gradually decreased in time. In group after phacoemulsification especially with no suture low astigmatism with prompt stabilization was observed. The length and type of closure of the incision have an essential effect on induced astigmatism. Small incision, especially without suture induces minimal early postoperative astigmatism which remains stabile.
