To evaluate the therapeutic effects of automated lamellar keratoplasty combined with excimer laser keratectomy (ALK-E) for the correction of high myopia.
With the automated corneal shaper and Keracor 116 excimer laser, ALK-E was performed on 47 eyes of 40 cases with myopia of -8.00 to -30.00 diopters (mean, -14.55D +/- 5.14D) and the highest astigmatism 7.00D. Postoperatively, all patients have been followed up for at least 3 months.
The refractive status and visual acuity tend to be stable about 1 month postoperatively. For myopes below -15.00D, the mean refraction was -1.33D +/- 1.05D at 3 months, and 66.7% achieved their preoperative best corrected visual acuity. For myopes over -15.00D, the mean refraction was -2.42D +/- 1.84D at 3 months and 52.9% achieved their preoperative best corrected visual acuity.
The early therapeutic results of ALK-E for treatment of high myopia are very promising. However, the operative techniques, parameters and remote therapeutic results remain to be further studied.
评估自动板层角膜成形术联合准分子激光角膜切削术（ALK-E）矫正高度近视的治疗效果。
使用自动角膜成形仪和Keracor 116准分子激光，对40例近视度数在-8.00至-30.00屈光度（平均-14.55D±5.14D）且最高散光为7.00D的患者的47只眼进行ALK-E手术。术后，所有患者均随访至少3个月。
术后约1个月屈光状态和视力趋于稳定。对于近视度数低于-15.00D的患者，3个月时平均屈光度为-1.33D±1.05D，66.7%的患者达到术前最佳矫正视力。对于近视度数高于-15.00D的患者，3个月时平均屈光度为-2.42D±1.84D，52.9%的患者达到术前最佳矫正视力。
ALK-E治疗高度近视的早期治疗效果非常有前景。然而，手术技术、参数及远期治疗效果仍有待进一步研究。
