Comparison of Single-Step Transepithelial Photorefractive Keratectomy With or Without Mitomycin C in Mild to Moderate Myopia

Corneal haze is a common complication of photorefractive keratectomy (PRK). Clinically insignificant haze affects almost every eye undergoing PRK, whereas clinically significant haze affects 0.3% to 3% of the treated eyes.1 Corneal haze can reduce the efficacy of the surgery by leading to fluctuations in vision, irregular astigmatism, and myopic regression.2 Mitomycin C (MMC) has been successful in preventing haze after PRK in studies of low, medium, and high myopia.3 –5 There are several studies suggesting MMC application during PRK.5–8 However, in a study of eyes with mild to moderate
