Background The aim of this study was to compare the outcomes of trabeculectomy with collagen implant versus conventional trabeculectomy for uncontrolled intraocular pressure (IOP). Patients and methods Sixty-eight eyes of 58 patients were randomly selected for trabeculectomy either with Ologen implant (the study group) or without implant (the control group). Preoperative history taking and examinations were carried out. Data including age, sex, glaucoma type, IOP, and numbers of postoperative glaucoma medications were collected. Postoperative IOP, number of postoperative glaucoma medications, and postoperative complications were recorded. Each patient was followed up for 3 years. Results No significant differences were observed between the two groups in terms of preoperative IOP and number of preoperative antiglaucoma medications. Postoperative IOP in the Ologen group was significantly lower than that in the control group at all follow-up visits; the mean IOP in the Ologen group was 12.88±2.37 mmHg and that in the control group was 17.26±2.72 mmHg (P=0.006). The mean number of antiglaucoma medications (0.61±0.15) in the Ologen group was significantly lower than that in the control group (1.48±0.19) at last visit (P<0.001). There were no statistically significant differences between the two groups as regards postoperative complications as observed in this study. Conclusion Trabeculectomy with Ologen showed significant advantages over trabeculectomy alone in terms of IOP. Large sample size is needed to confirm the safety and long-term outcome of trabeculectomy with Ologen.
