摘要：

Purpose: To evaluate and compare the clinical outcomes, including visual acuity, refractive errors, and aberrations, between aberration-free transepithelial photorefractive keratectomy (PRK) and corneal wavefront-guided transepithelial PRK in eyes with myopic astigmatism. Setting: Yonsei University College of Medicine and Eyereum Eye Clinic, Seoul, South Korea. Design: Retrospective comparative case series. Methods: Patients with myopic astigmatism were treated with aberration-free transepithelial PRK or corneal wavefront-guided transepithelial PRK using a 1050 Hz high-repetition excimer laser. The safety, efficacy, predictability, and corneal aberrations were compared preoperatively and 1, 2, 3, and 6 months postoperatively. Results: The study comprised 188 patients (188 eyes); 91 eyes had aberration-free transepithelial PRK and 97 eyes comeal wavefront-guided transepithelial PRK. Six month after surgery, the mean uncorrected distance visual acuity was comparable (-0.06 logMAR +/- 0.07 [SD] aberration-free group; -0.06 +/- 0.06 logMAR wavefront-guided group). The safety, efficacy, and predictability of refractive and visual outcomes were also comparable between groups. Corneal total root-mean-square (RMS) higher-order aberrations (HOAs) increased after treatment in both groups, although fewer RMS HOAs were induced in the corneal wavefront-guided group than in the aberration-free group. Spherical aberration increased similarly after treatment in both groups. However, coma and trefoil increased only in the aberration-free group. Conclusions: Aberration-free transepithelial PRK and corneal wavefront-guided transepithelial PRK were safe and effective for correction of myopic astigmatism without difference in visual acuity and refractive outcomes. However, the corneal wavefront-guided profile induced fewer corneal aberrations than the aberration-free profile. (C) 2017 ASCRS and ESCRS
