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.
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.
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.
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.
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
While your vision is still in the adjustment phase, you will be required to wear glasses that prevent UV light from altering your lens to protect it before the final lock-in.

The LAL provides optimized vision for patient satisfaction.2
LAL patients saw nearly as well without glasses (UCDVA) as control patients did with glasses (BCDVA).
Since the LAL is a monofocal lens, there is low risk of dysphotopsias caused by splitting light, leading to potentially enhanced vision and patient satisfaction.
The LAL 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 LAL corrects down to 0.5 diopters of astigmatism, which is the lowest level approved to be treated.
