MicroPulse P3® Delivery Device for Non-Incisional Glaucoma Treatment

sponsored by Iridex

The Iridex MicroPulse P3® Delivery Device is a fiberoptic handpiece used with the Iridex Cyclo G6® Laser System to perform MicroPulse Transscleral Laser Therapy (TLT) – a nonincisional procedure that substantially reduces intraocular pressure for a broad range of glaucoma types including primary openangle, closed-angle, and refractory glaucomas.

Since 2015, more than 120,000 patients have been treated globally with MicroPulse TLT. In the USA, the procedure is performed in 35 of the top 39 ophthalmology hospitals (1).

Earlier this year, Iridex revised its design of the MicroPulse P3 device to enhance stability, coupling, visualization, and fit. The enhancements include a smooth, scleral-matching footplate curvature to increase stability; a recessed fiber tip with an added fluid channel to enable constant fiber immersion in fluid to improve light coupling to the tissue – critical for the success of the procedure; an elongated stem to improve visualization of the treatment area and to function as a speculum if needed; and a reduced footplate for ease of placement in small eyes.

Overall, the revised MicroPulse P3 device creates a more ergonomic-friendly handpiece to perform MicroPulse TLT – a versatile therapy to use prior to, in conjunction with, or following all other glaucoma treatment options.
