Embodiment Construction

[0023] figure 1 A schematic diagram of a treatment device 10 is shown with an ophthalmic surgical laser 18 that separates a predetermined corneal volume or volume 12 from predetermined interfaces 14, 16 of the cornea of ​​a human or animal eye by photodisruption. It is recognized that, in addition to the laser 18, the control device 20 for the laser 18 is formed such that it emits pulsed laser pulses into the cornea in a predetermined pattern, wherein the interfaces 14, 16 of the volume 12 to be separated pass through Photodisruption occurs in a predefined pattern. In the illustrated embodiment, the interfaces 14, 16 form a lenticular volume 12, wherein the position of the volume 12 is selected such that a pathological and / or unnaturally altered region 32 within the corneal stroma 36 is enclosed (see figure 2). Additionally, from figure 1 It can be seen that a so-called Bowman's membrane 38 is formed between the stroma 36 and the epithelium 28 .

Abstract

The present invention relates to a method for controlling an ophthalmic surgical laser for the separation of a volume body (12) with predefined interfaces (14, 16) from a human or animal cornea, comprising controlling the laser (18) by means of a control device (20) such that it emits pulsed laser pulses in a predefined pattern into the cornea, wherein the interfaces (14, 16) of the volume body (12) to be separated are defined by the predefined pattern and the interfaces (14, 16) are generated by means of photodisruption, wherein the interfaces (14, 16) of the volume body (12) are determined such that a pathological and / or unnaturally altered area (32) within the stroma of the cornea is enclosed. Furthermore, the invention relates to a treatment device (10) with at least one ophthalmic surgical laser for the separation of a predefined corneal volume (12) with predefined interfaces of a human or animal eye by means of photodisruption and at least one control device (20) for the laser orlasers (18), which is formed to execute the steps of the method according to the invention.

Description

technical field [0001] The invention relates to a method for controlling an ophthalmic surgery laser for separating a volume with a predetermined interface from a human or animal cornea. Furthermore, the invention relates to a treatment device having at least one ophthalmic surgical laser for separating a predetermined corneal volume from a predetermined interface of a human or animal eye by photodisruption, and at least one laser for the one or more lasers control means, as well as computer programs and computer readable media. Background technique [0002] Opacities and scarring in the cornea can result from inflammation, injury, or natural disease that impairs vision. Especially in the case of these pathologically and / or unnaturally altered areas of the cornea located in the visual axis of the eye, apparent vision is greatly disturbed. In a known manner, by means of so-called phototherapeutic keratectomy (PTK), the regions altered in this way are eliminated by means of ...
