The Light Adjustable Lens
The First And Only IOL Adjustable After Cataract Surgery
RxSight developed the first IOL that allows your physician to optimize your vision after your cataract surgery rather than trying to predict how the IOL will perform in your eye before your surgery.
With the Light Adjustable Lens, you will have the unique opportunity to adjust and preview your vision based on your personal desires and lifestyle requirements.
This optimization is done by your eye doctor after lens implantation through a series of light treatment procedures that take only a few minutes each.
Light Treatments
With your doctor’s input, the LDD non-invasively delivers 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.
Between 3 and 5 total light treatments, each lasting approximately 90 seconds, are required. The total number of light treatments is based on achievement of the desired visual outcome that you and your doctor selected. Once you have achieved your final optimal vision, the lens power is permanently locked with two final light treatments to prevent any further changes. When you experience the results of your adjustments, you will better understand the value of adjusting and customizing your vision after your surgery.
UV-Protective Glasses
You must wear UV-protective glasses from lens implantation until after the last light treatment is complete.
Until the LAL is locked in, exposing the lens to UV light sources (including the sun) could potentially modify the prescription.
Total wear is typically 4-6 weeks; however, this can vary depending on the number of light treatments needed.
Ask your doctor what activities you can participate in while completing light treatments. For example, you should not go to a tanning studio or receive facial beauty treatments (such as laser hair removal or permanent makeup).
Important Safety InformationApproved use: The Light Adjustable Lens and Light Delivery Device (LDD) system is approved for patients who have a cataract and need surgery for it, have corneal astigmatism (at least 0.75 diopters) before surgery and do not have preexisting macular disease.
Who should not receive this treatment? The Light Adjustable Lens and LDD system should not be used if you are taking medications that may increase your sensitivity to ultraviolet (UV) light; if you are taking a medication that is considered harmful to your retina; if you have a history of herpes eye infection or uncontrollable eye movements (nystagmus); or if you are unable to comply with your doctor’s schedule of LDD light treatments and instructions for wearing special UV-protective glasses for several weeks following cataract surgery.
What warnings should I be aware of? Preexisting macular disease and certain eye conditions may increase the risk of complications. Your doctor will determine if you are a good candidate for the Light Adjustable Lens. If you have any complications during your cataract surgery before the Light Adjustable Lens is implanted, you may need to have another intraocular lens (IOL) implanted instead of the Light Adjustable Lens.
What precautions should I be aware of? The safety and effectiveness of the Light Adjustable Lens and LDD have not been established in patients with certain preexisting eye conditions or ln patients who experience certain complications during cataract surgery You should discuss these issues with your doctor. Following surgery you must wear the special UV-protective glasses during all waking hours for about 4 to 5 weeks and comply with your doctor’s schedule of LDD light treatments. Failure to wear the UV-protective glasses can result in an unpredicted vision change or loss of vision quality after exposure to UV light, such as from sunlight. This may require a second surgery to remove the Light Adjustable Lens from your eye and replace it with another IOL.
What are the potential risks?
As with any surgical procedure, there are risks associated with cataract surgery and IOL implantation. Please discuss these risks with your doctor. Potential risk associated with LDD light treatments include mild alterations to color perceptions; temporary scratchiness, irritation, or dryness to the front part of your eye; and activation of a previously undiagnosed herpes eye infection. Longer lasting and serious adverse events related to the UV light exposure are possible, but rare. There is a small chance that your vision could be made worse or that you may require additional surgery as a result of a complication.
Caution: Federal law restricts this device to sale by or on the order of a physician.
The Light Adjustable Lens delivers superior vision outcomes that non-adjustable lOLs 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 vision at 6 months without glasses as those who received a standard (fixed) monofocal IOL.
