Definitions

  • Transparent objects present a unique challenge for orientation with regard to inversion, rotation and translation of the object, because it is impossible to, by only visual inspection, conclude whether a marker is positioned on the front side or back side of the transparent object.
  • the present document discloses marking systems with chiral arrangements of markers to provide the desired, unambiguous, orientation or positioning of transparent objects with regard to inversion, rotation and translation of the object relative to a reference position. Unambiguous positioning is especially important for objects with rotational asymmetry and objects with inversional asymmetry and objects with a combination of rotational asymmetry and inversional asymmetry. In the latter case, for example, the anterior and posterior surfaces of a transparent object have different functions and should be positioned accordingly.
  • Objects can have supporting components, which can be rotationally and/or inversionally asymmetric.
  • intraocular lenses comprise haptics, to, for example, anchor the optical elements in the eye. Most such lenses must be implanted in the eye in the intended position with regard to rotation, inversion and translation to functioning properly.
  • Markers include dedicated markers and marking features.
  • a dedicated marker is a feature which has no other function except for said marking, for example an engraved dot on the rim of the object.
  • Marking features are existing features of the object which also provide for a marker, meaning an existing feature of the object which also provides a marking function in addition to at least other function.
  • a connection point of a haptic can double as a marking feature, see Figure 3.
  • a marking system with chiral arrangement can comprises at least one dedicated marker, meaning a feature of the object which provides a marking function only, or, alternatively, can comprises at least one marker feature, meaning an existing feature of the object which also provides a marking function in addition to at least other function, or, alternatively, can comprise any combination of any number of dedicated makers and marker features.
  • the invention also relates to a marking system with chiral arrangement wherein the system comprises a combination of at least two singular markers which combination is adapted to provide said chiral function. It is however also possible that the system comprises at least one complex marker adapted to provide said chiral function.

Abstract

L'invention concerne un système de marquage destiné à des objets transparents qui comporte au moins une configuration de marqueurs, la configuration comportant au moins un marqueur et étant une configuration chirale conçue pour remplir une fonction chirale. La fonction chirale signifie que la configuration chirale est adaptée pour assurer une orientation par rapport à l'inversion, à la rotation et à la translation d'objets transparents inversement asymétriques. L'invention concerne aussi un objet transparent comportant au moins un marqueur de manière à obtenir une orientation par rapport à l'inversion, à la rotation et à la translation des objets par rapport à une position de référence, le marqueur présentant une structure chirale adaptée pour remplir une fonction chirale. Selon l'invention, il est important de positionner de manière non ambiguë les objets présentant une asymétrie de rotation ou une asymétrie d'inversion et les objets présentant une combinaison d'asymétrie de rotation et d'asymétrie d'inversion. Dans ce dernier cas, les surfaces antérieure et postérieure d'un objet transparent remplissent des fonctions différentes et doivent être positionnées en conséquence.
