Light Adjustable Lens

The Light-Adjustable Lens (LAL) manufactured by RxSight™ is the first and only cataract lens implant that can be customized after cataract surgery. This customization helps deliver superior visual outcomes that non-adjustable IOLs simply cannot match. In a study of 600 subjects, those who received the Light Adjustable Lens followed by adjustments were twice as likely to achieve 20/20 distance vision at 6 months without glasses as those who received a standard monofocal IOL. This technology can also allow patients to have the best possible corrected vision for distance in their dominant eye and if they wish for independence from reading glasses, the surgeon can adjust their non-dominant eye for reading vision.

Designed by a Nobel Prize winning scientist Dr. Robert Grubbs of California Institute of Technology, the LAL is a three-piece silicone lens that is implanted just like a monofocal lens implant, except the LAL is made with a special photoreactive silicone, permitting surgeons to adjust a patient’s prescription after implantation by using a specialized Ultra-Violet (UV) light or Light Delivery Device (LDD). Dr. Grubbs won the Nobel Prize in Chemistry in 2005 for his theory of olefin metathesis, which is used in LAL technology.

How does the Light Adjustable Lens work?

The Light Adjustable Lens is made of a special photosensitive material that changes the shape and power of your implanted lens in response to ultraviolet (UV) light. Light treatments are delivered in your doctor’s office with the Light Delivery Device (LDD).

Why Choose a Light Adjustable Lens?

• Using a special lens material designed by a Nobel Prize-winning scientist, RxSight has developed the first intraocular lens (IOL) that allows you and your physician to optimize your vision following cataract surgery.

• Despite numerous advances in modern cataract surgery technologies, only 6 out of 10 cataract patients achieve their targeted vision, and an even smaller percentage achieve excellent vision at all distances. This is because it is very difficult to predict how your eye will heal before your cataract surgery.

• With the Light Adjustable Lens, you can now customize your vision after your cataract surgery. You will have the unique ability to adjust and preview your vision until it meets your personal desires and lifestyle requirements. This optimization is done by your eye doctor after lens implantation through a series of office-based light treatment procedures that take only a few minutes each.

• The Light Adjustable Lens delivers superior visual outcomes that non-adjustable IOLs cannot match. In a study of 600 subjects, those who received the Light Adjustable Lens followed by adjustments were twice as likely to achieve 20/20 distance vision at 6 months without glasses as those who received a standard monofocal IOL.

Precision Vision now offers LAL technology to improve post-cataract visual outcomes, especially in patients undergoing refractive lens exchange or cataract surgery that had previous refractive surgical procedures such as LASIK, PRK or RK. It’s also designed for patients seeking monovision (dominant eye corrected for distance and non-dominant eye corrected for near) or patients seeking more precise visual outcomes following their cataract or refractive lens exchange procedure.

The ideal candidates for Light Adjustable Lens implants are patients that are concerned about their best possible distance vision, a patient wanting monovision, or patients with a history of corneal surgery including LASIK, PRK, or RK for irregular corneas.
