Abstract

An ophthalmological laser therapy device including a laser system, an x-y scanner, collecting optics and a z-scanner. The invention also relates to a method for processing a tissue of an eye by a therapeutic laser beam of an ophthalmological laser therapy device. The invention provides an ophthalmological laser therapy device and a corresponding method which permit, with minimal engineering complexity, a very quick positioning of the laser spot in a large volume region, in particular in a large x-y region perpendicular to the optical axis. The problem is also solved by a method for processing a tissue of the eye or a material located in an eye using an ophthalmological laser therapy device, wherein each sub-section of the tissue of the eye is processed using a corresponding positioning or the device for the adjustable redirecting of the laser beam in an image field of the collection optics.
