Sight Sciences Introduces the First Bladeless Device Used in Goniotomy

Sight Sciences has announced the launch of SION, the first bladeless device used for goniotomy. In ophthalmic surgical operations, the SION is manually operated and used to remove trabecular meshwork.

Bladeless SION excises tissue without cutting it thanks to micro-engineered manufacturing processes and specialized lasers. Instead, as the surgeon sweeps the probe through Schlemm's canal in a single fluid motion, SION grasps and eliminates diseased tissue.

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

"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 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," Paul Badawi, Co-Founder and CEO of Sight Sciences, said in a company news release.

"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."
