Irrigation/Aspiration, Now Available in a MIGS Device Near You

Angle-based glaucoma procedures are among the most specialized cases in ophthalmology. While Minimally Invasive Glaucoma Surgery (MIGS) created a novel path for comprehensive ophthalmologists to surgically treat glaucoma, these procedures require new techniques and training. New surgical landscapes, (in some of the smallest tissue structures of the eye) can cause stress even for the most skilled ophthalmologists. TrabEx Pro is an innovation that provides confidence in surgery and minimizes the potential obstacles of the MIGS space.

Introducing TrabEx Pro
 

MicroSurgical Technology (MST) aims to simplify angle- based surgical procedures with the latest addition to its line of glaucoma solutions. TrabEx Pro is a new device designed for the removal of diseased Trabecular Meshwork (TM) that incorporates Irrigation/Aspiration (IA). The device features laser- honed, serrated blades that are configured in a trapezoidal orientation. The cutting edge of the blades start narrowly opposing each other and progressively widen farther up the blade allowing for the potential to make variable excisions for each section of tissue, instead of the one- size-fits-all approach of other goniotomy blades.

The blade-head is custom engineered to be sharp where it contacts trabecular meshwork, yet protective of the surrounding tissue. The rounded, distal foot provides gentle contact with Schlemm’s Canal while the curvature of the posterior heel guides the surgeon around the arch of the eye for a smooth surgical sweep.

Each aspect of the device handle has been carefully molded to provide ultimate user comfort. The weight distribution and rotational grooves are designed to provide maximum surgeon comfort and control intraoperatively, while the directional indicator gives tactile input for blade direction, further enhancing user confidence and control when using the device.

Visibility, my old friend
 

Of the greatest advancements in anterior segment surgery in recent decades, the most notable have been around improving chamber stability and visibility during surgery. TrabEx Pro makes the connection between those legacy advancements and novel MIGS technology. The device connects to any phacoemulsification platform and incorporates IA to maintain high chamber stability and visibility during surgery. TrabEx Pro features a flexible silicone infusion sleeve to accommodate incisions ranging from 2.2 to 2.4mm and facilitate a smooth transition in combined cataract and goniotomy procedures.

The history and the future
 

First described in the 1930’s, then redesigned in 2006 with Trabectome for adult patients, goniotomy has a longstanding history in the treatment of glaucoma. Clinically, it has been evaluated in adult and pediatric patients, with cataract surgery or as a standalone procedure, as well as open-angle, narrow-angle, pseudoexfoliative, pigmentary, mild, moderate, and severe glaucoma. MST looks to further contribute to the extensive body of clinical literature on goniotomy moving forward. They are actively engaging and seeking opportunities to conduct research on TrabEx Pro.

TrabEx Pro is now commercially available in the US.
