The G-Probe^® Delivery Device performs Continuous-Wave Transscleral Cyclophotocoagulation (CWTSCPC) to lower IOP through selective ablation of the ciliary processes. This simple, yet effective repeatable procedure can be performed in the office, operating room, or in conjunction with other procedures, like cataract surgery.

SURGICAL GUIDE

Placement

Hold the G-Probe® Delivery Device parallel to the visual axis with the shorter edge of the footplate firmly between the anterior border and the middle of the limbus. Laser delivery is transscleral.

Application

Successive applications are spaced one-half the width of the G-Probe footplate apart by aligning a side of the probe over the indented center of the adjacent application.

Treatment

Administer 18-21 laser applications per treatment session over 270° (three quadrants, six or seven applications per quadrant), usually omitting the temporal quadrant.

Parameters

This array of treatment parameters has been called the “slow coagulation” technique and has proven effective for most eyes.3 Note that these treatment parameters are suggested by IRIDEX and are based on recommendations by experienced clinicians. Ultimately, it is the physician’s responsibility to determine appropriate treatment parameters for each case. Cautions: Keep the G-Probe tip immersed in a viscous liquid coupling agent (and the eye surface moist) and apply consistent pressure throughout the CWTSCPC treatment. Do not treat over sites of previous trabeculectomies.

Patients to Consider

• The patient is not a surgical candidate for filtration surgery
• The patient has failed prior filtration surgery and is expected to fail further filtration surgery
• The patient has a secondary glaucoma in which failure is a likely outcome of filtration surgery (e.g., neovascular, inflammatory, postpenetrating keratoplasty, postscleral buckling).
• The patient has lost ambulatory level vision and is being treated with cyclophotocoagulation for comfort or to prevent further visual loss.

PHYSICIAN TESTIMONIALS

	You can really consider TSCPC in almost all glaucoma situation, even malignant glaucoma. It is not just relegated to end-stage treatment anymore. Dr. Jeffrey Kammer | Nashville, TN | Vanderbilt Eye Institute
	TSCPC is a surgery that can be done before or after any other surgery. It is very versatile from that standpoint. Dr. Nathan Radcliffe | New York, NY | Weill Cornell Medical College
	Recovery with TSCPC is much more rapid and the postoperative care much less involved than with someone who has had an incisional glaucoma case in a surgical center. Dr. Steven Vold | Springdale, AR | Vold Vision, PLLC
