Sight Sciences Introduces the SION™ Surgical Instrument – The First Bladeless Device Used in Goniotomy

MENLO PARK, Calif., August 23, 2022 (GLOBE NEWSWIRE) — Sight Sciences, Inc. (Nasdaq: SGHT), an eyecare technology company focused on developing and commercializing innovative solutions intended to transform care and improve patients’ lives, today announced the launch of SION, a surgical instrument representing a new chapter in goniotomy innovation and practice. Sight Sciences is a leader in minimally invasive approaches to prevalent eye diseases, and SION is an exciting new addition to the company’s portfolio.

The SION Surgical Instrument is a manually operated device used in ophthalmic surgical procedures to excise trabecular meshwork. SION’s bladeless design, micro-engineered and precision manufactured using specialized lasers, excises tissue without cutting. Instead, SION grasps and removes diseased tissue as the surgeon sweeps the instrument around Schlemm’s canal with a single smooth motion.

“Goniotomy is an essential procedure in my glaucoma practice,” said Amir Cohen, MD, MBA, Founder of The Glaucoma Care Center of New Jersey. “As one of the new SION users, I was able to excise and remove several clock hours of diseased trabecular meshwork tissue.”

“I was surprised and impressed at how smooth SION made the goniotomy procedure,” said Arkadiy Yadgarov, MD of Omni Eye Services of Atlanta. “The bladeless design helped the SION tip navigate along Schlemm’s canal without getting stuck into the scleral back wall.”

The bladeless technology of SION was developed with leading ophthalmic surgeons to improve safety and ease of use by eliminating the need to navigate sharp instrumentation within the eye’s anterior chamber and iridocorneal angle anatomy. The design features are intended to drive up the efficiency and completion of the excisional tissue removal procedure.

“The SION Surgical Instrument is an exciting addition to our robust product portfolio and shows our continued dedication to successfully developing and commercializing minimally invasive, interventional approaches to prevalent eye diseases,” said Paul Badawi, Co-Founder and CEO of Sight Sciences. “While our flagship OMNI Surgical System has the broadest and most potent MIGS mechanism of action (trabecular meshwork, Schlemm’s canal, and collector channels) and therefore the largest addressable market, the SION Surgical Instrument enables us to serve the growing goniotomy market subsegment with our existing commercial infrastructure and another best-in-class solution.”

The SION Surgical Instrument is a sterile, single use, manually operated device used in ophthalmic surgical procedures to excise trabecular meshwork. SION should not be used if there is inadequate corneal clarity, or poor visualization of angle structures or in any situations where the anterior chamber angle has been damaged (i.e., from trauma or surgery) or it may not be possible to pass the device through Schlemm’s canal. SION is contraindicated in patients: with angle recession, neovascular glaucoma, chronic angle closure, narrow angle glaucoma, narrow inlets with plateau iris, peripheral anterior synechiae, traumatic, malignant, or uveitic glaucoma; it is also contraindicated in patients who have had previous argon laser trabeculoplasty, ab interno devices implanted in or through Schlemm’s Canal, or prior incisional glaucoma surgery including trabeculotomy, goniotomy.
