【摘要】：目的:分析并探讨飞秒激光个体化准分子手术治疗近视的临床效果。方法:选取2010-01/2015-01在医院接受治疗的近视患者320例590眼,根据患者手术方案分为观察组与对照组,观察组采用飞秒激光个体化准分子手术(optimized refractive keratectomy,ORK)进行治疗,对照组则为机械刀制瓣的ORK治疗。结果:低中度近视患者中,观察组术后6mo平均视力为5.11±0.09,对照组为5.10±0.08。高度近视患者中,观察组术后6mo平均视力为5.09±0.05,对照组为5.08±0.05。两组患者术后视力均有所改善,且两组间差异无统计学意义(P0.05)。术后6mo,观察组角膜非球面系数Q明显低于对照组,差异有统计学意义(P0.05)。术后6mo观察组角膜厚度明显薄于对照组,差异有统计学意义(P0.05)。结论:飞秒激光个体化准分子手术治疗近视具有良好的手术有效性,且更好地保持了角膜的非球面形态,提高视觉质量。
[Abstract]:Objective: to analyze and discuss the clinical effect of femtosecond laser individualized excimer surgery for myopia. Methods: 320 myopia patients (590 eyes) who were treated in hospital in 2010-01 / 2015-01 were divided into observation group and control group according to the operation plan. The observation group was treated by femtosecond laser individualized excimer surgery. The control group was treated with ORK. Results: in the patients with low and moderate myopia, the average 6mo visual acuity was 5.11 卤0.09 in the observation group and 5.10 卤0.08 in the control group. In the patients with high myopia, the average visual acuity of 6mo was 5.09 卤0.05 in the observation group and 5.08 卤0.05 in the control group. The visual acuity of the two groups improved after operation, and there was no significant difference between the two groups (P 0.05). The corneal aspherical coefficient Q in the observation group was significantly lower than that in the control group at 6 moths after operation, and the difference was statistically significant (P 0.05). The corneal thickness in 6mo group was significantly thinner than that in control group (P 0.05). Conclusion: femtosecond laser individualized excimer surgery is effective in the treatment of myopia, and can better maintain the aspherical shape of cornea and improve the visual quality.
