The IOL has UV light filtering material concentrated along the posterior aspect of the optic which protects the retina during overexposure to UV radiation during adjustments and lock-in treatments. Particles or monomers can easily migrate within the lens and do so when exposed to ultraviolet light. He added that to flatten the center of the lens to treat myopia, you would expose the light to the periphery of the lens and the monomers would migrate there, and subsequently thicken the periphery of the implant and flatten the center. Brierley L. Refractive results after implantation of a light-adjustable intraocular lens in postrefractive surgery cataract patients.
