Determination of the action spectrum of the blue-light hazard for different intraocular lenses.
The spectral transmittance of various models of intraocular lenses (IOLs) has been studied. Significant differences among them were found, primarily regarding the cutoff wavelength. Based on these findings, modifications of the action spectrum for the blue-light hazard photobiological effect are proposed for each type of IOL. Moreover, the potential hazard of a representative range of radiation sources to subjects implanted with those IOLs has been calculated based on the corrected action spectra.
