8-to-10-Year Follow-Up Results of Photorefractive Keratectomy and Risk Factors for Myopia Regression (Including Near Work Activity) in Southeast Iran

PRK proved to be a safe, effective, and predictable procedure in the long term. Myopia and ablation depth were significant risk factors for myopic regression, while corneal diameter was protective. Near-work activity did not affect myopia progression. Under-corrected eyes for astigmatism exhibited a higher magnitude of pre-operative astigmatism compared to over-corrected eyes.
