Base curves of bandage contact lenses and their effects on post Trans-PRK vision and pain: the study protocol for a randomized clinical trial.

ABSTRACT:

Background

Transepithelial photorefractive keratectomy (Trans-PRK) is an effective and safe laser surgery for myopia. Following this procedure, a bandage contact lens is used to promote epithelial healing, reduce postoperative pain, and improve visual recovery. The base curve of these lenses may affect vision post-surgery, particularly in patients with steep corneas and high myopia. This study aims to investigate the impact of using bandage contact lenses with base curves of 8.4 mm versus 8.8 mm on visual recovery after Trans-PRK in patients with steep corneas and high myopia.

Methods

This is a randomized, double-blind, binocularly controlled, single-center trial. The study subjects are myopic patients scheduled for Trans-PRK. Both eyes in each patient will be treated consec
