Summary
The goal of this interventional comparative study is to assess the efficacy and safety of a
novel regimen of preservative-free topical anesthetics for controlling early postoperative
pain following single-step transepithelial PRK surgery.
The main questions it aims to answer are:
- Question 1: Are topical anesthetics effective in reducing post-PRK pain?
- Question 2: Do topical anesthetics inversely affect the epithelial healing duration?
Participants will undergo a bilateral single-step transepithelial PRK surgery to correct
their refractive errors and will receive a standard post-PRK treatment regimen for both
eyes. Additionally, one eye will be offered a preservative-free topical anesthetic as an
experimental group and the other eye will be offered a preservative-free artificial tear
as a control placebo group.
