Frequently Asked Questions

The Light Adjustable Lens is made of a special photosensitive material that changes the shape and power of the implanted lens in response to ultraviolet (UV) light. The light treatments are delivered in-office by the RxSight® Light Delivery Device™ (LDD™). What makes the Light Adjustable Lens so unique is that these changes are made to the lens after experiencing your new vision once the lens has been implanted in your eyes and you have healed from surgery.

Please follow all instructions provided to you by your surgical eyecare team, including use of the RxSight UV-protective glasses that will be provided to you. As with any cataract surgery, your vision may not be perfect after surgery. While your surgical eyecare team selected the lens they anticipated would give you the best possible vision, it was only an estimate. Fortunately, you have chosen the Light Adjustable Lens! In the following weeks, you and your surgical eyecare team will work together to optimize your vision. Please make sure to pay close attention to your vision and be prepared to discuss preferences with your surgical eyecare team.

Showering
If there is a window or possible direct sunlight in your shower, please wear the RxSight UV-protective glasses in the shower or consider showering after the sun has gone down or before it comes up. If there is no direct sunlight, you do not need to wear your RxSight UV-protective glasses when you shower. However, please put them on immediately afterwards.

Sports
Your surgical eyecare team will advise you when you can return to sports. Your return to more impactful activities may need to be delayed until all light treatments are complete to guarantee a stable Light Adjustable Lens for light treatments.

Tanning Studio
A tanning studio bed is a very strong source of UV light and should be avoided until all light treatments are complete and you have been advised that you can remove your RxSight UV-protective glasses.

Makeup
Your surgical eyecare team will advise you when you can return to wearing eye makeup. Be careful when removing eye makeup and do not place excessive pressure on the eye. Permanent makeup should be delayed until the eye is considered fully healed by your surgical eyecare team.

Travel
Travel is permitted with the Light Adjustable Lens when approved by your surgical eyecare team. Please wear the RxSight UV-protective glasses as instructed.

Work
Work is not impacted, unless your profession puts you at a higher risk of UV exposure. Please remember to wear your RxSight UV-protective glasses at work until you are told by your surgical eyecare team that it is no longer necessary.

Laser Treatments
It is recommended that you wait until all light treatments are complete and you have been advised that you can remove your RxSight UV-protective glasses before proceeding with hair removal (IPL) treatments (different IPL devices use different wavelengths). This includes other facial beauty treatments that use light sources.

You will receive between 1 and 3 light treatments, each lasting approximately 90 seconds and separated by at least 3 days. The total number of light treatments is based on achievement of the desired visual outcome that you and your surgical eyecare team selected. Once you have achieved your final optimal vision, the lens power is permanently locked with 2 final light treatments to prevent any further changes.

Your vision may be blurry immediately after each treatment due to a gel used during application of the light treatment, but this should resolve quickly. Additionally, your eye will be dilated for the treatment, which may require wearing the tinted RxSight UV-protective glasses for a few hours. It may take approximately 24 hours after each light treatment to notice an improvement in your vision. The light from the LDD may also cause a temporary or long-lasting pink or red afterimage. This tinge to your vision is especially noticeable on things that normally look white, but should resolve before your next light treatment. Speak with your surgical eyecare team if the pink or red afterimage remains.

Important Safety Information

Approved use: The Light Adjustable Lens™ (LAL®), Light Adjustable Lens+™ (LAL+®), 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 LAL/LAL+ 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 LAL/LAL+. If you have any complications during your cataract surgery before the LAL/LAL+ is implanted, you may need to have another intraocular lens (IOL) implanted instead of the LAL/LAL+. What precautions should I be aware of? The safety and effectiveness of the LAL and LDD have not been established in patients with certain preexisting eye conditions or in patients who experience certain complications during cataract surgery. The safety and effectiveness of the LAL+ has not been substantiated in clinical trials. The effect of the LAL+ optical design on quality of vision, contrast sensitivity, and subjective visual disturbances have not been evaluated clinically. 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 LAL/LAL+ 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 risks 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. Click here for more patient information

LAL patients saw nearly as well without glasses (UCDVA) as control patients did with glasses (BCDVA).

The Light Adjustable Lens provides optimized vision for patient satisfaction.2

Light Adjustable Lens patients saw nearly as well without glasses (UCDVA) as control patients did with glasses (BCDVA).

Since the Light Adjustable Lens is a monofocal lens, there is low risk of dysphotopsias caused by splitting light, leading to potentially enhanced vision and patient satisfaction.

LAL patients are approximately two times more likely to achieve 20/20 vision or better without glasses at 6 months.

The Light Adjustable Lens offers LASIK-like accuracy in cataract surgery.2,3

92% of eyes (N = 391) achieved results within 0.50 D of target manifest refraction spherical equivalent (MRSE).

Patients are approximately two times more likely to achieve 20/20 vision or better without glasses at 6 months.

The study was a prospective, controlled, multicenter, 12-month study of 600 patients (ITT population) randomized to receive implantation with the RxSight LAL (N = 403) or a commercially available monofocal IOL (N = 197). Effectiveness analyses included 391 LAL patients and 193 control patients. Primary safety variables included best spectacle-corrected visual acuity (BSCVA) at 6 months and incidence of sight-threatening complications and adverse events. Primary effectiveness variables included percent reduction in manifest cylinder at 6 months, percent mean absolute reduction in MRSE at 6 months, and rotation of meridian of LAL at 6 months. Percent of eyes with an uncorrected visual acuity (UCVA) of 20/20 or better at six months post-operatively compared between the LAL treatment group and the monofocal control group was a secondary endpoint.

The Light Adjustable Lens corrects as low as 0.50 D of astigmatism, which is the lowest level approved to be treated.

The ability to treat 0.50 D of postoperative cylinder makes the Light Adjustable Lens the only IOL in the United States approved to correct this level of vision-altering astigmatism. Astigmatism of as little as 0.50 D can reduce visual acuity by one line, and the impact on dynamic, functional visual acuity and low-contrast acuity is even greater.1
