Light Adjustable Lens (LAL)


Light Adjustable Lens (LAL)

Optimize your vision after cataract surgery with the most advanced intraocular lens, designed using technology that earned the 2005 Nobel Prize in Chemistry.

An Overview: Light Adjustable Lens (LAL)

Achieve your desired vision after cataract surgery with the Light Adjustable Lens. The latest and most advanced intraocular lens (IOL) — or, lens implant.

The LAL can correct near, intermediate, and distance vision, as well as astigmatism. It offers near vision correction using Extended Depth Focus (EDF) technology, which allows us to improve your near and immediate vision without impacting your distance vision. Made of special photosensitive silicone material, the LAL is a glare-free, halo-free, shine-free solution.

The Light Adjustable Lens improves upon existing IOL technology: Lens implants have come a long way, with newer designs offering multifocal or accommodating lenses; however, unpredictable outcomes sometimes require additional vision correction procedures. The LAL — specifically its unique adjustable properties — was developed to give you absolute flexibility, post-cataract surgery, to ensure your vision is just right. Moreover, the LAL is ideal for patients who have had refractive surgery.

Light Adjustable Lens: Benefits and Highlights

  • 2x as likely to achieve 20/20 distance vision at six months than with standard IOL.
  • Highly customizable alternative to other IOLs.
  • No halos, no glare.
  • Noninvasive, painless adjustments.
  • Improve near vision without decreasing distance vision.

What to Expect: About the Procedure

  • Lens implant surgery first
  • Healing period, about two weeks
  • Vision exam to determine power of lens
  • 2-4 light treatments at 90 seconds each
  • About three days between treatments

Your Light Adjustable Lens (LAL) experience begins with conventional cataract surgery or IOL implant surgery. After a healing period of about two weeks, you’ll return to CODET for a routine eye exam. We’ll determine your prescription and then begin the process of adjusting the lenses to fit your vision and lifestyle needs. This usually takes between two to four 90-second, painless light delivery treatments, with three days between each visit.

The cataract on Robert’s left eye was getting cloudy, and it became a challenge to see out of it. His dentist friend recommended CODET, and he and his wife made the appointment and then the trip.

I had the surgery yesterday, and today I’m seeing so much better. The doctors and staff have been absolutely wonderful. I would highly recommend CODET to anyone who needs eye surgery or any kind of eye care period
