Glaucoma treatment with Trabectome, using these surgical steps

Step 1: Scleral Incision
Create a 1.7 mm clear corneal incision with Keratome.
Step 2: Visco-elastic
Inject a small amount of viscoelastic at incision site for easy entry of tip into anterior chamber.
Step 3: Goniolens Placement
Place Goniolens on cornea and verify angle view.
Remove Goniolens and insert tip past the irrigation ports.
Replace Goniolens and activate continuous irrigation.
Advance tip across anterior chamber under direct view.
Step 4: Ablation
Insert tip into Schlemm’s canal anterior to the scleral spur in either a clockwise or counter-clockwise direction.
Depress the foot pedal to activate aspiration and ablation, while advancing the instrument within Schlemm’s canal.
Ablate the trabecular meshwork for approximately one-to-two clock hours (30°-60°).
Step 5: Rotate Tip
Dis-insert tip from Schlemm’s canal and rotate instrument tip toward iris.
Step 6: Ablation
Re-insert tip in the opposite direction from the initial ablation and remove a similar arc in opposite direction.
Step 7: Irrigate and Aspirate
Irrigate and aspirate viscoelastic from anterior segment.
Step 8: Suture
Place one suture across incision. Re-pressurize the globe.
