LASEK治疗近视疗效观察

Early results after laser epithelial keratectomileusis for myopia

目的 评价LASEK治疗近视的早期疗效。方法 对41例(81眼)不同屈光度(-2 . 75D～-14 . 0 0D)的近视进行LASEK手术,观察术中术后并发症,并对术后1～6月裸眼视力、屈光状态及角膜上皮下雾状浑浊(haze)进行随访。结果 2例(4眼)Ⅰ级haze ,3月时视力低于术前矫正视力1～3行,为轻度近视状态(-0 . 75D～-3 . 2 5D)。1例(2眼)Ⅱ级haze ,3月视力下降,屈光回退。6月回退到术前屈光状态。其余病例6月时视力均在0 . 5以上,达1 0者62眼占总复诊人数(76眼)的81 . 5 8%。屈光稳定于±1 . 0D以内,haze 0～0 . 5级者70眼占复诊人数(76眼)的92 . 11%。结论 LASEK是治疗近视有效方法之一,但也存在明显并发症。

Objective To assess the early curative effects of laser epithelial keratectomileusis(LASEK)for myopia.Methods 41 patients (81 eyes)with a refraction of (-2.75D～-14.00D)diopters were treated and followed for 6 months after operation about their postoperative uncorrected visual acuity(UCVA),refraction,corneal haze and other complications.Result The Ⅰ grade haze was found in four eyes,Ⅱ grade haze was found in two eyes and all these eyes have decreased in UCVA and refraction by 6 months.As for other eyes,all the UCVA were above 0.5,81.58% of which were at least 1.0,and their refraction were within+1.00～-1.00(D),92.00% of them had 0～0.5 degree haze Conclusion Laser epithelial keratectomileusis(LASEK)is one of the effective methods to treat myopia,but it also has complications.
