What this Trial Is About

This observational study investigates the effects of Levator Resection combined with Fascial Sheath Suspension surgery on patients with congenital ptosis. It aims to evaluate whether this combined surgery improves best-corrected visual acuity, stereopsis, and other visual function measures within six months after the operation. The study also explores whether patients experience an improvement in quality of life during the same period. Patients scheduled for this combined surgery as part of their regular medical care will be followed prospectively. They will undergo standardized ophthalmological examinations and complete a quality of life questionnaire before surgery and again at 1, 3, and 6 months after the procedure. This design allows researchers to observe changes over time in both visual function and psychological wellbeing. Participants will be involved in evaluations that include vision tests and quality of life assessments at multiple time points spanning from before surgery to six months after. The primary outcome measured is stereoacuity, assessed from enrollment through the six-month post-surgery period. The study is led by the Zhongshan Ophthalmic Center at Sun Yat-sen University and includes patients aged 3 to 60 years with congenital ptosis.
