# Transcanthal Canthopexy for Involutional Lower Eyelid Entropion Corrects Horizontal Laxity

## TL;DR

This study shows that a specific eyelid surgery effectively corrects horizontal laxity in patients with a common eyelid condition.

## Contribution

The study introduces transcanthal canthopexy combined with retractor advancement as a novel method to address horizontal laxity in involutional lower eyelid entropion.

## Key findings

- Horizontal laxity significantly improved after surgery, as measured by the pinch test.
- No cases experienced recurrence of the condition within 6 months post-surgery.

## Abstract

In this prospective observational study, we aimed to examine improvements in horizontal laxity after lower eyelid retractor advancement and transcanthal canthopexy for involutional lower eyelid entropion. The study included 19 sides in 15 patients with involutional entropion who underwent transcanthal canthopexy with the advancement of the lower eyelid retractor. Using the pinch test, the distance from the lowest part of the corneal limbus to the eyelid margin was measured using callipers. All measurements were performed preoperatively and at postoperative 3 and 6 months. Using the pinch test, the distance from the lowest part of the corneal limbus to the lower eyelid margin was significantly shortened during each postoperative follow-up period. None of the included cases experienced recurrence. Our results indicated that transcanthal canthopexy could preserve postoperative horizontal tightness.
