Abstract
The invention relates to an ophthalmologic implant, in particular an intraocular lens. The implant includes at least one marker produced with at least one dye which is a fluorescent dye having a maximum emission outside of the light spectrum visible to humans or an absorbing dye having a maximum absorption outside the light spectrum visible to humans. The said fluorescent or absorbing dye does not substantially influence light transmission of the ophthalmologic implant within the visual spectral range. The invention further relates to a microscopy system and an optical detection process for detecting and/or identifying the disclosed ophthalmologic implant.
Claims17
An ophthalmologic implant including at least one mark comprising a fluorescent dye with an emission maximum outside of the light spectrum visible to a human,
- wherein the fluorescent dye does not substantially influence light transmission of the implant in the visual spectral range and is from at least one structural class selected from the group consisting of cyanines, merocyanines, phthalocyanines, rhodamines, porphyrines, chlorophylls, triarylmethanes, xanthenes, oxazines, thiazines, safranines, heterocyclic pyrylium and thiapyrylium salts, perrylenes, terrylenes, quaterrylenes, quaterneles, azo dyes, metal complexes, and chinones, and
- the at least one mark designating posture or position of the implant when illuminated with white light or with light of a spectral range that effects corresponding fluorescence of the dye outside of the light spectrum visible to the human.
An ophthalmologic implant including at least one mark composed of one or more dyes a fluorescent dye with an emission maximum outside of the light spectrum visible to a human,
- wherein the fluorescent dye does not substantially influence light transmission of the implant in the visual spectral range and is from at least one structural class selected from the group consisting of cyanines, merocyanines, phthalocyanines, rhodamines, porphyrines, chlorophylls, triarylmethanes, xanthenes, oxazines, thiazines, safranines, heterocyclic pyrylium and thiapyrylium salts, perrylenes, terrylenes, quaterrylenes, quaterneles, azo dyes, metal complexes, and chinones, and
- the at least one mark designating posture or position of the implant when illuminated with white light or with light of a spectral range that effects corresponding fluorescence of the dye outside of the light spectrum visible to the human.
