Effect of Upper Eyelid Surgeries on Corneal Topography, Corneal High-order Aberration, Corneal Biomechanical Properties, and Corneal Epithelial Thickness
In Brief
An observational study evaluating levator muscle resection surgery, Müller's muscle-conjuctival resection surgery, and 1 other intervention for Eyelid Diseases and Ptosis, Eyelid. Completed, enrolled 13 participants across 1 site.
Detailed Summary
The goal of this prospective observational study is to learn about the impact of conventional eyelid correction surgery on the eye's health and function in ptosis and eyelid retraction patient. The main questions it aims to answer are: • 1. Changes in corneal topography, higher-order corneal aberrations, corneal biomechanical characteristics, and corneal epithelial thickness before and after the surgery 2. Influence of corneal refraction examinations , vision change, and tear film function after the surgery Fifty participants will undergo conventional eyelid correction surgery by the same ophthalmologist (YH Wei) and non-invasive examinations before and after the surgery. The patient will be separate to 2 groups, including 30 with correction for ptosis and 20 with correction for eyelid retraction. The research will collect information of the operated eye and fellow eye, and the data will be compared between operated and fellow eye and with the other group.
