Light Adjustable Lens From RxSight®
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.
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.1

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 to optimize your vision. These light treatments are delivered in your doctor’s office with the Light Delivery Device (LDD) after your eye has healed.
If you select the Light Adjustable Lens, the first step is to have your cataract safely removed and the adjustable IOL implanted. The cataract removal and IOL implantation procedure is the same as if you selected a non-adjustable IOL.
After Cataract Surgery
After your Light Adjustable Lens has been implanted in your eye, it is adjusted to deliver the customized vision you desire. This means that there are 2 major differences following your surgery as compared to a non-adjustable IOL:
UV Protective Glasses
Exposure to indoor and outdoor sources of UV light can cause uncontrolled changes to the Light Adjustable Lens. To prevent this, you will be provided with UV protective glasses to wear immediately following surgery during all waking hours (from time of lens implantation until after the last light treatment is completed).
Your protective glasses may be removed when sleeping, and may be temporarily removed when showering, washing your face, or applying eye drops as long as you are not exposed to direct sunlight.
Twenty-four hours after your final light treatment, no further changes can be made to the implanted Light Adjustable Lens, and you can remove the UV protective glasses and enjoy your custom vision!
How Are the Light Treatments Performed?
Once your eye has healed, you will return to your eye doctor to have your vision tested. During this visit you will be able to preview and compare possible vision outcomes based on your unique preferences and lifestyle requirements before selecting a prescription for your adjustable lens.
To receive the light treatment, you will be placed in front of the Light Delivery Device (LDD). The LDD non-invasively delivers the UV light to precisely reshape your Light Adjustable Lens based on the visual correction that is needed to target your custom prescription.
Light Treatment Schedule
A minimum of 2 light treatments—each lasting approximately 90 seconds and separated by approximately 3 days—are required. The total number of light treatments is based on achievement of the desired vision outcome that you and your doctor selected.
Once you have achieved your final optimal vision, the lens power is permanently locked in with a final light treatment to prevent any further changes.
Who Can Benefit?
The U.S. Food and Drug Administration has approved the Light Adjustable Lens and Light Delivery Device for patients with pre-existing astigmatism of 0.75 diopters or more who are undergoing cataract surgery.
Other commercially available IOLs may be available for the treatment of your cataracts and your doctor will help you determine which lens is right for you.
