研究设计:

非随机对照试验 

Study design:

Non randomized control 

研究目的:

分析白内障超声乳化术中用三种不同方法(即: Toric IOL植入、飞秒激光制作角膜松解切口、手术刀制作角膜松解切口)矫正低度角膜逆规散光(0.75D~1.50D)的临床效果,并分析其临床意义。  

Objectives of Study:

Compare and analyze the effect and clinical results of three different methods ( Toric IOL implantation, femtosecond laser-assistant cataract surgery(FLACS) with astigmatic keratotomy , limbal relaxing incision by scalpel)for correction low degree against-the-rule(ATR) corneal astigmatism(0.75D~1.50D) during cataract surgery.

Description for medicine or protocol of treatment in detail:

 

纳入标准:

确诊为年龄相关性白内障;合并低度角膜逆规散光(0.75D-1.50D);Pentacam HR(德国Oculus公司)、iTrace(美国Tracey公司)、IOL-Master500(德国Zeiss公司)三种设备测量角膜曲率(simK)及轴向稳定性好的患者(三种设备测量的散光轴向差异≤10°,同一设备三次重复检测光轴向差异≤5°,散光值差异≤0.5D);角膜球差范围在0.20~ 0.50um的患者;所选人工晶体为AcrySof IQ Toric IOL或AcrySof IQ IOL;年龄范围在45~75岁的患者;

Inclusion criteria

1. Diagnosed as age-related cataract;
2. Combined with low degree ATR astigmatism (0.75D-1.50D);
3. Three devices (Pentacam HR (Germany Oculus company) iTrace (America Tracey company) IOL-Master500 (Germany Zeiss company)) were used to measure the curvature of the cornea (simK) and the axial direction of the cornea, patients with good stability were selected (the difference of axial direction measured by the three devices is less than or equal to 10the axial direction difference among the 3 repeated measurements by the same device is less than or equal to 5, difference of astigmatism value less than or equal to 0.5D);
4. Patients with corneal spherical aberration ranging from 0.20 to 0.50 um;
5. The selected intraocular lens is AcrySof IQ Toric IOL or AcrySof IQ IOL;
6. Patients aged from 45 to 75.

排除标准:

不规则的角膜散光;术眼的α角或Kapple角>0.5mm者;泪膜不稳定的患者;合并有影响视力的其它眼部病变;手术过程中发现悬韧带功能差、后囊破裂的患者;排除眼轴长于28mm的患者;不能配合检查,和不能按时随访的患者。

Exclusion criteria:

1. Irregular corneal astigmatism;
2. Operative eyes with angle of alpha or Kapple>0.5mm;
3. Those wih instable tear film;
4. Combined with other eye disease affecting visual acuity;
5. Patients found with poor suspension ligament function and posterior capsule rupture during operation;
6. Patients with eye axial longer than 28mm;
7. Patients unable to cooperate for the examination and follow-up on time.
