PURPOSE
To evaluate the effects of photorefractive keratectomy (PRK) combined with corneal wavefront-guided ablation profiles and hyperaspheric ablation profiles on changes in higher-order aberrations (HOAs).
SETTING
Yonsei University College of Medicine and Eyereum Clinic, Seoul, South Korea.
DESIGN
Comparative observational case series.
METHODS
Medical records of patients who had corneal wavefront-guided hyperaspheric PRK, corneal wavefront-guided mild-aspheric PRK, or non-corneal wavefront-guided mild-aspheric PRK were analyzed. The logMAR uncorrected distance visual acuity (UDVA), manifest refraction spherical equivalent (MRSE), and changes in corneal aberrations (root-mean-square [RMS] HOAs, spherical aberration, coma) were evaluated 1, 3, and 6 months postoperatively.
RESULTS
The records of 61 patients (96 eyes) were reviewed. There was no statistically significant difference in logMAR UDVA or MRSE between the 3 groups at any timepoint. Corneal RMS HOAs were significantly smaller in the corneal wavefront-guided hyperaspheric group and the corneal wavefront-guided mild-aspheric group than in the noncorneal wavefront-guided mild-aspheric group at each timepoint. Corneal spherical aberration was significantly smaller for corneal wavefront-guided hyperaspheric PRK than for noncorneal wavefront-guided mild-aspheric PRK 6 months postoperatively. Changes in corneal spherical aberration (preoperatively and 6 months postoperatively) in corneal wavefront-guided hyperaspheric PRK were significantly smaller than in corneal wavefront-guided mild-aspheric PRK (P = .046). Corneal coma was significantly smaller with corneal wavefront-guided hyperaspheric PRK and corneal wavefront-guided mild-aspheric PRK than with noncorneal wavefront-guided mild-aspheric PRK 3 months and 6 months postoperatively.
CONCLUSION
Corneal wavefront-guided hyperaspheric PRK induced less corneal spherical aberration 6 months postoperatively than corneal wavefront-guided mild-aspheric PRK and noncorneal wavefront-guided mild-aspheric PRK.

目的
评估准分子激光角膜切削术（PRK）联合角膜波前引导消融模式和超球面消融模式对高阶像差（HOA）变化的影响。
设置
韩国首尔延世大学医学院和 Eyereum 诊所。
设计
比较观察性病例系列。
方法
分析了接受角膜波前引导超球面 PRK、角膜波前引导轻度球面 PRK 或非角膜波前引导轻度球面 PRK 的患者的病历。术后 1、3 和 6 个月评估对数视力矫正（UDVA）、等效球镜（MRSE）和角膜像差（均方根 [RMS] HOA、球差、彗差）的变化。
结果
共回顾了 61 例（96 只眼）患者的记录。在任何时间点，3 组之间的 logMAR UDVA 或 MRSE 均无统计学差异。在每个时间点，角膜波前引导超球面组和角膜波前引导轻度球面组的角膜 RMS HOA 均显著小于非角膜波前引导轻度球面组。角膜波前引导超球面 PRK 的角膜球差显著小于非角膜波前引导轻度球面 PRK，术后 6 个月。角膜波前引导超球面 PRK 术后 6 个月角膜球差的变化（术前和术后 6 个月）显著小于角膜波前引导轻度球面 PRK（P=0.046）。角膜波前引导超球面 PRK 和角膜波前引导轻度球面 PRK 的角膜彗差显著小于非角膜波前引导轻度球面 PRK，术后 3 个月和 6 个月。
结论
与角膜波前引导轻度球面 PRK 和非角膜波前引导轻度球面 PRK 相比，角膜波前引导超球面 PRK 术后 6 个月时引起的角膜球差更小。
