RxSight® Light Adjustable Lens™

The future is here—and it’s adjustable.

Imagine if cataract surgery results were adjustable to meet patients' unique needs rather than fixed by pre-manufactured IOL power. The Light Adjustable Lens™ (LAL™/LAL+™) is the only IOL that allows lens power adjustments within the eye after cataract surgery. Through precise UV light treatments, the lens power of the Light Adjustable Lens is fine-tuned, offering patients a truly customized visual experience.


The Light Adjustable Lens has transformed cataract surgery by shifting crucial decisions regarding final lens power to the more ideal post-surgery period. This approach allows for unparalleled precision, as it accounts for lens shift and refractive changes that can occur during the healing process to achieve the best possible outcomes.



The innovative Light Adjustable Lens represents a departure from the usual practice of selecting a pre-manufactured lens power before surgery to predict a patient’s post-surgery visual outcome. The accuracy of vision achieved with the postoperative adjustability of the Light Adjustable Lens compared to traditional premium IOLs has been demonstrated in clinical studies.


The Light Adjustable Lens is a versatile premium lens that surgeons worldwide are finding is customizable for many types of patients. Throughout the adjustment process, Light Adjustable Lens patients are engaged and participate in their care in a way other lenses can’t offer.

This truly customized approach has led to outcomes they and their doctors are excited about. Almost daily, we add to the list of clinics worldwide that are successfully integrating the Light Adjustable Lens into their workflow and finding that it is a transforming technology for their practices and their patients.

How the Light Adjustable Lens Works

The Light Adjustable Lens is implanted using a standard cataract procedure. Patients then experience their vision and surgeons can adjust the lens over a series of treatments to ensure each patient achieves vision that matches their lives. Each adjustment is a UV light treatment performed by the Light Delivery Device™ (LDD™) that corrects refractive error and dials in optimized vision.

The LAL and the LAL+ are built on the same platform. The LAL+ has a modified aspheric anterior surface that creates a small continuous increase in central lens power, which is designed to slightly extend the depth of focus.
