【摘要】：目的观察Nd:YAG激光治疗高危因素白内障患者术后前囊膜收缩的临床效果。方法对2010年12月至2012年11月收集的120例高危因素白内障患者分为试验组(术后3d行激光前囊膜松懈术)和对照组。分别在激光术后立刻(基础值)、1、3、6个月用EAS-1000系统进行前囊膜开口面积测量,同时计算开口面积下降率。并且评价激光术后人工晶体偏移、倾斜、后囊膜混浊及其他并发症。结果在观察的120例患者中,假性囊膜剥脱综合征40例、原发性房角关闭40例、糖尿病视网膜病变40例,激光术后前囊膜开口面积基础值,试验组与对照组比较差异均无统计学意义(P0.05)。激光术后1、3、6个月原发性房角关闭患者,试验组前囊膜开口面积较对照组明显变大(P0.05),而且开口面积减少率明显小于对照组。而假性囊膜剥脱综合征和糖尿病视网膜病变患者,试验组前囊膜开口面积与对照组比较差异无统计学意义(P0.05),但开口面积下降率明显变小(P0.05)。而在人工晶体偏移、倾斜、后发障及其他并发症方面无明显差别。结论白内障术后早期,YAG激光治疗预防前囊膜收缩是安全有效的。
[Abstract]:Objective to observe Nd:. The clinical effect of YAG laser on anterior capsular contraction in patients with cataract with high risk factors after operation. Methods from December 2010 to November 2012, 120 patients with cataract with high risk factors were divided into trial group. (. The patients were treated with laser anterior capsule relaxation 3 days after operation and the control group immediately after laser operation (basic value). The opening area of anterior capsule was measured with EAS-1000 system for 6 months, and the decrease rate of opening area was calculated, and the deviation and tilt of intraocular lens were evaluated after laser surgery. Results among the 120 patients, 40 were pseudocapsular exfoliation syndrome, 40 were primary atrial angle closure, and 40 were diabetic retinopathy. There was no significant difference between the experimental group and the control group in the basic value of the anterior capsule opening area after laser surgery (P 0.05). The patients with primary atrial angle closed at 1: 3 and 6 months after laser surgery. The area of the anterior capsule opening in the experimental group was significantly larger than that in the control group, and the decrease rate of the opening area was significantly lower than that in the control group, while the pseudocapsular exfoliation syndrome and diabetic retinopathy. There was no significant difference in the opening area of anterior capsule between the test group and the control group, but the decrease rate of the opening area was obviously smaller than that of the control group. Conclusion early YAG laser therapy after cataract surgery is safe and effective in preventing anterior capsule contraction.

【正文快照】： 目前,连续环形撕囊(CCC)技术在白内障超声乳化吸除联合人工晶体植入的广泛应用,使手术更安全方便。但过小的CCC可诱发囊袋收缩综合征。囊袋收缩综合征可引起眩光、视力障碍、屈光度改变、对比敏感度下降等临床症状,并影响眼后节的检查和治疗[1-2]。有研究显示,有些眼病如假性
