摘要
目的 评价准分子激光治疗中度近视的有效性和预测性。方法 分别应用准分子激光屈光性角膜切削术和准分子激光原位角膜磨镶术对中度近视共 10 85眼进行治疗和临床疗效对照分析。结果 术前准分子激光屈光性角膜切削术组和准分子激光原位角膜磨镶术组平均裸眼视力分别为 (0 .11± 0 .0 5 )和 (0 .0 6±0 .0 4 ) (P <0 .0 5 ) ,平均等值球镜屈光度分别为 (- 3.6 3± 1.5 5 )、(- 4 .87± 0 .93)D(P <0 .0 5 ) ;术后 6个月准分子激光屈光性角膜切削术组平均裸眼视力为 (1.12± 0 .2 3) ,等值球镜屈光度为 (- 0 .4 9± 0 .4 3)D ,而准分子激光原位角膜磨镶术组平均裸眼视力为 (1.18± 0 .17) (P >0 .0 5 ) ,等值球镜屈光度为 (- 0 .5 8± 0 .4 0 )D(P >0 .0 5 )。结论 准分子激光屈光性角膜切削术和准分子激光原位角膜磨镶术两种方法治疗中度近视均具有准确性高、预测性良好的特点。
Objective To assess the effectiveness and predictabilit y of excimer laser for correction of moderate myopia. Methods 1085 ey es with preoperative refraction of -3.00 to -6.00 diopters were trea ted with P hotorefractive keratectomy(PRK)or Laser in situ keratomileusis(LASIK),and the c linical results were analyzed. Reaults Preoperatively, the aver-age uncorrected visual acuities in PRK group and in LASIK gro up were (0.11±0.05) and (0.06±0.04) respectively(P<0.05),and the avera ge refractions were (-3.63±1.55) diopters and (-4.87±0.93) diopters res pectively (P<0.05).Six months after operation, the average uncorrected visua l acuity in PRK group was (1.12±0.23), the average refraction was (-0.49±0 .43) diopters, the average uncorrected visual acuity in LASIK group was (1.18 ±0.17)(P>0.05), and the average refraction in LASIK was (-0.58±0.40) d iopters (P>0.05). Conclusion Both PRK and LASIK are accurate an d predictable for correction of moderate myopia.
