LASEk治疗高度近视散光的疗效观察

LASEK for correction of high myopia and astigmatism

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 safety and efficacy of laser subepithelial keratomileusis （LASEK） for the treatment of high myopia and astigmatism. Methods LASEK was performed in 109 eyes of 65 patients with high myopia and astigmatism.The preoperative uncorrcected visual acuity （UCVA） were 0.01～0.5（0.08 ±0.08）.The preoperative best corrected visual acutity（BUVA） were 0.4-1.0（0.88 ±0.17）.The preoperative sphere were -0.25D～13.5D（-5.72 ±2.67D）.The preoperative cylinder were -2～6D（-2.79±0.82D）.Followed up 3～12 months. Results The postoperative UCVA were 0.4-1.2（0.88 ±0.21） and better than the BCVA in 17 of 109 eyes（1 5.60%）at 6 months after surgery.The 0.5 grade haze was found in 25 eyes at 3 months after surgery .The refractive error after surgery was less than ±0.75Din 98 eyes.The average residual astigmatism was -0.51D. Conclusion LASEK was one of methods for the correction of high myopia and astigmatism safely and effectively.
