Photorefractive keratectomy to treat low, medium, and high myopia: a multicenter study.
This prospective, multicenter study investigated what influence patient age, sex, and time to re-epithelialization after myopic photorefractive keratectomy (PRK) have on stability of achieved correction and intensity of corneal haze. Seven surgeons performed PRK to correct myopia on 325 eyes using the same operative procedure, type of laser, and post-PRK treatment. Follow-up was from six to 12 months. Results indicate that corneal haze intensity is influenced by the time to re-epithelialization of the treated corneal surface. Patient age and sex may also affect haze intensity, although the results from this study were not conclusive.
