PURPOSE: To assess the effect of the type of corneal incision and its closure on astigmatism after cataract extraction.
MATERIAL AND METHODS: 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.
RESULTS: 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.
CONCLUSIONS: 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.
