Bringing the Power of Adjustable Outcomes to Light

The World's First Adjustable IOL

An Innovative Way to Deliver Premium Cataract Surgery

RxSight® has developed the first and only FDA-approved intraocular lens (IOL) that can be adjusted postoperatively (postop) to improve uncorrected visual acuity. The Light Adjustable Lens™ is implanted during a standard cataract procedure. However, visual outcomes are not dependent on the prediction of SIA, ELP, individual healing, or sophisticated equipment. Instead, vision optimization takes place after the Light Adjustable Lens is in its final position and the patient’s eye has healed, overcoming the limitations of preoperative (preop) and intraoperative prediction processes.


How the Light Adjustable Lens works

The Light Adjustable Lens is made of a special photosensitive material that absorbs ultraviolet (UV) light. Using a proprietary light treatment—the Light Delivery Device (LDD)—to produce modifications in lens curvature, the Light Adjustable Lens enables surgeons to precisely reshape the lens based on the visual correction needed to achieve the patient’s desired vision after cataract surgery.

To perform the light treatments, the patient is refracted and the refractive error is entered into the office-based LDD. The LDD delivers UV light in a precisely programmed pattern to induce a predictable change in the shape and refractive properties of the lens. Between 1 and 3 adjustments are possible, enabling a fully interactive process of designing and trialing the patient’s final vision. A subsequent lock-in exposure is delivered to the implanted Light Adjustable Lens to stabilize the lens power.

Following surgery, patients are provided with UV protective glasses to wear at all times to help protect the Light Adjustable Lens from indoor and outdoor sources of UV light. The patient may discontinue wear of the UV protective glasses 24 hours after the final light treatment has been completed.

ELP = effective lens position; SIA = surgically-induced astigmatism.

Postop adjustability vs preop predictions

With the Light Adjustable Lens, the preop discussion with patients focuses on cataract surgery and the adjustable IOL. You will not need to spend increasing amounts of preop chair time describing the patient’s refractive error, the various types of IOLs, the patient’s refractive options and targets, and how various IOL choices will impact quality of vision—all difficult and stressful decisions for patients.

Despite modern cataract surgery technologies, residual refractive error is still common due to variables of incision healing and the final effective lens position. Instead of relying on preop predictions or postop LASIK enhancements, the Light Adjustable Lens enables physicians to adjust the stabilized postop refraction. For the first time, patients can preview different visual outcomes and select a customized prescription after their surgery, giving them greater peace of mind.

FDA approved for cataract patients with preexisting astigmatism

FDA approval was based on results of a U.S. randomized, pivotal study that evaluated the safety and effectiveness of the Light Adjustable Lens and LDD compared to a commercially available monofocal lens in 600 eyes with preexisting astigmatism.¹

The Light Adjustable Lens and Light Delivery Device system are indicated for the reduction of residual astigmatism to improve uncorrected visual acuity after removal of the cataractous natural lens by phacoemulsification and implantation of the intraocular lens in the capsular bag in adult patients:

  • With preexisting corneal astigmatism of ≥ 0.75 diopters
  • Without preexisting macular disease

The system also reduces the likelihood of clinically significant residual spherical refractive errors.
