    Abstract:
    PURPOSE: To determine the optical transmission properties of a recently introduced intraocular lens (IOL) (AcrySof Natural SN60AT, Alcon Laboratories) and compare them with those of a conventional IOL (AcrySof SA60AT, Alcon Laboratories) after ultraviolet (UV)-visible light irradiation. SETTING: Eye Clinic and Department of Clinical Physiopathology, University of Florence, and the National Institute of Applied Optics, Florence, Italy. METHODS: Two IOLs, the AcrySof Natural with a UV and blue-light filter and the AcrySof without a blue-light filter, were studied. Three IOLs of each model with different dioptric powers were examined in two experimental setups. The samples were stressed with very high irradiance to reproduce light aging, and the transmission properties of the IOLs were studied. RESULTS: No significant decrease in transmission was found at a UV-visible light dose equivalent to 100 years of light aging. CONCLUSION: The AcrySof Natural IOL has stable optical characteristics.
