目的　评价小切口非超声乳化摘出外滤过术后白内障的手术效果。方法　对 5 8例外滤过术后白内障 ( 5级核 )行非超声乳化摘出。结果　 5 8例术后视力均得到提高 ,术前、术后的眼压无显著性差异 ,无并发症发生。结论　对外滤过术后的白内障 ,尤其是高龄患者且为 5级核者 ,行小切口非超声乳化治疗 ,只要方法得当 ,同样可以取得良好效果。 Objective To evaluate the surgical effect of small incision non-phacoemulsification cataract extraction. Methods Fifty-eight extracapsular cataracts (Grade 5) were removed by non-phacoemulsification. Results 58 cases of postoperative visual acuity were improved, preoperative and postoperative intraocular pressure was no significant difference, no complications. Conclusion Cataracts after external filtration surgery, especially in elderly patients with grade 5 nuclei, are treated with mini-incision non-phacoemulsification. As long as the method is correct, the same effect can be achieved.
