Comparison of mechanical debridement and trans-epithelial myopic photorefractive keratectomy: A contralateral eye study

To compare clinical outcomes between mechanical debridement photorefractive keratectomy (m-PRK) and trans-epithelial photorefractive keratectomy (t-PRK) in myopic patients.Eighty eyes of 40 myopic patients with age between 18 and 55 years were included in this study.
