Abstract

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.

摘要

目的

报告与视轴对中相比，基于视轴自动对中的远视性准分子原位角膜磨镶术（LASIK）的屈光结果。

方法

使用NIDEK先进视觉准分子激光平台（NAVEX）治疗181只视轴对中的远视眼（视轴组）和64只视轴对中的远视眼（视轴组）。根据视轴与同轴观察到的角膜光反射之间的位置关系，将视轴的坐标数字传输到准分子激光系统。所有眼睛均接受6.5毫米光学区和9.0毫米过渡区治疗。回顾性分析术后三个月的结果。

结果

视轴组术前平均等效球镜度（MRSE）为+2.57±1.26屈光度（D）（范围：0.13至5.63 D），视轴组为+2.46±1.32 D（范围：0.38至5.63 D）。视轴组术后MRSE为+0.29±0.70 D（范围：-1.00至1.75 D），视轴组为+0.19±0.57 D（范围：-0.75至1.75 D）。术后，视轴组81%（38/47）的眼睛和视轴组64%（74/116）的眼睛在±0.50 D范围内。在视轴组中，91%（44/52）的眼睛和视轴组92%（102/109）的眼睛与术前相比，最佳矫正视力保持在一行以内。
