New treatment option for Esophoria
Official title Prism Adaptation in Symptomatic Esophoria - Effect of Shorter Time Intervals and Surgical Outcomes Based on Prism Adaptation
ClinicalTrials.gov ID: NCT06729710
What this study is testing
- What it's testing
- This study is a prospective randomized study aiming to investigate the effect of prism adaptation before surgery for symptomatic esophoria on the number of reoperations, the occurrence of over- and under-correction after the first surgery, and symptom resolution. Additionally, we aim to define the optimal duration of prism adaptation.
