Abstract
By measurement of spectral sensitivity functions it was shown that the irradiation of the retina with short visible wavelengths increases by a factor of 20 after implantation of intraocular lenses. According to recent investigations, the possibility of photochemical retinal damage and the development of macular degeneration is thereby increased considerably. It is discussed to what extent the Irvine-Gass-Norton syndrome observed in a particular patient two years after operation is associated with increased retinal irradiation. A protective glass filter is described which brings the spectral sensitivity function of pseudophakic patients down into the physiological range without changing color vision and brightness sensation; moreover, it provides a high degree of protection against phototoxic UV radiation, to which (according to Williams et al.; 1983) pseudophakic patients are 300 times more exposed.Keywords
