MethodsThis pilot study included five eyes of five patients with a mean spherical equivalent of −5.1±1.46D (range from −2.75 to −6.50D). In all cases, ametropia and irregular astigmatism was corrected with topography-guided customized PRK. Ocular examinations with topographic analysis were performed preoperatively as well as at 1, 3 and 6 months after surgery. ResultsAll eyes gained postoperatively at least three Snellen lines of uncorrected visual acuity. Mean refractive spherical equivalent was 0.62±0.63D (range from −0.25 to −1.75D) at 6 months postoperatively. ConclusionOur pilot study suggests that customized PRK can be a safe and effective method for treating ametropia and irregular astigmatisms after PK. Future studies with larger samples and longer follow-ups should be performed to confirm these results. ER -
