Background And Objective:
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.
Patients And Methods:
The authors retrospectively reviewed 19 eyes of 19 consecutive patients who underwent corneal incision phacoemulsification and simultaneous internal revision of the previous filtering bleb.
Results:
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.
Conclusions:
This surgical technique proved to be safe and yielded good results.
