Cataract surgery is the most performed procedure in the United States. About 50% of Americans will develop cataracts by age 75 and, if left untreated, they can cause blindness.1
Cataracts form when the proteins and fibers in your eye’s natural lens begin to break down, causing hazy or cloudy vision. Once begun, cataracts only worsen until surgery is necessary.
Light enters the eye through the cornea, passes through the lens and is focused onto the retina, providing a crisp, clear image.
During surgery, a patient’s natural lens is removed and replaced with a clear synthetic one. The procedure usually takes approximately 15 minutes. If you have cataracts in both eyes, each eye is usually done on separate days. Typically, cataract surgery is performed while you are awake, though not until numbing eye drops have taken effect so that you don’t feel discomfort.
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.
The Light Delivery Device™ (LDD™) non-invasively delivers this UV light to precisely reshape your lens based on the visual correction that is needed to target your custom prescription.
RxSight offers two lenses in the Light Adjustable Lens platform: the Light Adjustable Lens and the Light Adjustable Lens+™. Your doctor will determine the lens that is best suited to your eyes. Both the LAL and LAL+ provide the same opportunity to customize your vision with your doctor after surgery.
UV light treatments will be performed in your doctor’s office after your eye has healed. Depending on your desired visual outcome, you may have 1–3 light treatments, followed by two “lock-in” treatments to prevent further changes.
With other lenses, you have to make a lot of decisions about the vision you want before your cataract surgery. Once implanted, those lenses can’t be changed; they’re what’s known as “fixed.”
The Light Adjustable Lens, however, is an adjustable lens. This means that the only decision you have to make before your surgery is to choose the Light Adjustable Lens. The rest can be made after your surgery once your eye has healed.
You and your surgeon then have the ability to adjust the lens and optimize your vision based on your unique preferences and lifestyle requirements. So you will truly have vision that’s just for you.
About three weeks after your cataract surgery, you’ll visit your doctor’s office to begin the light treatments to customize your vision. During these visits, you and your doctor work together to achieve the best possible visual outcome—the vision that’s best for you and your lifestyle.
Studies have shown that patients who received the Light Adjustable Lens and the recommended post-surgery treatments were almost twice as likely to achieve 20/20 vision or better without glasses compared to cataract patients who have standard lens implants.2

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.
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.
