The Impact of Surgical Procedures on Postoperative Outcomes in Cataract Phacoemulsification and Analysis of Related Factors
Sponsor: Zhongshan Ophthalmic Center, Sun Yat-sen University
Summary
The goal of this observational study is to evaluate the location of phacoemulsification tip measured by intraoperative OCT during cataract surgeries and its impact on early postoperative changes of cornea and visual acuity. The main question it aims to answer is: In patients with age-related cataracts undergoing phacoemulsification, does the location (supracapsular, iris-lens diaphragm, or endocapsular) of the phaco tip affect postoperative corneal changes and visual acuity at early postoperative stage? Eyes having phacoemulsification for cataracts will receive intraoperative OCT imaging to evaluate the location of the phaco tip during surgery, and corneal changes and visual acuity will be measured postoperatively.
