准分子激光原位角膜磨镶术治疗—10D以上近视疗效观察

CORRECTION OF MYOPIA LESS THAN- 10D BY EXCIMER LASER ASSISTED IN SITU KERATOMILEUSIS

采用LASIK手术治疗-10D以上近视303眼。术前平均裸视力0.1±0.05(0.005～1.0),平均屈光度(-15.25±5.25)D(-10.00D～-26.00D),散光度数(-4.25±2.12)D(-0.75～-6.25D),术前平均屈光力(K)值43.60±1.52。随访8～12个月,平均裸眼视力升至0.52±0.25(0.25～1.0),平均屈光度降至(+0.85±2.59)D,K值降至37.53±1.73,散光度数降至(0.00±1.52)D(0.00～-3.00D)。结果表明LASIK治疗-10D以上高度近视效果可靠,预测性强,手术精确度高,优于PRK。

303 eyes with myopia less than - 101) were corrected by excimer laser assisted in situ keratomileusis (LASIK). The mean preoperative naked visual acuity was 0. 1 ± 0. 05, mean refraction was ( - 15. 25±5. 25)D, mean preoperative astigmia was (-4. 24 ± 2. 12)D, and mean preoperative refraction K value was 43. 60±1. 52. The postoperative following - up lasted 8 to 12 months. After the correction, the mean naked visual acuity reached 0. 52±±0. 25, mean refraction became (0. 85 ±2. 59)D, K value was 37. 53± 1. 73, and mean astigmia was ((0. 00± 1. 52)D. It is showed that the corrective effects of LASIK on high myopia is very good.
