■ Sight Sciences, Inc., launched the manually operated Sion Surgical Instrument, a bladeless, microengineered, precision-manufactured goniotomy device made using lasers to excise tissue without cutting. The tool grasps and removes diseased tissue as the surgeon sweeps the instrument around Schlemm's canal with a single smooth motion, the company said in a news release.

“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.”

Sion’s bladeless technology 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 company noted.
