title: [Intraoperatively-induced astigmatism after "small incision cataract extraction". An analysis of 4.0 mm, 5.0 mm and 6.5 mm incisions].
abstract: Surgically induced astigmatism in three series of cataract surgical procedures were compared. The three series comprised 120 eyes having phacoemulsification and implantation of: a) a foldable silicon lens through a 4.0 mm incision (32 eyes), b) a 5.0 mm PMMA lens through a 5.0 mm incision (48 eyes) and c) a 6.5 mm diameter PMMA lens through a 6.5 mm incision (40 eyes). There were no significant differences in surgically induced cylinder between the three groups after one month or 6 months postoperatively. No differences between these three groups with respect to visual rehabilitation were seen. We concluded that small diameter PMMA implants inserted through a 5.0 mm or 6.5 mm incision minimized surgically induced cylinder in a way comparable to the use of foldable silicone implants inserted through a 4.0 mm incision.
