Light Adjustable Lens

RxSight Light Adjustable Lens

Considering cataract surgery? If you are, it’s important to know about every option for IOLs (intraocular lenses) available. One option is the RxSight Light Adjustable Lens.

The Light Adjustable Lens is the first of its kind for patients with a moderate to a larger amount of astigmatism who don’t want to wear glasses after cataract surgery.

What Is The Light Adjustable Lens?

The Light Adjustable Lens is the only adjustable IOL available. By creating an adjustable lens, it allows for optimal optimization of vision after implanting the lens and healing.

The first step when choosing the Light Adjustable Lens is to have cataract surgery at Pepose Vision, where you’ll have your natural lens removed. After removing the natural lens and cataract, the adjustable IOL is then implanted where the natural lens once was.

After your eye heals from cataract surgery, you will return to your eye doctor. During this appointment, you’ll have your vision tested.

You’ll also be able to select a prescription for your adjustable lens. This prescription is based on your individual preferences, as well as what kind of lifestyle you lead.

Your ophthalmologist then applies a proprietary light treatment. This light treatment reshapes the implanted adjustable lens to the exact vision correction needs of your individual prescription. Most patients need anywhere between 2 to 4 total light treatments over a period of 1 to 2 weeks to reach their ideal vision goals.

How Does The Light Adjustable Lens Work?

Because the Light Adjustable Lens is made out of a special photosensitive material, it can change the power and shape of your implanted lens when exposed to UV light. When you have light treatments at your ophthalmologist’s office, they use a Light Delivery Device (LDD).

For patients with astigmatism, the Light Adjustable Lens can change lens shape, which is significant because it can reduce your astigmatism after cataract surgery. By reducing astigmatism, patients can experience improved vision without glasses. They may also reduce the chance that they will have large amounts of farsightedness, as well as nearsightedness.

If patients need to use glasses for close work like reading or working on a computer, the Light Adjustable Lens does not adjust its shape to reduce the need for these tasks.

What Are The Light Treatments For The Light Adjustable Lens Like?

Depending on healing time, light treatments will begin 17-24 days after your eye doctor implants the Light Adjustable Lens. How many treatments you’ll need varies, but it is usually one to three.

They last anywhere from 40 seconds to 2 and a half minutes. How long your treatments depend on the amount of correction that’s necessary after cataract surgery.

After each treatment, lock-in light treatment will be performed. This is to ensure that the correction is permanent.

Lock-in light treatment will last 90 seconds. Patients will need to wear special UV protective eyewear to protect the eye from UV light, as it could affect how the Light Adjustable Lens performs.

You’ll need to wear the protective eyewear from the time of your cataract surgery until the end of your light treatments.

Who Is A Good Candidate For The Light Adjustable Lens?

The only way to know for sure if you’re a good candidate for the Light Adjustable Lens is to schedule a cataract screening at Pepose Vision. But good candidates for the Light Adjustable Lens usually include the following:

  • Patients that have a cataract and need surgery to remove it
  • Patients that have a moderate to larger amounts of astigmatism (at least 0.75 diopters) before cataract surgery
  • Patients that do not have pre-existing macular disease
  • Patients with astigmatism and other refractive errors looking to reduce their dependence on glasses after cataract surgery
