MICS + trabeculectomy a good match

Microincision cataract surgery (MICS) combined with trabeculectomy provides a one-year intraocular pressure (IOP) control comparable to that found with trabeculectomy and separate temporal clear corneal phaco, according to the results of a study by Dr Bayer and colleagues from the Ankara School of Medicine, Turkey.

A total of 63 eyes with co-existing cataract and glaucoma were randomly assigned to receive mitomycin-C (MMC) trabeculectomy in the superior quadrant combined with phaco and foldable intraocular lens (IOL) implantation through a separate, temporal, clear corneal incision (2-site group) or MMC trabeculectomy in a superior quadrant combined with MICS followed by IOL implantation from the trabeculectomy incision.

Mean preoperative IOP was 28.1±7.1 mmHg and 27.7±6.5 mmHg in the 2-site and MICS groups, respectively. At six-months postoperatively, mean IOP was 14.9±4.3 and 14.3±3.8 mmHg, respectively (p=0.7) and at 12 months, 15.6±3.3 and 15.1±3.1 mmHg, respectively (p=0.5). Postoperative astigmatic change and complications were comparable between the groups.

Dr Bayer concluded that MICS with trabeculectomy and trabeculectomy with separate temporal clear corneal phaco provide comparable IOP control at one-year.
