摘要:
To obtain polymeric lens materials that absorb both UV and short wavelengthvisible light, it is common to add separate UV-absorbing and short wavelengthlight-absorbingchromophores to the polymeric materials. However, having a single chromophorethat absorbsboth can reduce the number of components added to the lens material and reducedisruption tothe primary polymer chain structure of the lens. The present invention relatestochromophores that absorb both UV and short wavelength visible light. Thechromophores areparticularly suitable for use in intraocular lens materials. The chromophoresof the presentinvention relate to the formula:(see above formula)wherein A=H or CH3; X=O or NH; n=2-6; m=0-6; and R=H, C1-C4 alkyl, or C1-C4alkoxy.
