方法：后发性白内障患者203例224眼，经详细眼科检查，散瞳后，采用国产Nd：YAG激光(波长1 064μm)进行激光治疗，激光瞄准光聚焦于后囊膜表面，环形切开后囊膜，切开直径约3～4mm。激光后定期复查。对治疗前后视力，采用SPSS 11.0统计软件进行统计分析比较。

结果：本组患者均为一次性激光切开成功，成功率为100%； 视力均获提高，经统计学处理，治疗前后视力有显著性差异(P<0.01)。

结论：Nd：YAG激光是治疗后发性白内障安全有效的方法。

METHODS: Totally 203 patients 224 eyes with after-cataract were include,d after detailed ophthalmologist exams and mydriasis, they were managed by Nd:YAG laser(wavelength:1064μm). Laser aiming light was focused on posterior capsule. Posterior circular capsulotomy was used, and the diameter was about 3-4 mm. After the laser treatment, patients were checked regularly and SPSS 11.0 statistic software was used to deal with the vision before and after the treatment.

RESULTS: The posterior capsules were all successfully opened by once laser, and the success rate was 100%. Their visions were all improved. The vision before and after the treatment had significant differences by statistical disposal(P<0.01).

CONCLUSION: Nd:YAG laser is safer and effective in treating after-cataract.
