First International MIGS Data for the Omni Surgical System Presented at ESCRS

Sight Sciences announced clinical results from the first study of the Omni Surgical System in glaucoma patients were presented at the European Society of Cataract and Refractive Surgery (ESCRS). Findings from the pilot study suggest the Omni Surgical System, which is dually indicated in Europe for the sequential ab-interno procedures of microcatheterization and transluminal viscodilation of Schlemm’s Canal followed by transluminal trabeculotomy, may provide a favorable safety profile and significant long-term reductions in IOP and IOP-lowering medications.

The pilot study included 24 eyes from 19 consecutive patients with mild to moderate primary open-angle glaucoma (POAG) who were treated with the Omni Surgical System. The study was conducted at the Ophthalmology Clinic Postgraduate Centre of Medical Education in Warsaw, Poland by Professor Grabska-Liberek, recent President of the Polish Ophthalmology Society.

Key findings include:

  • Canal viscodilation followed by trabeculotomy using the Omni Surgical System with or without cataract surgery resulted in substantial IOP reduction and IOP-lowering medication reductions at 18 months.
    • Mean 40 percent IOP reduction (21.4 mmHg to 12.8 mmHg) at 18 months
    • Mean 41 percent medication reduction (2.9 meds to 1.7 meds) at 18 months
  • The most common adverse events were IOP-spikes (nine eyes), hyphema (six eyes) and fibrin in the anterior chamber (five cases), all of which resolved in the first week after surgery.
  • No eyes required additional surgical intervention to control IOP over the 18-month follow-up period

“We are pleased to announce the first presentation of long-term clinical data on the Omni Surgical System. With its unique capability to perform two sequential outflow procedures (canal viscodilation and trabeculotomy), Omni is the only device that can target all three sources of resistance in the conventional outflow pathway. The clinical findings of this first Omni study suggest a durability and consistency of IOP lowering and medication reduction when all three sources of outflow resistance are targeted sequentially,” Ingrid Kane, MD, Vice President of Global Medical Affairs of Sight Sciences, said in a company news release. “While larger, additional studies are needed and ongoing, these exciting first clinical results from one of the first surgeons to perform the two sequential Omni procedures follow just behind the long-term clinical data publications on Omni’s two predicate procedures: VISCO360/viscodilation and TRAB360/trabeculotomy. With several retrospective and prospective clinical studies ongoing and others being planned, we continue our commitment to building a very robust clinical data set on Omni that we expect will further reinforce the clinical benefits of targeting all three sources of resistance in the conventional outflow pathway.”

Study Investigator Professor Grabska-Liberek added, “The Omni Surgical System is a promising new surgical glaucoma technology that I have been using to successfully intervene prior to considering more invasive incisional surgeries such as those using the subconjunctival space for filtration. Omni is the only technology that allows 360 degrees of canal viscodilation followed by 360 degrees of trabeculotomy all via an ab-interno approach. Using just a single corneal incision to target the conventional outflow pathway, the OMNI procedure should be intuitive to both cataract surgeons and glaucoma specialists.”
