Clinical Outcomes and Cost Analysis of PreserFlo versus Trabeculectomy for Glaucoma Management in the United Kingdom.

Purpose: Clinical evaluation and cost analysis of mitomycin-C-augmented PreserFlo MicroShunt versus trabeculectomy.

Design: Retrospective cohort study across 3 teaching hospitals.

Participants: A total of 134 consecutive eyes of 129 patients (70 undergoing MicroShunt, 64 trabeculectomy).

Gonioscopy-Assisted Transluminal Trabeculotomy Following Failed iStent Surgery.

We describe 4 cases of eyes initially treated with phacoemulsification and iStent trabecular microbypass (Glaukos Corporation). These patients subsequently required further surgery and were successfully treated with the removal of the iStent device followed by gonioscopy-assisted transluminal trabeculotomy (GATT), using the iTrack catheter (Ellex Medical Lasers Ltd). Three of the cases had prior first-generation iStent (G1), and 1 had prior second-generation iStent (G2).
