Nd:YAG激光两种不同方法治疗后发性白内障的疗效对比观察

Clinicai observation on Nd:YAG laser in the treatment of patients with after-cataract by different preoperative managements

目的探讨Nd:YAG激光以不同处理方式治疗后发性白内障的效果。方法对62例(62眼)后发性白内障患者随机分为A组(31例)和B组(31例):A组在表面麻醉后放置接触镜下行激光治疗;B组在不需表面麻醉不放置接触镜情况下直接行激光治疗。所有患者术后随访6～12个月。结果 62例62眼术后视力均有不同程度提高,增视率为100%;A组、B组术后视力与术前比较差异均有统计学意义(P均<0.01);激光治疗时间B组(4.62±1.54)min较A组(7.42±1.85)min短(P<0.01);两组术后未见严重并发症发生。结论采用不表麻不放置角膜接触镜直接行Nd:YAG激光后囊膜切开术治疗后发性白内障,操作简易,疗效确切。

Objective To study the effects of Nd ： YAG laser with different preoperative managements for al- ter-cataract. Methods Sixty-two cases （62 eyes ） with after-cataract were divide into two groups and treated with Nd ： YAG laser. Surface anaesthesia and contact mirror were used before taking laser treatment under preset lens in group A ;laser treatment was directly taken without management in group B. The follow up time was 6 to 12 months. Results Visual acuity improved at different levels after Nd： YAG laser treatment in 62 eyes of 62 cases, the im- proved rate of visual acuity was 100%. There were significant differences of visual acuity in A group and for group B between re-operation and post-operation （P all 〈0. 01 ）. The time of laser treatment in group B （4. 62 ± 1.54） minutes was shorter than that in group A（7.42 ± 1.85 ） minutes, there was signifaeant difference between the two group （ P 〈 0.01 ）. No serous complication was found in both two group postoperatively. Conclusion Nd ： YAC laser with- out surface anaesthesi and contact mirror is a simple and reliable treatment for after-cataract too.
