Abstract Details

Purpose:

To evaluate the efficacy and safety of ABiC in patients with primary open-angle glaucoma (POAG) in combined surgery.

Setting:

Augencentrum Köln-Porz, Germany

Methods:

23 eyes of 27 patients (mean age, 77 years; range, 66-83 years) underwent phacoemulsification and ABiC using the iTrack™ 250-micron microcatheter (Ellex Medical Lasers Pty Ltd, Adelaide, Australia) to circumferentially viscodilate and intubate Schlemm’s canal without placement of a tensioning suture. 4 pseudophacic eyes were operated as stand alone procedure.The primary endpoints were mean intraocular pressure (IOP) and

Results:

Mean IOP reduced from 19,76 ± 5,22 mm Hg preoperatively to 14.5 ± 2,82 mm Hg (n=27), 14,0 ± 2.78 (n=21), 15,53 ± 2.8mm Hg (n=24), 14,58 ± 3,76 (n=22) ,14,25 +-3,11 mmHg at 6 ,12, 24,36 and 48 months postoperatively. The pre-OP IOP was measured without a wash-out phase. The mean number of medications was reduced from 1,93 preoperatively to 0.3, 0,33;0,4; 0,59; and 0,87 at 6,12,24,36, and 48 months. One third of the patients was operated with AbiC due to complete intolerance to medication under well controlled IOP conditions. A limited descemetolysis near the limbus during the dilatation of Schlemm`s canal occurred in one patient. No other adverse events were reported.

Conclusions:

The findings from this study indicate that ABiC lowers IOP and medication dependency. Long-term follow-up in a larger patient cohort is required to confirm the efficacy of this minimally-invasive and implant-independent glaucoma procedure.
