【摘要】 目的:观察准分子激光原位角膜磨镶术(laser in situ keratomileusis,LASIK)治疗近视散光的临床疗效。方法:应用鹰视准分子激光治疗系统对120例234眼近视散光进行LASIK手术治疗。随访12mo,比较手术前后的视力、屈光度、散光及其散光轴位的变化。结果:术后随访12mo,裸眼视力≥术前最佳矫正视力(BCVA)者108例213眼(91%),屈光度在±1.00D以内者112例222眼(94.8%),散光残留平均为0.52D。结论:LASIK治疗近视散光效果好,稳定性高,安全可靠。

Abstract
AIM: To observe the effect of the laser in stiu keratomileusis (LASIK) on myopia and myopic astigmatism.
METHODS: LASIK with Allegretto laser system was performed on 234 eyes of 120 patients with myopia and myopic astigmatism. All were followed up for 12 months. Visual acuity, refraction, astigmatism and axis of astigmatism were observed during each visit.
RESULTS: There were 108 cases(213 eyes) whose visual acuity 12 months after surgery was better than the best corrected visual acuity, accounting for 91%.The refractive error after surgery was less than 1.00 in 222 eyes (94.8%). The average residual astigmatism was 0.52D.
CONCLUSION: The correction of astigmatism with LASIK is accurate ,effective and safe.
KEYWORDS: myopia; astigmatism; LASIK
0引言
准分子激光原位角膜磨镶术(laser in situ keratomileusis,LASIK)治疗近视具有安全性、稳定性、可预测性,是目前治疗近视的主流术式;我院200312引进德国鹰视准分子激光治疗系统,至200712已有2800余例近视患者接受LASIK手术,其中有120例合并散光者,观察12mo,效果满意,现报告如下。
1对象和方法
1.1对象 我院200312/200712接受LASIK治疗的近视患者120例234眼,近视度数为1.00~11.00D,散光度数0.50~4.00D,术前裸眼视力0.04~0.3,最佳矫正视力0.5~1.5,其中男52例,女68例,年龄18~40岁。近视及散光稳定2a,停戴角膜接触镜2wk以上。术前检查包括裸眼视力,术前医学验光,眼压,角膜地形图,角膜超声测厚,裂隙灯,Schirmer试验,泪膜破裂时间(BUT),眼底,排除圆锥角膜,视网膜脱离,活动性角膜病变,青光眼,结缔组织病等。
1.2方法 采用德国wavelight公司生产的鹰视准分子激光系统(Allegretto)及法国MORIA公司生产的M2微型角膜刀(130)。常规结膜囊冲洗,皮肤消毒,滴4g/L盐酸奥布卡因滴眼液表面麻醉,铺无菌巾,选择适合负压吸引环,按常规行LASIK术,角膜瓣厚130~160μm,蒂位于上方12∶00方向,切削直径6.0~6.5mm。术后处理:术后1d开始滴用左氧氟沙星滴眼液, 3次/d,共2wk;1g/L玻璃酸钠滴眼液,3次/d,共1mo;1g/L氟米龙滴眼液,第1wk 4次/d,第2wk 3次/d,第3wk 2次/d,第4wk 1次/d,共4wk。术后1d;1wk;1,3,6,12mo进行随访,内容包括远视力、验光、眼压、角膜地形图等检查,注意有无并发症。
2结果
2.1视力 术后随访12mo,所有患者裸眼视力均较术前提高。108例213眼术后裸眼视力≥术前BCVA,占91.0%,7例13眼术后裸眼视力较术前BCVA下降1~2行,占5.6%,术后1~3mo恢复平稳,术后12mo有3例高度近视及散光者视力回退1~2行,所有患者均较满意。
2.2屈光度及散光 术后屈光度在±1.00D以内112例222眼(94.9%),散光残留平均为0.52D,散光轴向平均较术前偏斜2.56°。
2.3并发症 未出现角膜游离瓣,角膜瓣形成不全,角膜瓣移位,层间异物,偏心切削,中央岛等并发症。3例术中结膜下出血,术后1~2wk吸收,术后均有畏光、流泪、异物感症状,3h左右消失,高度近视患者术后1wk~1mo视近模糊。
