Description

Die Erfindung betrifft eine Weitereintwicklung der im Patent Nr. 42 27 514 beschriebenen Erfindung. Diese Erfindung betrifft Sehhilfen bei Erkrankungen der Netzhaut, insbesondere bei Netzhautablösung mit Beteiligung der Macu­ la.The invention relates to a further development of the Patent No. 42 27 514 invention described. This Invention relates to visual aids for diseases of the retina, especially with retinal detachment with the involvement of the Macu la.

Gemäß Hauptpatent werden Sehhilfen vorgeschlagen, die gekennzeichnet sind durch eine Kreuzlinienrasterung und die die äußere Form einer Brille aufweisen können.According to the main patent, visual aids are proposed that are characterized by a cross line grid and the can have the outer shape of glasses.

Nunmehr wurde festgestellt, daß die mit einer Kreuzlinien­ rasterung versehene Linse auch in Form einer Kontaktlinse oder als implantierbare prothetische Linse angewendet wer­ den kann.It has now been found that the cross lines Screened lens also in the form of a contact lens or used as an implantable prosthetic lens that can.

Anstelle einer Kreuzlinienrasterung können die Lin­ sen auch eine Vielzahl von konzentrischen Kreisen ent­ sprechend Zusatzanmeldung P 42 33 383.0 aufweisen, da sich damit die gleiche Wirkung erzielen läßt.Instead of a cross line grid, the Lin also create a variety of concentric circles accordingly have additional application P 42 33 383.0 because so that the same effect can be achieved.

Die erfindungsgemäßen weichen oder harten Kontaktlinsen oder implantierbaren Linsen können aus anorganischem Glas oder vorzugsweise aus physiologisch unbedenklichen Kunststoffen bestehen. Kontaktlinsen aus Kunststoffen sind an sich bekannt und werden seit Jahrzehnten verwendet, so daß es dem Fachmann keine Schwierigkeiten bereitet, geeignete Kunststofflinsen für den jeweiligen Patienten aus dem vorhandenen Angebot aus­ zuwählen. Die Kreuzlinienrasterung oder die Einarbeitung kon­ zentrischer Ringe kann ebenfalls in an sich bekannter Weise durch Gravieren, Schneider oder Fräsen, insbesondere mit Hilfe von Laserstrahlen, durchgeführt werden. Falls der Patient zusätzlich Sehkorrekturen benötigt, können die Linsen weiter­ hin auch entsprechend und in bekannter Weise geschlif­ fen werden.The soft or hard contact lenses according to the invention or implantable lenses can be made of inorganic glass or preferably from physiologically harmless plastics consist. Plastic contact lenses are known per se and have been used for decades, so that the skilled person no problems, suitable plastic lenses for the respective patient from the available offer to choose. The cross line grid or the incorporation con centric rings can also in a conventional manner by engraving, tailoring or milling, especially with the help of laser beams. If the patient If additional vision correction is required, the lenses can continue also ground accordingly and in a known manner be opened.
