Abstract:
1. Apparatus for generating an alteration of biomechanical properties of a cornea ( 10 ) that contains photosensitizer ( 14 ), further comprising means for radiating into the cornea ( 10 ) electromagnetic radiation ( 12 ′) which with the photosensitizer ( 14 ) brings about a cross-linking, wherein the means ( 18 , 20 ) for radiating set a depth of action ( 16 , 16 ′) of the electromagnetic radiation ( 12 ′) in the cornea ( 10 ) in such a manner that, starting from the anterior surface ( 10 a ) of the cornea ( 10 ), in the direction of the radiation as far as a predetermined depth of action ( 16 , 16 ′) an outer part of the cornea is exposed to electromagnetic radiation which is partially absorbed as far as the predetermined depth of action, whereas in deeper regions of the cornea close to the back ( 10 b ) thereof the electromagnetic radiation has no effect, wherein the depth of action is the depth of penetration of the electromagnetic radiation into the cornea.
