Full video: How to select the BEST LENS IMPLANT for Premium Lens Replacement or Cataract surgery in 2023. [ Ссылка ]

The light adjustable lens or “LAL” enables patients to see far/mid and near with minimal halo effect at night when implanted into both eyes.

The LAL works well but involves more visits to our office than all of the other lens implants that we use.

If you choose the LAL, immediately after surgery and for the first 3 weeks after surgery, you will see well far away but will need to use reading glasses. Additionally during the first 2 months after surgery, you will be required to wear these UV blocking glasses during the daytime when outdoors. They don’t need to be worn indoors.

Starting 3 weeks after receiving the LAL, we use this Light delivery device to adjust and customize the focus of the LAL to improve the reading vision in one or both eyes.

So starting 3 weeks after receiving the LAL, in addition to seeing clearly far away without glasses you start seeing better close-up and at mid-range. We adjust the focus, have you test drive your vision in the real world for one week, then if another treatment or two is needed adjust how you see, we perform another LDD treatment to help you see your best at all distances far/mid and near. Once you like your vision, we then “lock-in” the setting of the LAL’s and your vision is then permanent and you can discontinue use of these UV blocking glasses 24 hours after your final lock-in treatment from the LDD.

Patients with the LAL generally will have one eye set to see better far and mid-range and the other eye slightly offset to see better mid-range and near. The target refraction is generally plano for the dominant eye and between -0.75 and -1.00 for the non-dominant eye. This difference between the eyes is significantly less than “monovision” where the eyes are different by between 1.5 and 2.0 diopters. The difference between the two eyes with the LAL is referred to as “blended vision” which is very well tolerated and performs better than monovision.

So, for patients that want full range of focus and minimal night halo, the LAL works great. For patients that have had success with monovision with contact lenses, the “blended vision” with the LAL works even better than monovision.

I have no financial interest in the light adjustable lens or RxSight. This is not a paid sponsorship.
