Abstract

Purpose: To compare the visual and refractive outcomes of low versus high myopic correction using laser in situ keratomileusis (LASIK) surgery.

Methods: Patients who underwent myopic LASIK between January 2013 and December 2023 were included. Eyes were divided into two groups based on preoperative myopia severity: low (0.50 to 3.00 diopters [D]) and high (≥ 6.00 D). Adjustments were made to account for differences in baseline and intraoperative parameters.

Results: In this retrospective study, 12,074 eyes of 6,985 patients were included. Mean spherical equivalent (SEQ) was -6.84 D for high myopia and -2.02 D for low myopia. High myopia was found in 6.7% of patients (n = 813), demonstrating preoperative steeper corneas (maximum keratometry 44.49 vs 44.21 D, P < .001) and worse uncorrected and corrected distance visual acuity (UDVA and CDVA) (2 vs 0.77 logMAR, P < .001; 0.03 vs 0.02 logMAR, P < .001, respectively). Following LASIK, the high myopia group had worse UDVA (0.04 vs 0.01 logMAR, P < .001) and CDVA (0.03 vs 0.01 logMAR, P < .001), higher cylinder (-0.08 vs -0.05 D, P < .001), and SEQ (-0.12 vs -0.07 D, P = .015). Keratometry measurements were flatter in the high myopia group (average: 38.43 vs 41.83 D, P < .001). After accounting for differences in baseline and intraoperative parameters, all of the above-mentioned parameters remained statistically significant. High myopia was not associated with higher re-treatment rates (P = .27).

Conclusions: Although LASIK surgery yielded satisfactory short-term outcomes in both low and high myopia, high myopia showed slightly less favorable refractive results. However, overall results were clinically acceptable in both groups. Similar re-treatment rates may reflect patient satisfaction or variability in surgeons' thresholds for offering enhancement procedures.

高度和高度近视的LASIK疗效比较：大数据分析。

目的：比较激光原位角膜磨圆术（LASIK）低、高度近视矫正的视力和屈光效果。方法：选取2013年1月至2023年12月接受近视LASIK手术的患者。根据术前近视程度将眼睛分为低（0.50 ~ 3.00屈光度[D]）和高（≥6.00 D）两组。根据基线和术中参数的差异进行调整。结果：本回顾性研究纳入6,985例患者12,074只眼。高度近视的平均球当量（SEQ）为-6.84 D，低度近视为-2.02 D。6.7%的患者（n = 813）高度近视，术前角膜较陡（最大角膜度数44.49比44.21 D, P < 0.001），未矫正和矫正距离视力（UDVA和CDVA）较差(2比0.77 logMAR, P < 0.001；0.03 vs 0.02 logMAR, P < 0.001)。LASIK术后，高度近视组UDVA （0.04 vs 0.01 logMAR, P < 0.001）、CDVA （0.03 vs 0.01 logMAR, P < 0.001）较差，柱度（-0.08 vs -0.05 D, P < 0.001）较高，SEQ （-0.12 vs -0.07 D, P = 0.015）。高度近视组的角膜测量值较低（平均：38.43 D vs 41.83 D, P < 0.001）。在考虑了基线和术中参数的差异后，上述所有参数仍具有统计学意义。高度近视与较高的再治疗率无关（P = 0.27）。结论：虽然LASIK手术对低度和高度近视均有满意的短期效果，但高度近视的屈光效果稍差。然而，两组的总体结果在临床上都是可以接受的。类似的再治疗率可能反映了患者满意度或外科医生提供强化手术的阈值的差异。
