Sight Sciences Announces Publication of Clinical Data Demonstrating Standalone Effectiveness of the OMNI® Surgical System in Pseudophakic Glaucoma Patients with Uncontrolled Pressure Following a Previous Combination Cataract Stent Procedure

Multicenter Clinical Data from Five US sites Published in International Ophthalmology

• Worldwide, more than one million trabecular microbypass stents have been implanted in combination with cataract surgery.
• Despite glaucoma medications and prior microbypass stenting, target IOP may no longer be achieved over time.
• During 3 to 42 months follow-up, the majority of these standalone study patients treated with OMNI regained IOP control and avoided traditional surgery.

MENLO PARK, Calif., Nov. 03, 2022 (GLOBE NEWSWIRE) — Sight Sciences, Inc. (Nasdaq: SGHT), an eyecare technology company focused on creating innovative solutions intended to transform care and improve patients’ lives, today announced International Ophthalmology has published clinical data demonstrating the safety and effectiveness of the OMNI Surgical System as a minimally invasive, implant-free standalone (not in combination with cataract surgery) glaucoma procedure for pseudophakic glaucoma patients with a history of trabecular microbypass stent implantation (iStent^® or iStent Inject^®) whose pressure is no longer controlled by the bypass stent and IOP-lowering medications.

“Glaucoma is a chronic disease, and most patients will need a variety of treatments over the course of their lives. Compliance with daily glaucoma medications can be low, and depending on the patient and stage of disease progression, some interventions such as bypass stents and/or IOP-lowering medications may run their natural course and no longer control the disease,” said Deepan Selvadurai, MD, a glaucoma specialist and cataract surgeon at Buffalo Ophthalmology in Buffalo, New York, and a clinical investigator and co-author of the study. “The OMNI Surgical System offers a potent implant-free procedure that I have found to be effective and durable in my pseudophakic patients where I had previously implanted trabecular bypass stents at the time of cataract surgery. This study showed that canaloplasty followed by trabeculotomy with OMNI as a standalone procedure in pseudophakic eyes with stents was highly effective in reducing IOP.”

The OMNI Surgical System is an implant-free procedure that uniquely addresses all three known points of resistance in the aqueous outflow system: the trabecular meshwork, Schlemm’s canal, and the collector channels. Because it offers a comprehensive mechanism of action through sequential canaloplasty and trabeculotomy, OMNI surgeons can successfully intervene in the same conventional outflow pathway anatomy when trabecular bypass implants and medications are no longer able to control IOP.

“More than one million eyes have received trabecular microbypass stent implants. Over time, these patients may progress to the point where their IOP is no longer adequately controlled by the implant and/or IOP-lowering medications,” said Paul Badawi, CEO and co-founder of Sight Sciences. “Substantial data supports OMNI’s effectiveness in combination with cataract surgery as well as its standalone use. This important multi-center data shows that OMNI can also help our customers address this large, existing, and growing subset of pseudophakic stented glaucoma patients. We view this as additional validation that OMNI has the unique potential to provide benefit throughout the entire life cycle of glaucoma disease – performed before, during, and after cataract surgery.”

About the OMNI^® Surgical System

The OMNI^® Surgical System is a handheld, single-use therapeutic device for minimally invasive glaucoma surgery (MIGS). It is indicated for canaloplasty (the microcatheterization and viscodilation of Schlemm’s canal) followed by trabeculotomy (the cutting of trabecular meshwork) to reduce intraocular pressure in adult patients with primary open-angle glaucoma.

Through a single clear corneal microincision, OMNI allows surgeons to access all 360 degrees of Schlemm’s canal and treat all three sources of outflow resistance within the eye’s diseased conventional outflow pathway (trabecular meshwork, Schlemm’s canal, and collector channels).

OMNI is indicated by the FDA for canaloplasty (the microcatheterization and viscodilation of Schlemm’s canal) followed by trabeculotomy (the cutting of trabecular meshwork) to reduce intraocular pressure in adult patients with primary open-angle glaucoma. OMNI has a CE Mark for the catheterization and transluminal viscodilation of Schlemm’s canal and the cutting of trabecular meshwork to reduce intraocular pressure in adult patients with open-angle glaucoma.

OMNI should not be used in any situations where the iridocorneal angle is compromised or has been damaged since it may not be possible to visualize the angle or to properly pass the microcatheter. Do not use the OMNI in patients with angle recession; neovascular glaucoma; chronic angle closure; narrow-angle glaucoma; traumatic or malignant glaucoma; or narrow inlet canals with plateau iris or in quadrants with previous MIGS implants.

OMNI received its first FDA clearance in 2017 and is protected by a global patent portfolio including 32 issued patents worldwide.
