为了评价准分子激光屈光性角膜切削术（PRK）治疗-10．00D以上高度近视眼的效果．我们对在本中心接受了PRK的114只-10．00D以上高度近视眼的半年随访结果进行了统计分析。分两组：T组≥－10．00D＜－15．00D，83只眼；n组）－15．00D＜－22．OOD，（等值球镜）31只限。术后探眼视力＞1．O（或＞术前最好矫正视力）在Ⅰ组为30．1％，Ⅱ组为25．8％；≥0．5（或比术前最好矫正视力下降≤4行）在Ⅰ组为65．1％，Ⅱ组为58．1％。最好矫正视力下降2行以上在Ⅰ组为9．6％，Ⅱ组为12．9％。剩余屈光度（等值球境）≤－1．00D在Ⅰ组为56．6％，Ⅱ组为18．4％；其均数及标准差在Ⅰ组为-1．14±0．99，Ⅱ组为-1．44±1．10D。角膜上皮下混浊Ⅱ组重于Ⅰ组。结果表明：PRK治疗-10D以上高度近视眼安全、有效，但屈光回退明显，其预测性及稳定性差于-10D以下近视眼。
In order to evaluate the effect of excimer laser refractive keratotomy (PRK) treatment of high myopia above -10.00D. We conducted a statistical analysis of the half-year follow-up of 114 high-myopia patients who received more than 10.00D of PRK in our center. Divided into two groups: T group ≥-10.00D <-15.00D, 83 eyes; n group) -15.00D <-22. OOD, (equivalent sphere mirror) 31 only. Postoperative eye sight> 1. O (or> best corrected visual acuity before surgery) was 30.1% in group I and 25.8% in group II, and ≥0.5 (or better than preoperative correction of visual acuity ≤ 4 lines) 65.1% in group Ⅱ and 58.1% in group Ⅱ. The best correction of visual acuity more than 2 lines in group I was 9.6%, group Ⅱ was 12.9%. The residual diopter (equivalent sphere) ≤-1.00D was 56.6% in group Ⅰ and 18.4% in group Ⅱ, the mean and standard deviation were -1.14 ± 0.99 in group Ⅰ, Ⅱ Group was -1.44 ± 1.10D. Corneal epithelial turbidity Ⅱ group heavier than the group Ⅰ. The results show that: PRK treatment of high myopia -10D above safe and effective, but significant refractive regression, its predictability and stability worse than -10D following myopia.
