About The Company
RxSight is a medical device company dedicated to transforming cataract surgery outcomes through the power of adjustability. The company makes the Light Adjustable Lens™ (LAL®), the only FDA-approved intraocular lens (IOL) that can be customized after cataract surgery using ultraviolet (UV) light treatments. Unlike traditional IOLs—which are fixed at the time of implantation—the LAL allows the treating physician to fine-tune the lens prescription after the eye has fully healed. This means patients receive a vision outcome tailored to their actual, post-surgical visual needs rather than a pre-surgical estimate. RxSight (Nasdaq: RXST) works with cataract surgeons and ophthalmologists to bring this personalized approach to vision care. For physicians, the LAL platform provides a clinical differentiation that no other premium IOL can match.
