RXSight Light Adjustable Lens
Achieving Customized Vision With the Light Adjustable Lens™
The Light Adjustable Lens is the only adjustable intraocular lens (IOL) available that allows optimization of your vision after lens implantation and healing. If you and Dr. Griffin 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.
What is unique about the Light Adjustable Lens is that once your eye has healed, you 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. Your doctor will then apply a proprietary light treatment that precisely reshapes your implanted lens based on the visual correction that is needed to target your custom prescription. You may need 3 to 5 total light treatments to reach your vision goals.
Your vision is tested after your eye heals. You then sample and select your desired vision outcome.
How Does It 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).
Is the Light Adjustable Lens right for me?
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.
What to Expect Following Your 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 intraocular lens (IOL):
- Required wear of ultraviolet (UV) protective glasses
- Completion of light treatments
Why do I need to wear 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?
To receive the light treatment, you will be placed in front of the office-based Light Delivery Device (LDD). The LDD non-invasively delivers the UV light to your Light Adjustable Lens to adjust your vision to the desired target. The system gives your doctor the flexibility to make adjustments and refinements to meet your specific criteria. Following the light treatment, you will be rechecked in approximately 3 days to assess your vision.
Light treatments are delivered in your doctor’s office with the Light Delivery Device.
Between 3 and 5 total 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. When you experience the results of your adjustments, you will better understand the value of adjusting and customizing your vision after your surgery.
Once you have achieved your optimal vision, the lens power is permanently locked in with a final light treatment to prevent any further changes.
