摘要
目的观察Q值调整的个体化准分子激光角膜屈光手术治疗近视的安全性及有效性。方法780例(1560眼)近视患者采用Q值调整的个体化准分子激光角膜屈光手术治疗,观察记录术后裸眼视力、最佳矫正视力、Q值等并进行统计学分析。结果术后1周平均裸眼视力为1.09±0.16,术后3个月为1.06±0.12,与术前(0.15±0.05)相比差异均有统计学意义(P<0.05)。术后1周平均最佳矫正视力为1.13±0.17,术后3个月为1.10±0.16,与术前(0.82±0.14)相比差异均有统计学意义(P<0.05)。术后屈光度在预期值±0.50D以内的占98.08%;术后1周平均屈光度为+0.56±0.16)D,术后3个月为(0.25±0.08)D。手术前后Q值变化有统计学意义(P<0.05)。结论Q值调整的个体化准分子激光角膜屈光手术治疗近视是安全、有效的。
Objective To study the safety and clinical effect of Q-value guided customized LASIK（Q-LASIK） for myopia. Methods A total of 780 patients （ 1 550 eyes） were treated with Q-LASIK. The naked vision,best corrected visual acuity, Q value after operation were recorded, and data were statistical analyzed. Results The mean naked vision was 1.09±0. 15 and 1.05±0. 12 at 1 week and 3 months post-operatively,respectively, and there were statistical difference for each compared with 0.15 ± 0.05 pre-operatively（P 〈 0.05 ）. The mean best corrected visual acuity were 1.13 ± 0.17 and 1. 10±0. 15 at 1 week and 3 months post-operatively,respectively,and there were statistical difference for each compared with 0.82± 0.14 pre-operatively（P 〈 0.05 ）. The post-operative diopter between predicted value ± 0.50 D was 98.08% ; The mean postoperative diopter was（0.55±0.15）D at 1 week post-operatively,and （0.25±0. 08）D at 3 months post-operatively. The changes of Q value had significant difference between pre- and post-operation （P 〈 0.05 ）. Conclusion Q-LASIK is safe and effective for myopia.
