目的：报告视轴自动居中远视 LASIK 与视线 (LOS) 居中相比的屈光结果。 方法：使用 NIDEK 高级视觉准分子激光平台 (NAVEX) 治疗 LOS 居中远视眼 (LOS 组) 181 只和视轴居中远视眼 (视轴组) 64 只。根据 LOS 和同轴瞄准的角膜光反射之间的位置关系，将视轴坐标数字化传输到准分子激光系统。所有眼睛均采用 6.5 毫米光学区和 9.0 毫米过渡区进行治疗。回顾性分析术后三个月的结果。结果：术前视轴组明显屈光球当量（MRSE）为+2.57+/-1.26屈光度（D）（范围：0.13～5.63 D），LOS组为+2.46+/-1.32 D（范围：0.38～5.63 D）。视轴组术后MRSE为+0.29+/-0.70 D（范围：-1.00～1.75 D），LOS组术后MRSE为+0.19+/-0.57 D（范围：-0.75～1.75 D）。术后，视轴组81%（38/47）的眼睛和LOS组64%（74/116）的眼睛D为+/-0.50D。在视轴组中，与相比，视轴组91%（44/52）的眼睛和LOS组92%（102/109）的眼睛保持最佳眼镜矫正视力在一线内。结论：以视轴为中心的远视 LASIK 的初步经验表明结果是安全且可预测的。
PURPOSE: To report refractive outcomes of hyperopic LASIK with automated centration on the visual axis compared with centration on the line of sight (LOS).METHODS: The NIDEK Advanced Vision Excimer Laser platform (NAVEX) was used to treat 181 hyperopic eyes with centration on the LOS (LOS group) and 64 hyperopic eyes with centration on the visual axis (visual axis group). The coordinates of the visual axis were digitally transferred to the excimer laser system based on the positional relationship between the LOS and the coaxially sighted corneal light reflex. All eyes were treated with a 6.5-mm optical zone and 9.0-mm transition zone. Three-month postoperative outcomes were retrospectively analyzed.RESULTS: The preoperative manifest refraction spherical equivalent (MRSE) was +2.57+/-1.26 diopters (D) (range: 0.13 to 5.63 D) in the visual axis group and +2.46+/-1.32 D (range: 0.38 to 5.63 D) in the LOS group. The postoperative MRSE was +0.29+/-0.70 D (range: -1.00 to 1.75 D) in the visual axis group and +0.19+/-0.57 D (range: -0.75 to 1.75 D) in the LOS group. Postoperatively, 81% (38/47) of eyes in the visual axis group and 64% (74/116) of eyes in the LOS group were +/-0.50 D. In the visual axis group, 91% (44/52) of eyes and 92% (102/109) of eyes in the LOS group maintained best spectacle-corrected visual acuity within one line compared with preoperatively.CONCLUSIONS: Initial experience with hyperopic LASIK centered on the visual axis indicated safe and predictable outcomes.
