Effect of trichiasis surgery on visual acuity outcomes in Ethiopia.

ABSTRACT:

Objectives

To determine the effect of trichiasis surgery on visual acuity.

Methods

A total of 439 participants in the Surgery for Trichiasis, Antibiotics to Prevent Recurrence (STAR) trial had visual and subjective concerns measured before and 6 months after surgery. Trichiasis surgery was performed in at least 1 eye by integrated eye care workers.
