摘要
目的分析准分子激光上皮下角膜磨镶术(LASEK)治疗异常近视眼产生的并发症,并探讨其发生原因及预防措施。方法异常眼(眼球小,睑裂小、眼窝深、角膜薄)312例(611眼),均为中高度近视(-5.00D--13.00D),行LASEK后随访1年,观察其上皮愈合、haze、视力变化等并发症。结果术中角膜上皮瓣不完整72眼占11.7%;术后角膜上皮愈合延迟21眼占3.4%;角膜感染1眼占0.15%;术后6月haze0.5级56眼(9.1%),1级14眼(2.3%);2级2眼(0.3%);术后皮质类固醇性高眼压7眼占1.1%。术后1年屈光回退〉1.00D者51眼,占8.3%;散光度增加〉1.00D者19眼,占3.1%;矫正视力较术前下降1行者9眼,占1.4%。结论LASEK治疗异常近视眼是安全有效的,但易出现一定的并发症,手术技巧的提高、手术器械的改良、术后病人的配合以及合理的用药都有助于减少手术并发症的发生。
Objective To analyze the complications of laser subepithelial keratomileusis (LASEK) for unusual myopic eyes, and to investigate the causes and discuss the prevention of these complications. Methods The unusual myopic eye was characterized as small globe, blepharophimosis, deep socket of eyeball or thin cornea. LASEK was done to correct high and medium myopia ( -5.00 D - - 13.00D) on 611 eyes in 312 cases. They were followed up for a period of 12 months. The epithelium, haze, visual acuity and complications were observed. Results Intraoperative incompletely corneal epithelial flap occurred in 72 eyes (11.7% ), delayed postoperative corneal epithelial healing in 21 eye (3.4%), corneal infection in 1 eye (0. 15% ). Six months after operation,corneal haze was 0. 5 degree in 56 eyes(9. 1% ) ,degree 1 in 14 eyes (2. 3 % ) and over 2 degree in 2 eyes (0. 3 % ). Postoperative steroid high intraocular pressure occurred in 7 eyes ( 1.1% ). Twelve months after operation, there was refractive regression 〉 1.00D in 51 eyes (8.3%) ,the increase in astigmatism 〉 1.00D in 19 eyes (3. 1% ),the best corrected visual acuity decreased 1 line in 9 eyes ( 1.4% ). Conclusion LASEK is a safe and effective method for correcting unusual myopic eyes. Yet attention should be paid on the complications during and after operation. With the improvement in operative technique and reasonable drug and with the cooperation of the patients after operation,those complications can be decreased.
