• Status: Unknown
• Phase: N/A
• Study type: Interventional
• Enrollment: 294 (estimated)
• Sponsor: Zhongshan Ophthalmic Center, Sun Yat-sen University · Academic / Other

Summary

Objective and Principle: To evaluate whether enlarging the incision can reduce corneal complications associated with phacoemulsification with regular 2.2 mm incision. The aim of this study: To evaluate whether the technique of enlarging internal incision could reduce the incidence of descemet membrane detachment after 2.2 mm incision phacoemulsification. Secondary outcome: To evaluate whether the technique of enlarged internal incision can reduce other corneal complications such as corneal edema and astigmatism after 2.2 mm incision phacoemulsification. Study Design: A prospective randomized controlled study
