【摘要】：目的对行飞秒激光制瓣LASIK(FS-LASIK)和准分子原位角膜磨镶术(LASIK)患者术后视觉质量进行比较。方法回顾性分析接受手术的近视合并散光患者60例,分为FS-LASIK组(30例,60只眼)和LASIK组(30例,60只眼)。随访3个月,比较2组术后1个月、3个月的裸眼视力(UCVA)、最佳矫正视力(BCVA)、球镜度数、柱镜度数以及高阶像差的变化。结果术后3个月,2组UCVA达到或超过术前BCVA率均为100%,术后3个月无患者BCVA较术前下降;术后3个月等效球镜度在±0.50 D范围内的百分率,2组均为80%,差异无统计学意义(P0.05);2组术后柱镜度数分别为(-0.24±0.33)D(0.50~-1.25 D)、(-0.13±0.42)D(0.75~-1.00 D),差异无统计学意义(P0.05)。术后1个月和3个月,2组高阶像差与术前相比均增大,差异有统计学意义(P0.05);术后1个月,2组水平慧差、垂直慧差及球差之间差异无统计学意义(P0.05);术后3个月,2组水平慧差、垂直慧差之间差异无统计学意义(P0.05),但FS-LASIK组球差变化值小于LASIK组(P0.05)。结论飞秒LASIK与LASIK手术治疗近视合并散光有效、安全、稳定,前者比后者引入的术后球差更少,具有更好的术后视觉质量,是一种值得在临床中进行推广的手术方法。
[Abstract]:Objective to compare the visual quality of patients treated with femtosecond laser flap making and excimer in situ keratomileusis. Methods A total of 60 patients with myopia and astigmatism underwent surgery were retrospectively analyzed. They were divided into FS-LASIK group (n = 30) and LASIK group (n = 60). Follow up for 3 months, compare the changes of uncorrected visual acuity (UCVA), best corrected visual acuity (BCVA), ball lens degree, column lens degree and high order aberration in the two groups at 1 month and 3 months after operation. Results 3 months after operation, the rate of UCVA reached or exceeded the preoperative BCVA in both groups was 100. The BCVA of no patient 3 months after operation was lower than that before operation. The percentage of equivalent spherical endoscopy in the range of 卤0.50D was 80 in both groups at 3 months after operation. There was no significant difference in the degree of post operative column endoscopy between the two groups (P 0.05). The degree of post operative column endoscopy in group 2 was -0.24 卤0.33)D(0.50~-1.25, and 0.13 卤0.42)D(0.75~-1.00, respectively. There was no significant difference between the two groups (P 0.05). After 1 month and 3 months after operation, the higher order aberration in both groups increased significantly compared with that before operation, and the difference was statistically significant (P 0.05), but there was no significant difference in horizontal, vertical and spherical aberration between the two groups at 1 month and 3 months after operation (P 0.05), and at 3 months after operation, there was no significant difference between the two groups in terms of horizontal wisdom, vertical aberration and spherical aberration. There was no significant difference between vertical wisdom difference (P 0.05), but the change of spherical aberration in FS-LASIK group was lower than that in LASIK group (P 0.05). Conclusion Femtosecond LASIK and LASIK are effective, safe and stable in the treatment of myopia complicated with astigmatism. The former has less spherical aberration than the latter, and has better visual quality. It is an operative method worth popularizing in clinic.
