[The impact of incisional dimensions on the surgically induced astigmatism].

Purpose: The study reveals the incision's dimension impact on the the values of the postoperative induced astigmatism after cataract phacoemulsification surgery.

Method: The study involved 648 patients who have suffered cataract surgery by phacoemulsification.

Results: The postoperative induced astigmatism has lower values as the incision's dimension is lower The astigmatism takes place after cataracts with hard nucleus.

Conclusions: The microincisions used in cataract surgery allow the obtaining of lower values of the postoperative induced astigmatism. The nucleus's hardness has an influence over the values of the postoperative induced astigmatism.
