Gonioscopy-Assisted Transluminal Trabeculotomy (GATT) is an advanced technique that allows for the opening of the entire circumference of the eye's drainage system via a minimally invasive approach, from the inside out.

How is GATT performed?

Prof. Leshno creates a tiny incision in the cornea and threads a special suture or an illuminated microscopic catheter into the main drainage canal (Schlemm's canal) around the entire circumference of the eye (360 degrees). After the catheter completes the circle, the surgeon gently pulls it inward, an action that cleaves and opens the blocking trabecular tissue along the entire ring.

Efficacy of the Surgery

By freeing all 360 degrees of the drainage canal, a very significant reduction in intraocular pressure is achieved. The surgery is especially effective in patients with open-angle glaucoma and does not involve implanting foreign materials or creating external drainage pockets in the conjunctiva.
