AIM:To study theclinical effect of YAG laser techniques for after-cataract.

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.
