Abstract Details


The aim of the study is to assess the changes in the intraocular pressure, endothelial cell density, visual acuity and refractive changes (induced astigmatism), and per-operative complications in patients undergoing Phaco-TRAB (Group 1) and SICS-TRAB (Group 2) for coexisting primary open angle (POAG)/ angle closure glaucoma (PACG) and cataract.


The study was conducted in the Glaucoma clinic of Aravind Eye Hospital, Coimbatore in India.


Sixty eyes of 60 patients undergoing either phaco-trab or small incision cataract surgery combined with trabeculectomy were included in the study. This was a nonrandomized comparative study the patients chose the type of surgery. Primary outcome were changes in intraocular pressure and endothelial cell (EC) density and secondary outcomes were astigmatic changes after surgery (induced astigmatism) and intraoperative and postoperative complications at 1, 3 and 6 months.


Twenty three patients (82.1% in group 1 and 88.4% in group 2) in both groups obtained a good visual outcome of 0 to 0.2 at 6th month. The mean IOP at 6 months was 13.68(SD 3.08) mmHg in Group 1 and 16.0(SD 4.96) mmHg in Group 2 (p=0.04). The mean surgically induced astigmatism was 0.95(SD .078) D in group 1 and 1.03(SD 0.75) D in group 2 at 6 months (p=0.71). The mean EC loss was 13.97% in group 1 and 10.56% in group 2 and (p=0.05). Perioperative complications were more in group 2 than Group 1


At the end of 6 months Phacotrabeculectomy offers a better IOP control and visual rehabilitation with fewer complication albeit with a marginally greater loss of endothelial cells.
