2 results about "Eye surgery laser" patented technology

Laser eye surgery is in recent years more and more augmented and supported by the application of various photodisruptive laser pulse applications to the eye tissue. The here described inventions relates to several methods and system for improved laser eye surgery using photodisruptive laser pulses.

Method for controlling an ophthalmic surgical laser (18) for separating at least one volume body (12) with a predefined posterior interface (14) and a predefined anterior interface (16) from a human or animal cornea (32), comprising: - controlling the laser (18) by means of a control device (20) such that it emits pulsed laser pulses into the cornea (32) in a predefined pattern, wherein the control device (20) controls the laser beam (24) such that the volume body (12) is divided into at least two individual bodies (38, 40, 42) by means of photodisruption through an interaction of the individual laser pulses with the cornea (32), and the totality of the individual bodies (38, 40, 42) includes the posterior and anterior interfaces (14, 16) of the volume body (12), and wherein the laser (18) is controlled in this manner becomes,that at least one cut (36) or at least one opening is produced in the cornea (32) at a predefined angle and / or with a predefined geometry, wherein the cut (36) or the opening intersects an interface (14, 16) of the volume body (12) and extends to a surface (26) of the cornea (32) such that the individual bodies (38, 40, 42) of the volume body (12) can be removed from the cornea (32) via the cut (36) or the opening, and wherein the surface (26) of the cornea (32) is an artificially created surface of the eye by removing or moving an uppermost corneal layer and / or by producing a corneal flap.
