Abstract

A method is provided for treating cataracts and other eye diseases, and includes the use of photopolymerizable compositions for preparing an intraocular-lens filling material which is used during an operation with an inserted intraocular-lens shell. The photopolymerizable compositions contain the following components: PA1 a) 90-99.99% by weight, preferably 94-99.799% by weight of at least one at least difunctional acrylic and/or methacrylic acid ester, PA1 b) 0.01-5% by weight, preferably 0.1-2% by weight, of at least one photoinitiator which is activatable with light in the wavelength range 400-500 nm, PA1 c) 0-9.98% by weight, preferably 0.001-2% by weight, of a UV-absorber which can absorb light of wavelengths <400 nm, and PA1 d) 0-9.98% by weight, preferably 0.1-2% by weight, of other auxiliary substances, such as dyes or activators for the photoinitiator, for example tertiary amines, the quantity particulars referring in each case to the total mass.
