NCT05750251

Brief 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. 1.Changes in corneal topography, higher-order corneal aberrations, corneal biomechanical characteristics, and corneal epithelial thickness before and after the surgery
  2. 2.Influence of corneal refraction examinations , vision change, and tear film function after the surgery

Outcome Measures

Primary Outcomes (14)

  • Change from best corrected visual acuity at 3 months after the surgery

    Assess best corrected visual acuity by qualified optometrists, with Landolt C chart-based examination Record as decimal visual acuity

    Baseline, Month 1, Month 3

  • Change from intraocular pressure at 3 months after the surgery

    Measure intraocular pressure with tonometers in unit of mmHg

    Baseline, Month 1, Month 3

  • Change from eyeball axial length at 3 months after the surgery

    Measure eyeball axial length with A-scan in unit of mm

    Baseline, Month 1, Month 3

  • Change from slit lamp examination at 3 months after the surgery

    Assess local findings with a slit lamp by same and only ophthalmologist, Dr. YH Wei

    Baseline, Month 1, Month 3

    Measure margin to reflex distance with a ruler in unit of mm by same and only ophthalmologist, Dr. YH Wei MRD-1: from the corneal light reflex to the level of the center of the upper-eyelid margin MRD-2: from the corneal light reflex to the central portion of the lower eyelid

    Baseline, Month 1, Month 3
