Outcome of cataract extraction and posterior chamber intraocular lens implantation following glaucoma filtration surgery

Abstract

Purpose To evaluate the outcome of cataract extraction (CE) after glaucoma filtering surgery (GFS). Methods A total of 77 eyes (77 patients) who underwent CE with posterior chamber intraocular lens (PCIOL) implantation following GFS by a single surgeon were reviewed. Main outcome measures were preoperative and postoperative intraocular pressures (IOPs), visual acuities, medications, astigmatism, bleb survival, time of surgical failure, complications, and success rate. Results Mean time interval between GFS and CE was 46.8750.9 months (range, 2-348 months). The mean preoperative IOP was 13.974.7 mmHg (range 3-27 mmHg) and mean postoperative IOP at 3 weeks was 13.675.5 mmHg (range, 6-44 mmHg). The mean follow-up was 19.5720.1 months (range, 1.4-73 months; median 10.6 months). Complete success was achieved in 59 eyes (76.7%). The cumulative probability of complete success was 91.373.7, 82.075.6 and 78.176.5% at the end of 6 months, 1, and 2 years, respectively. Visual acuity before CE was p20/50 in all eyes (100%). Visual acuity at last visit was X20/40 in 33 eyes (42.8 %), 20/50-20/80 in 30 eyes (39.0%), p20/100 in 14 eyes (18.2%). Risk factors identified for qualified success included age at CE460 years, interval of p5 months between GFS and CE, use of preoperative glaucoma medications, and postoperative IOP 419 mmHg within 2 weeks. Conclusions IOP and bleb function was maintained after CE with PCIOL implantation following successful GFS with good visual recovery.

Bleb‐related infection revisited: a literature review

“…; Mandal et al. ). One can extrapolate that the infrequency of BRI after cataract surgery could be credited to induced compromisation of the function of the pre‐existing filtering bleb by the cataract surgery (Chen et al.…”
