title: Astigmatic decay following small incision, self-sealing cataract surgery.
abstract: A series of 22 consecutive patients had phacoemulsification using a small (3.5 to 4.0 mm), self-sealing incision. Preoperative keratometric analysis was performed using the EyeSys photokeratoscope. Results of this analysis were compared with keratometric data obtained at one week and at one month postoperatively. These comparisons were evaluated for surgery-induced cylinder and astigmatic decay at the 3, 5, and 7 mm corneal zones. At one week postoperatively, there was only mild against-the-rule change in cylinder at each corneal zone, and these changes showed minimal decay at the one month follow-up visit.
