目的 :探讨准分子激光角膜切削术 (PRK)治疗近视眼的近期疗效。方法 :对 6 6 1只不同度数的患眼经 PRK术后疗效的分析。结果 :视力恢复达 1.0以上的 组 (≤ -3.0 0 D) 70眼 ,占总数 75眼的 93.3% , 组 (≤ -6 .0 0 D) 2 33眼 ,占总数 2 6 7眼的 87.3% , 组 (≤ -12 .0 0 D) 173眼 ,占总数 2 6 8眼的 6 4.6 % , 组 (>-12 .0 0 D) 3眼 ,占总数 5 1眼的 5 .8%。剩余屈光度 :≤ -0 .5 0 D的 组 73眼 97.3% ; 组 2 5 6眼 (95 .8% ) ; 组 175眼 (6 5 .3% ) ; 组 4眼 (7.8% )。角膜上皮下雾状浑浊 (Haze分级 ) :角膜完全透明 组6 1眼 (81.3% ) ; 组 2 0 3眼 (76 .0 % ) ; 组 16 2眼 (6 0 .4% ) ; 组 18眼 (35 .3% )。结论 :PRK治疗 -12 .0 0 D以下特别是 -6 .0 0 D以下近视 ,1年疗效满意 ,稳定性好 ;对 >-12 .0 0 D不宜采用。
Objective: To investigate the short-term effect of excimer laser keratectomy (PRK) in the treatment of myopia. Methods: Six hundred and sixty-one patients with different degrees of PRK after eye surgery efficacy analysis. Results: Seventy eyes (≤ -3.0 0 D) with visual acuity of more than 1.0 recovered accounted for 93.3% of the total 75 eyes, while 2 33 eyes (≤ -6.0 0 D) accounted for 87.3% of the total 267 eyes. , 173 eyes (≤ -12 .0 0 D), 6 4.6% of the total 206 eyes, and 3 eyes (> -12 .0 0 D) accounting for 5.8% of the total 51 eyes. Remaining diopter: ≤0.500D Group 73 eyes 97.3%; Group 246 (95.8%); Group 175 eyes (6.5%); Group 4 eyes (7.8%). Corneal submucosal haze (Haze grading): 6 eyes (81.3%) in complete corneal clear group, 203 eyes (76.0%) in cornea group, 16 eyes (60.4%) in group and 18 eyes (35.3%). Conclusion: PRK treatment below -12.0 D, especially below -6.0 0 D myopia, 1 year satisfactory results, good stability;> -12. 0 0 D should not be used.
