【摘要】：近视(myopia)是人类的一种常见眼病,其发病率各国报道不一,一般在10%-30%,若以平均25%计算(美国眼科年会1989年估计全世界有近1/4的人患近视眼),则在50多亿人口中,近视眼患者至少有15亿多,由于人种及文化特点,我国已被公认是近视眼高发病率国家之一。近视眼的防治一直是全世界医学界期望攻克的难题,其矫正方法通常分为三类:①镜片矫正:包括框架眼镜、角膜接触镜;②角膜屈光性手术:放射状角膜切开术(radialkeratotomy,RK)、准分子激光切削术(photorefractive keratectomy,PRK)、准分子激光原位角膜磨镶术(Laser in situ keratomileusis,LASIK)等;③眼内手术:透明晶体摘除术、有晶体眼的人工晶体植入术等。近年来各种屈光手术的发明、创新和发展已成为近视眼治疗的研究热点,目前,临床上应用最广泛的屈光手术为LASIK。本研究的目的是观察LASIK手术矫正近视、散光的近期效果,选择了2004年6月~8月在吉林大学第一医院视光中心接受LASIK治疗的57名患者、114只眼,根据等效球镜度(sphericalequivalent,SE)分为低中度、高度两组,进行术后1天、7天、1月、3月的随访,对裸眼视力(uncorrected visual acuity,UCVA)、SE、裂隙灯、角膜地形图等进行检测分析。结果显示:(1)两组患者UCVA较术前有显著提高;(2)术后3月两组患者裸眼视力达1.0及以上者分别为96.67%、92.59%。(3)术后3月两组患者屈光力在±1.0D以内的分别为96.67%、85.19%。(4)两组患者术后均无夜间视力下降、眩光及其他严重并发症出现。根据结果可以看出,LASIK手术治疗近视、散光的近期临床效果好,较大光区切削和良好的中心定位可有效减少手术并发症。
[Abstract]:Myopia (myopia) is a common eye disease in humans. The incidence of myopia varies from 10 to 30%. If calculated at an average of 25% (in 1989 the annual meeting of American Ophthalmology estimated that nearly 1/4 people in the world had myopia, more than 1.5 billion of the more than 5 billion people had myopia. Because of the characteristics of race and culture, China has been recognized as one of the countries with high incidence of myopia. The correction methods are usually divided into three types: 1: lens correction: frame glasses, cornea contact lens; 2Corneal refractive surgery: radial keratotomytomytomy (RK). Excimer laser ablation (PRK). Laser in situ keratomileusism, laser in situ keratomileusis, et al. 3 Intraocular surgery: transparent lens excision, intraocular lens implantation with lens, etc. In recent years, the invention, innovation and development of various refractive surgery have become the research focus of myopia treatment. LASIK is the most widely used refractive surgery in clinic. The aim of this study was to observe the short-term effect of LASIK surgery on myopia and astigmatism. #number0# eyes of 57 patients treated with LASIK from June 2004 to August in the Optometry Center of the first Hospital of Jilin University were selected. According to the equivalent spherical equivalent SES, the patients were divided into two groups: low, moderate and high, followed up 1 day, 7 days, January, March. Uncorrected visual acuity (UCVA), slit lamp for uncorrected visual acuity. The results showed that the UCVA of the two groups was significantly higher than that before operation. (2) on March, the uncorrected visual acuity of the two groups was 96.67% or better. On March, the refractive power of the two groups within 卤1.0D was 96.67 and 85.19.4respectively) there was no nocturnal visual acuity decrease in both groups. According to the results of LASIK operation for myopia, the clinical effect of astigmatism is good in the near future, and the larger light area cutting and the good central location can effectively reduce the complications of the operation.
