Changes in Astigmatism After Ptosis Surgery Measured by Corneal Topography

Summary: A computerized topographic analysis system (EyeSys [EyeSys Technologies, Houston, TX, U.S.A.]) was used to evaluate corneal astigmatic changes (central corneal power and astigmatic axis) after blepharoptosis surgery on 29 eyelids (22 patients). Fifteen nonoperated eyelids of study patients undergoing unilateral ptosis repair were used as controls. All patients were evaluated preoperatively and again 6 weeks after surgery. Fifteen...
