作者报道了自动板层角膜成形术(ALK)治疗近视的最初结果并对ALK的短期效果、安全性及可预测性进行了评估。对接受ALK治疗的81例(128眼)患者随诊平均13.6个月,包括近视120眼和放射状角膜切开术(RK)后残留近视8眼。术前平均屈光度为-7.48±2.05D。结果显示,裸眼视力达20/40或以上者占86.4%;76.2%的术眼屈光度在±1.00D以内,93.6%在±2.00D以内。其中77%的术眼在ALK术后又接受了RK或散光性角膜切开术(AK)。并发症包括:散光较术前增加1.00D以上(4%);持续不规则散光(4%);过矫达+1.00D以上(4%);角膜上皮长入手术界面(2%);角膜板层片丢失(1/128);最佳矫正视力下降2行或以上者(6.3%)。本研究表明,ALK手术对于矫正高度近视或RK术后残留近视是一种安全、有效、可预测的方法,若再附加RK或AK手术,则能得到更满意的视力和屈光结果
The authors reported on the initial results of autoskeletal keratoplasty (ALK) for the treatment of myopia and evaluated the short-term effects, safety and predictability of ALK. Eighty-one patients (128 eyes) receiving ALK were followed up for an average of 13.6 months, including 120 eyes of myopia and 8 eyes of residual myopia after radial keratotomy (RK). The average preoperative refractive power was -7.48 ± 2.05D. The results showed that the naked eye visual acuity of 20/40 or more accounted for 86.4%; 76.2% of the eye refractive power within ± 1.00D, 93.6% within ± 2.00D. Of these, 77% received RK or astigmatism (AK) after ALK surgery. Complications included astigmatism increased 1.00D or more (4%) compared with preoperative; persistent irregular astigmatism (4%); overcorrection + 1.00D or more (4%); corneal epithelial growth into the surgical interface (2%); Corneal lamellar loss (1/128); best corrected visual acuity decreased by 2 lines or more (6.3%). This study shows that ALK surgery is a safe, effective and predictable method for the correction of residual myopia after high myopia or RK surgery. If additional RK or AK surgery is performed, more satisfactory visual acuity and refractive results can be obtained
