iSTAT (Intraluminal Suture Transfixed and Titratable) technique for ligature-free Reversal of long-term drainage implant hypotony.

The iSTAT technique allows for an ab interno revision, titration of flow, and stabilization of the stent in the wall of the tube. The ab interno approach precludes the need for conjunctival incisions, thus maintaining bleb integrity and permitting surgery under topical anesthesia. The intracameral stabilization of the stent in the tube allows for smaller bulbs to titrate the flow without external ligatures.
