Advances in Nonimplant MIGS
Author(s):
A panelist discusses how differences in viscodilation devices—particularly the presence or absence of pressurized viscoelastic delivery—impact IOP outcomes in MIGS, highlighting the advantages and trade-offs of Omni, iTrack Advance, and Via360 based on surgical goals and ease of use.
Device Comparison: Pressurized Viscoelastic Delivery in MIGS
This discussion compared viscodilation devices used in MIGS, focusing on Omni, iTrack Advance, and Via360. While Omni is widely used and user-friendly, it lacks pressurized viscoelastic delivery, which studies have shown yields better IOP reduction. iTrack Advance and Via360 both provide pressurized delivery via a 360 ° catheterization of the Schlemm canal. iTrack offers a lighted tip for guidance but involves a more complex setup, while Via360 is simpler to use and delivers a high-pressure, multiport flow, resulting in more immediate blanching of perilimbal vessels. Device choice ultimately depends on surgical preference, patient-specific needs, and desired control over viscoelastic flow and IOP outcomes.
