Total and posterior corneal shape changes after temporal versus nasal clear corneal incision cataract surgery
Aim To compare changes in the shape and astigmatism of the total and posterior cornea between eyes with a nasal clear corneal incision (CCI) and eyes with a temporal CCI in cataract surgery. Methods The left eyes of 100 patients undergoing phacoemulsification were randomly assigned to undergo a 2.4 mm nasal (nasal CCI group) or temporal CCI (temporal CCI group). Corneal astigmatic changes were compared between groups using power vector analysis,and corneal shape changes were compared using videokeratography maps at 2 days, and at 2, 4 and 8weeks postoperatively.
