Laser Assisted NPDS Procedure
The IOPtiMate™ system and laser-assisted procedure enable the controlled use of a CO2 laser to thin the scleral tissue at the Schlemm's Canal zone without full scleral penetration, facilitating percolation of fluid through the remaining membrane and the reduction of IOP. As an all-inclusive platform for laser-assisted NPDS, the IOPtiMate™ is designed to achieve functional, simple, safe, reproducible and optimal results from surgery, with all the advantages of NPDS and minimal complications. This approach may minimize recovery time and allow for the surgeon to achieve surgical competence rapidly compared to existing systems.
The IOPtima surgical procedure can be performed at an out-patient clinic in less than an hour, and comprises the following steps:
- Flapping. Under local anesthesia, a standard scleral flap is performed.
- Ablation. The surgeon uses the micromanipulator and the scanner to determine the designated area of treatment, and then uses the laser beam to ablate a scleral tissue layer of several microns in thickness every cycle. The procedure is repeated until desired aqueous percolation is achieved.
- Percolation. Once the scleral tissue has been adequately thinned, percolation can occur through the remaining membrane. Because the CO2 laser is effectively absorbed by liquid, the procedure is self-limiting by percolation, thus preventing further ablation and the risk of perforation. Ceasing the ablation at the time when functional percolation is achieved promotes reproducible effectiveness as any further ablation and the risk of perforation is inherently inhibited.
- Completion. The surgeon performs a standard closure of the flap.
