A treatment device for operative vision correction of an eye, a method for generating control data therefor and methods for surgical correction of defective vision of an eye

摘要

A treatment device for surgical correction of hyperopia on the eye (3) is described, wherein the treatment device (1) has a control device (12) controlled laser device (L), which by irradiation of laser radiation (2) separates corneal tissue, wherein the control device ( 12) is adapted to control the laser device (L) for emitting the laser radiation (2) into the cornea (5) in such a way that a lenticular volume (18) is isolated in the cornea (5) whose removal from the cornea (18 ) causes the desired hyperopia correction, wherein the control device (12) in the activation of the laser device (L) of the lenticular volume (18) so pretends that it has a posterior surface (20) and an anterior surface (19) whose edges over a Boundary surface (24) are connected, wherein the edge has a width (B) which is greater than that which would have a straight line in the same projection, which at the edge of the posterior o of the anterior surface (20, 19) is perpendicular to the respective surface and connects the anterior surface (19) with the posterior surface (20) or with their imaginary continuation.
