Purpose: To determine effectiveness and influence of fornix vs. limbal based conjunctival flap approach in phacotrabeculectomy with mitomycin C.
Method: Prospective study of phacotrabeculectomy with IOL implantation and intraoperative mitomycin C was performed in 16 patients with bilateral cataract and POAG. We have randomly assigned one eye of each patient to the fornix based or limbal based flap group.
Results: We have observed a significant decrease in IOP in both groups (p< 0.01). There was no statistically significant difference in the number of antiglaucoma medications between groups after 16 months of follow-up. The mean time of the procedure was shorter in the fornix based group. We have also observed early leakage of the bleb in the fornix based group more frueqently.The most frequent complications were fibrin exudation, pupillary membrane formation and capsule opacification.
Conclusions: The choice of conjunctival flap in phacotrabeculectomy does not influence the final outcome of the surgery. In fornix based conjunctival flap approach surgical time is shorter, but there are more frequent early bleb leakages.
