The preliminary results and safety profile for TIGATT are promising and appear at least comparable with previously published results for both GATT and trabectome. Initiating the transluminal trabeculotomy with trabectome clearly exposes Schlemm's canal and facilitates threading the microcatheter into the canal. Additionally, if the 360-degree trabeculotomy cannot be completed because of an incompletely patent Schlemm's canal, the patient will at least have a trabectome ablation that can serve as their glaucoma surgery.
