Characterization of a photochromic intraocular lens
Abstract:
We demonstrate an optical setup for characterization of a photochromic intraocular lens and present first measurement results of the kinetic properties and relative spectral transmittance of this photochromic lens. The lens showed a main absorption spectrum with a center wavelength of λ(c)=405 nm and a minimum relative transmission of 74% in the activated state. The coloring and bleaching times were within the manufacturer-provided specification of approximately 10 s for coloring and 30 s for bleaching.
