Objective: To compare colour vision in patients implanted with yellow and clear intraocular lenses (IOLs) using a new method allowing evaluation of the whole visible spectrum, with results provided according to the different wavelengths.
Methods: Ten eyes of 5 patients were enrolled in a blue-light filtering fellow-eye control study. The patients were implanted with a yellow IOL in one eye and a clear IOL in the fellow eye after cataract surgery. Twelve months postoperatively, monocular FMHUE-Test was performed under photopic and mesopic light conditions. The data was analyzed with a new program that provides results according to the different wavelengths, besides the total error score.
Results: The mean FMHUE total error score in the yellow lenses was 98.6 and in the clear lenses 85.3. The wavelength oriented evaluation showed an enhanced error of the yellow lenses in wavelength from 470nm to 620nm.
Conclusions: In this preliminary study we demonstrate that this new method for evaluation of colour vision offers more detailed information on potential differences between IOLs with different colour filters.
