Purpose. To compare the outcomes of trabeculectomy with and without Healaflow (Anteis S.A, Geneva, Switzerland), a high\nmolecular weight viscoelastic gel, in patients requiring glaucoma surgery. Methods. This was a retrospective, comparative,\ninterventional case-control study. Forty patients formed two matched study groups and were analyzed (trabeculectomy alone\n(control) versus trabeculectomy with Healaflow (study)). Results. The postoperative levels of mean IOP were statistically\nsignificantly lower (P < 0.05) than preoperatively in both groups, for all time intervals. There was no statistical difference, at\nthe end of the follow-up period, between the two groups in the mean values of the IOP (14.9 �± 3.2mmHg for the study group\nversus 14.8 �± 3.3mmHg for the control group). The number of antiglaucoma drugs used in the study group was reduced from a\npreoperative mean of 3.4 �± 0.75 to a 6-month postoperative mean of 0.6 �± 0.8 (P < 0.001) and in the control group from 3.6 �±\n0.59 to 0.55 �± 0.9 (P < 0.001). Conclusions. Although trabeculectomy with Healaflow appears to be a safe procedure, we failed to\nidentify any significant advantages in the use of Healaflow when compared with trabeculectomy alone, at the end of the 6-month\nfollow-up period.
