About the Company

RxSight

Post-implantation adjustable intraocular lens system

RxSight develops medical devices for vision correction in cataract surgery. Its flagship product is the Light Adjustable Lens (LAL), an intraocular lens that can be adjusted after implantation using a Light Delivery Device (LDD) to achieve the best possible vision. How it works: after the LAL is implanted, doctors use controlled light exposure via the LDD to fine-tune the lens power post-operatively, allowing precise refractive outcomes before finalizing vision. How RxSight differs from competitors: instead of relying on fixed lenses, it offers an adjustable lens system that enables post-operative customization, paired with a dedicated delivery device and support for ophthalmologists and clinics to optimize patient results. Its goal is to improve quality of life for patients with cataracts and corneal astigmatism by delivering superior, individualized visual outcomes and expanding access to precise vision correction in the cataract market.
