Photoprotection and photoreception of intraocular lenses under xenon and white LED illumination.

Objective. To analyze the photoprotection and phototransmission that various intraocular lenses (10Ls) provide under the illumination of a xenon (Xe) lamp and white LEDs (light emitting diode). Methods. The spectral transmission curves of six representative 10Ls were measured using a Perkin-Elmer Lambda 35 UV/VIS spectrometer. Various filtering simulations were performed using a Xe lamp and white LEDs. The spectral emissions of these lamps were measured with an ILT-950 spectroradiometer. Results. The 10Ls analyzed primarily show transmission of nearly 100% in the visible spectrum. In the ultraviolet (UV) region, the filters incorporated in the various 10Ls did not filter equally, and some o…
