RxSight - Prediction to Prescription

Beyond Cataract Surgery

Taking Lens Replacement Surgery from Prediction to Prescription

The breakthrough ability to optimize a lens after implantation will transform cataract surgery from a purely predictive method to a dynamic prescription process - RxSight™

Using a special lens material designed by a Nobel Prize winning scientist, the company has developed the first adjustable intraocular lens that allows office-based optimization of vision after lens implantation and healing.

Despite numerous advances

in lens and diagnostic technology, many intervening factors still contribute to unpredictable residual refractive error in current cataract surgery. Only about 50% of patients achieve their targeted distance vision without glasses,1 and a smaller percentage achieve excellent vision at all distances, even with current state-of-the-art multi-focal and other presbyopia correcting intraocular lenses.

RxSight radically changes this paradigm

Instead of prescribing glasses after cataract surgery, physicians can apply the patient’s personalized prescription directly into the adjustable intraocular lens in an office-based procedure. Results from a prior clinical study showed that patients receiving RxSight's Light Adjustable Lens achieved uncorrected vision of 20/20 or better at 6 months postoperatively at approximately twice the rate of patients receiving a standard cataract lens.2

Introducing RxSight’s Light Adjustable Lens

A Personalized IOL Prescription for the Unique Visual Needs of Each Cataract Patient

RxSight’s Light Adjustable Lens technology offers the potential to provide unparalleled visual outcomes to the patient by incorporating an interactive refraction process and the ability to optimize implanted intraocular lens (IOL) based on the patient's visual preference.

During cataract surgery

physicians remove a patient’s cloudy lens and replace it with a clear artificial one. Even though they use the most modern lenses, it is difficult to predict the exact characteristics of the lens necessary to correct vision. Because of this prediction error, along with the potential for lens tilt or shift during the wound healing process, post-cataract surgery patients must often wear glasses for reading or distance vision.

To overcome the prediction problem

RxSight has developed the first intraocular lens that allows for in-office optimization after lens implantation and wound healing. Using a proprietary light treatment that produces modifications in lens curvature, RxSight’s Light Adjustable Lens enables surgeons to precisely reshape the lens based on the visual correction needed to achieve desired vision after cataract surgery.

RxSight’s Light Adjustable Lens can be individualized

for each patient. When the best possible vision is achieved, and validated by the patient, the prescription is “locked in”. Patient participation throughout the normal healing process is integral to define personal vision goals, and effectively directs the precise application of light to create an individualized prescription lens.
