目得：目的：比较角膜光反射（CSCLR）中心与瞳孔中心（LOS）中心准分子激光治疗近视眼的屈光效果。对于CSCLR组，激光消融距离视轴近80%。结果：术前CSCLR组的明显屈光等效球镜（MRSE）为-4.88 ± 1.55D（范围：-8.50 ~-1.25D），LOS组为-5.05 ± 1.63D（范围：-9.75 ~-1.50D）。CSCLR组的术后MRSE为0.17 +/- 0.39 D（范围：-1.38至+1.25 D），LOS组为0.19 +/- 0.48 D（范围：-1.63至+1.88 D）。CSCLR组的安全性（1.18）和有效性（1.047）指数在统计学上显著高于LOS组（分别为1.138和0.997）（CSCLR和LOS之间的差异P0.25 mm，有利于CSCLR组。高阶像差（P= 0.04）和昏迷（P
PURPOSE: To compare refractive outcomes of myopic LASIK with centration on the coaxialiy sighted corneal light reflex (CSCLR) to centration on the center of the pupil (line of sight [LOS]).METHODS: The NIDEK CXIII excimer laser was used to treat 268 eyes with centration on the CSCLR (CSCLR group) and 288 eyes with centration on the LOS, (LOS group). For the CSCLR group, the laser ablation was delivered 80% closer to the visual axis. One-month postoperative outcomes were compared.RESULTS: Preoperative manifest refraction spherical equivalent (MRSE) was -4.88 +/- 1.55 diopters (D) (range: -8.50 to -1.25 D) in the CSCLR group an -5.05 +/- 1.63 D (range: -9.75 to -1.50 D) in th LOS group. The postoperative MRSE was 0.17 +/- 0.39 D (range: -1.38 to +1.25 D) in the CSCLR group and 0.19 +/- 0.48 D (range: -1.63 to +1.88 D) in the LOS group. Safety (1.18) and efficacy (1.047) indices were statistically significantly higher in the CSCLR group compared to the LOS group (1.138 and 0.997, respectively) (P0.25-mm difference between the CSCLR and LOS, favoring the CSCLR group. A statistically significantly greater induction of higher order aberrations (P=.04) and coma (P
