Ultraviolet-Absorbing Intraocular Lens Implants

  • David Miller


As our prostheses improve they tend to mimic the natural product more and more. However, in copying the human lens, we must decide upon which age of the human lens we would like to mimic because with age the human lens changes its properties. For example, the lens of a child accommodates 15 diopters, probably transmits some ultraviolet (UV) light,* is crystal clear, and is thinner, smaller, and lighter in weight than that of the adult. As we age, the lens thickens, loses accommodative flexibility, yellows, fluoresces, and absorbs more UV light.1,2 Presently, the choice is somewhat simplified for manufacturers because they have no way of giving an intraocular lens (IOL) accommodation. The key variables that they can influence are power, shape, and UV transmission.
