AFTER-TREATMENT OF REFRACTION CORRECTION BY OPHTHALMIC SURGERY

摘要

A planning system for generating control data, a treatment device for ophthalmic surgery to correct refraction, and a method for generating control data for such a treatment device, by which method it is easily possible to continue an interrupted treatment or correct a previous treatment. To this end, the planning system has calculating means for defining a corneal incision surface, wherein the calculating means determine the new corneal incision surface such that the existing corneal incision surface is incised by at least a part of the new corneal incision surface at an angle of between 60° and 120°.

主权项

1. A planning device for generating control data for a treatment apparatus for ophthalmic surgery, which cuts at least one incision surface in a cornea, using a laser device, wherein the planning device includes a calculation device for establishing a new cornea incision surface, wherein the calculation device establishes the new cornea incision surface based on data of a previously-introduced cornea incision surface and generates a control data set for controlling the laser device for the new cornea incision surface,
wherein the calculation device determines the new cornea incision surface in such a manner that the previously-introduced cornea incision surface is intersected by at least a part of the new cornea incision surface at an angle between 60° and 120°.
