The intraocular lens that enables patients to modify their eyesight following lens implantation is the LAL or light-adjustable lens. Many patients who have had cataract surgery gain a lot from LALs, enabling them to lessen or do without corrective eyewear.

LALs are made of a photosensitive substance that, following surgery, can be adapted to the eye to improve vision. By flashing a specific light onto the lens, the ophthalmologist can modify the patient’s vision. This changes the lens’s shape.

The fundamental benefit of LALs over conventional IOLs is the higher level of customization they provide.

Traditional intraocular lenses: What Are They and How Do They Work?

The most popular form of IOL or intraocular lens used in the US is a traditional IOL. They are constructed of PMMA, a transparent, flexible material. PMMA has long been a reliable material utilized in numerous medical goods, such as prosthetic joints and contact lenses.

The material used to construct conventional intraocular lenses is hard and cannot be modified after implantation.

Considering the patient’s age, eye condition, and other criteria, the eye doctor in this situation must select the best IOL for the patient before surgery.

IOLs have a price advantage over LALs, which is their principal benefit. The trade-off is that they offer less customizability and might not give the patient the greatest eyesight available.

Light-adjustable lenses versus conventional intraocular lenses

LALs

• Since LALs may be customized to the needs of each patient, they can treat nearsightedness, astigmatism, and farsightedness.
• LALs can be modified following surgery. Compared to IOLs, they may provide a larger field of vision.
• It has been demonstrated that LAL implants offer superior distance vision to conventional mono-focal implants.

IOLs

• Contrarily, conventional IOLs can only treat far- or near-sightedness.
• There are trade-offs when using IOLs; you can select a lens that offers you good distance vision but a weaker near image, or the opposite.
• IOLs are less suitable for distance vision than LALs because they exhibit higher degrees of halo and glare symptoms.

An ophthalmologist should select the best LAL implant
