PRK Enhancement for Residual Refractive Error After Primary PRK: A Retrospective Study [PDF]
Ophthalmology and Therapy, 2021 The efficacy and safety of photorefractive keratectomy (PRK) has been well documented, but outcomes of PRK enhancement following PRK remain understudied. This study aimed to evaluate the safety, efficacy, and predictability of PRK enhancement in patients with residual refractive error after primary PRK and compare these results to prior studies as well
