The primary purpose of RxSight lenses, specifically the proprietary Light Adjustable Lens, is to provide highly customized and precise vision correction for patients undergoing cataract surgery or refractive lens exchange. Unlike traditional intraocular lenses that feature a fixed optical power determined entirely before surgery, RxSight lenses are manufactured from a unique photosensitive material. This innovative technology allows eye surgeons to non-invasively adjust and fine-tune the lens prescription using ultraviolet light treatments after the eye has completely healed from the initial procedure, eliminating common post-operative visual surprises and significantly reducing a patient's long-term dependence on eyeglasses or contact lenses.
