Description

Die Erfindung betrifft eine Kontaktlinse zum Erzeugen von Schnitten in der Hornhaut des Auges.The invention relates to a contact lens for producing Incisions in the cornea of the eye.

Viele Erkrankungen des Auges beruhen auf Veränderungen des brechenden Systems des Auges, z.B. gehören hierzu der Astigmatismus und der Keratokonus. Andere Erkran­ kungen lassen sich durch Anpassung des brechenden Systemes an anatomische Fehlformen lindern. Hierzu gehören bspw. die Hyperopie und die Myopie.Many eye diseases are based on changes the refractive system of the eye, e.g. belong to this astigmatism and keratoconus. Other crane can be adjusted by adjusting the refractive index Relieve systemic anatomical malformations. For this include, for example, hyperopia and myopia.

Bei diesen Erkrankungen oder Anomalien ist eine chirur­ gische Behandlung bekannt, und zwar u.a. durch Veränderung der Brechkraft der Hornhaut. Dabei werden mit dem Skalpell Schnitte in entsprechender Anordnung in die Hornhaut eingebracht, um deren Brechkraft zu verändern.With these diseases or anomalies is a surgeon known treatment, i.a. by Change in the refractive power of the cornea. In doing so with the scalpel cuts in an appropriate arrangement introduced into the cornea to increase its refractive power change.

Unabhängig davon ist es auch bekannt, bei der Behandlung von Augenerkrankungen Laserlicht zu verwen­ den, und entsprechende Versuche sind auch schon unter­ nommen worden, um mittels dieses Laserlichtes den mit einem Skalpell ausgeführten Schnitten entsprechende Schnitte in die Hornhaut einzubringen. Nachteilig bei diesen Versuchen war aber, daß diese Schnitte nicht re­ produzierbar und genau in die Hornhaut eingebracht werden konnten.Regardless, it is also known at the Treatment of eye diseases using laser light the, and corresponding attempts are already under been taken to use the laser light with cuts made according to a scalpel Make cuts in the cornea. A disadvantage of These attempts were, however, that these cuts were not right producible and precisely inserted into the cornea could become.

Der Erfindung liegt daher die Aufgabe zugrunde, eine Kontaktlinse vorzuschlagen, mit dem reproduzierbar und genau Schnitte in der Hornhaut des Auges erzeugt werden können. The invention is therefore based on the object Propose contact lens with the reproducible and exactly cuts are made in the cornea of the eye can.  

Gelöst wird diese Aufgabe mit den Merkmalen gemäß dem Anspruch 1.This task is solved with the characteristics according to claim 1.

In bevorzugter Ausgestaltung wird eine Kontaktlinse vorgeschlagen, wie sie in den Ansprüchen 2-4 angegeben ist.In a preferred embodiment, a contact lens proposed as set out in claims 2-4 is specified.

Die Erfindung sowie die Vorteile, die sich aus der erfindungsgemäßen Lösung ergeben, sollen nachfolgend unter Bezug auf die Zeichnungen erläutert werden, wobei diese in vereinfachter Darstellung unterschiedliche Muster in einer Kontaktlinse zeigen.The invention and the advantages resulting from the solution according to the invention should follow will be explained with reference to the drawings, wherein these in a simplified representation different Show patterns in a contact lens.

Erfindungsgemäß wird zunächst auf die Hornhaut eine Kontaktlinse aufgelegt, - und zwar kann es sich dabei um eine harte oder weiche Kontaktlinse handeln, - die nur aus einem Cornealteil bestehen kann, aber die auch ein Skleralteil aufweisen kann. Diese Kontaktlinse kann bspw. mit einem Material beschichtet sein, das das Laserlicht reflektiert. Als Beispiele wären zu nennen eine Aluminiumbeschichtung oder aber auch eine dielektrische Beschichtung. Die Linse 1 ist, wie die Fig. 1 und 2 andeuten sollen, mit Mustern versehen, wobei es sich hierbei um entspre­ chend dicht angeordnete Perforierungen oder aber um spaltförmige Ausnehmungen 2 handeln kann. Zweckmäßig ist es, wenn im zentralen Bereich der Linse eine Fixa­ tionslücke 3 vorhanden ist, durch die der Patient hindurchsehen kann, um auf diese Weise das Auge ruhig zu halten. Es sei in diesem Zusammenhang bemerkt, daß auch geringe Unruhen nicht stören, da das ganze Auge an sich homogen beleuchtet wird.According to the invention, a contact lens is first placed on the cornea, and this can be a hard or soft contact lens, which can only consist of a corneal part, but which can also have a scleral part. This contact lens can, for example, be coated with a material that reflects the laser light. Examples include an aluminum coating or a dielectric coating. The lens 1 is, as the FIGS. 1 and 2 are intended to indicate, provided with patterns, which may be perforations accordingly arranged densely or else gap-shaped recesses 2 . It is useful if there is a fixation gap 3 in the central region of the lens through which the patient can see through, in order to keep the eye still in this way. It should be noted in this connection that even minor riots do not interfere, since the entire eye itself is illuminated homogeneously.

Nach dem Auflegen der mit diesen Perforierungen oder Schnitten versehenen Linse auf die Hornhaut, kann mittels eines geeigneten Laserlichtes, das auf der Linse befindliche Muster reproduzierbar und äußerst genau in die Hornhaut eingeschnitten werden. Eine über­ mäßige Erwärmung der Linse ist bei entsprechender Wahl des Linsenmaterials bzw. der Beschichtung der Linse nicht zu erwarten.After hanging up with these perforations or Cut lens on the cornea, can by means of a suitable laser light, which on the  Lenticular patterns are reproducible and extreme cut exactly into the cornea. An over moderate heating of the lens is appropriate choice of the lens material or the coating of the lens not to be expected.

Claims (4)

1. Kontaktlinse zum Abschirmen bestimmter Bereiche der Hornhaut des Auges beim Schneiden dieser mittels Laserstrahl, wobei auf die Hornhaut eine diese teilweise abdeckende Kontaktlinse aufgelegt wird und anschließend die nicht abgedeckten Bereiche der Hornhaut dem Laserlicht ausgesetzt werden, dadurch gekennzeichnet, daß die Kontaktlinse entsprechend den zu erzeugenden Schnitten ausgebildete, Laserlicht hindurchlassende Bereiche aufweist.1. Contact lens for shielding certain areas of the cornea of the eye when cutting them by means of a laser beam, a partially covering contact lens being placed on the cornea and then the uncovered areas of the cornea being exposed to the laser light, characterized in that the contact lens corresponds to the generating sections formed, laser light transmitting areas. 2.
