目的观察准分子激光上皮瓣下角膜磨镶术(LaserSuberpithelialKeratomileusis,LASEK)治疗高度近视散光的疗效。方法高度近视散光病人65例109眼,用Meditec-MEL70飞点扫描准分子激光机行LASEK治疗,术后随访3～12月。结果术后6月裸眼视力0.4～1.2(0.88±0.21),其中17眼(15.60%)好于术前最佳矫正视力1～2行,术后3月时0.5级haze25眼(22.94%),98眼(89.9%)术后散光在±0.75D以内,残留散光平均为-0.51D,散光矫正者占77.3%。结论LASEK治疗高度散光具有良好的安全性、有效性和可预测性,与其他手术相比在安全性方面具有更明显的优势,是一种值得推荐的治疗高度近视散光的手术方式。
Objective To observe the effect of laser subepithelial keratomileusis (LASEK) on high myopic astigmatism. Methods A total of 109 eyes of 65 patients with myopic astigmatism were treated with LITEK Meditec-MEL70 flying spot scanning excimer laser. The patients were followed up for 3 to 12 months. Results The uncorrected visual acuity was 0.4 ~ 1.2 (0.88 ± 0.21) in 6 months postoperatively. Among them, 17 eyes (15.60%) were better than preoperative best corrected visual acuity (1 ~ 2 lines), 0.5 months postoperative haze 25 eyes (22.94% 98 eyes (89.9%) postoperative astigmatism within ± 0.75D, residual astigmatism average -0.51D, astigmatism accounted for 77.3%. Conclusion LASEK has a good safety, efficacy and predictability in the treatment of high astigmatism. Compared with other surgery, LASEK has more obvious advantages in safety and is a recommended surgical method for the treatment of myopic astigmatism.
