ABSTRACT
The aim of this study was to evaluate the long-term outcome of excimer laser myopic photorefractive keratectomy (PRK). We undertook an 11-year prospective follow-up study of visual and refractive outcomes in 46 patients (85 eyes). The main outcome measures were predictability, efficacy, stability and safety of PRK. At 11 years after the operation, 56.5% of eyes were within +/-0.5 D of attempted correction and 81.2% were within +/-1.0 D; 87% had vision of 20/40 or better, and 52% had 20/20 or better. The best spectacle-corrected visual acuity was unchanged or improved in 91% of eyes at 11 years. Eyes with moderate and severe myopia showed a significant change between 3 and 11 years. PRK surgery for myopia shows predictable and stable results in the long term, with a slight regression in refraction, mainly for patients with severe myopia.
