GATT Surgery
Clinical Indications and Outcomes
GATT is most commonly combined with phacoemulsification (phaco-GATT), providing simultaneous improvement in visual acuity and IOP control. Candidates: mild-to-moderate open-angle glaucoma (POAG, pseudoexfoliation, juvenile OAG), steroid-induced glaucoma. Outcomes: 30–40% IOP reduction, reduction of 1–2 medications. Hyphema is common post-operatively (blood reflux from Schlemm’s canal) but resolves within 1–2 weeks. Advantages over trabeculectomy: no bleb, faster recovery, conjunctiva preserved.
Why GATT at Suraj Eye Institute?
At Suraj Eye Institute, GATT is offered as a first-line surgical option for suitable open-angle glaucoma patients, combining the benefits of minimally invasive surgery with the anatomical advantage of 360° trabecular meshwork restoration.
Our experienced glaucoma surgeons are skilled in gonioscopic technique and trabecular meshwork anatomy, ensuring precise 360° trabeculotomy. We offer GATT both as a standalone procedure and in combination with cataract surgery to optimize patient outcomes while preserving conjunctival integrity for future surgical options.
