iStent placement and verification of function

Steven G. Safran, MD

Show Description +

Here I'm placing an iStent (Glaukos) in a patient's left eye. First, I position the stent parallel and anterior to TM to estimate where I can most easily slide in parallel to Schlemm's canal. After finding that point, I move my hand a bit to the left which angles the inserter a bit so the tip is a bit to the right and at a 10-15 degree angle to pierce TM. I then flatten out and enter Schlemm's canal and slide in parallel with little resistance. One can see significant blanching of the aqueous veins in the region of the stent and well beyond it. When I soften the eye it dilates the aqueous veins and then firming it up creates a wave of blanching starting at the tip of the stent and the moving to the right and well beyond the stent itself suggesting that the function of the stent may go well beyond the direct area of it's placement.
