Cataract extraction in filtered eyes often leads to decreased outflow and, eventually, to bleb failure. The authors describe a surgical technique that promotes preservation of the filtering bleb.
The authors retrospectively reviewed 19 eyes of 19 consecutive patients who underwent corneal incision phacoemulsification and simultaneous internal revision of the previous filtering bleb.
The mean follow-up time was 13.6 +/- 7.6 months. Visual acuity improved in all patients (89.4 percent achieved 20/40 or better). No significant difference was noted between preoperative and postoperative intraocular pressures and astigmatism. The bleb was preserved in 89.4 percent of the eyes at the time of the last follow-up.
This surgical technique proved to be safe and yielded good results.
在有滤过泡的眼中进行白内障摘除术常常会导致房水流出减少，并最终导致滤过泡失败。作者描述了一种促进滤过泡保留的手术技术。
作者回顾性分析了连续19例患者的19只眼，这些患者接受了角膜切口超声乳化术并同时对先前的滤过泡进行了内部修复。
平均随访时间为13.6±7.6个月。所有患者的视力均有改善（89.4%的患者达到20/40或更好）。术前和术后眼压及散光无显著差异。在最后一次随访时，89.4%的眼的滤过泡得以保留。
该手术技术被证明是安全的，且效果良好。
