Abstract
A planning device for generating control data for a treatment apparatus which produces at least one cut surface in the cornea by operation of a laser device, and to a treatment apparatus including a planning device of the specified type. Also, a method for generating control data for such a treatment apparatus, and a method of eye surgery. In this case, a rotation of the cut surface about an axis running substantially parallel to the ocular axis is facilitated during the determination of the cut surfaces.
Claims18
A planning device for generating control data for a treatment apparatus for eye surgery, said treatment apparatus producing at least one cut surface in a cornea by application of a laser device, the planning device comprising:
- a calculation application that defines the at least one corneal cut surface based on an image of the cornea recorded before the cornea is brought into contact with a contact glass of the treatment apparatus;
- the calculation application defining the at least one corneal cut surface and generating a control data record that controls the laser device to make the at least one corneal cut surface;
- wherein the calculation application determines the at least one corneal cut surface to facilitate a rotation of the at least one corneal cut surface about an axis running substantially parallel to a selected ocular axis;
- and
- wherein a time between changing a setting of a rotation angle and establishing treatment readiness or an initiation of a treatment is less than three seconds.
A method of generating control data for a treatment apparatus for eye surgery which generates at least one corneal cut surface in the cornea by application of a laser device, the method comprising:
- providing corneal data;
- defining the at least one corneal cut surface;
- generating a control data record for the at least one corneal cut surface that controls the laser device based on an image of the cornea recorded before the cornea is brought into contact with a contact glass of the treatment apparatus;
- and
- determining the at least one corneal cut surface to facilitate a rotation of the at least one cut surface about an axis running substantially parallel to a selected ocular axis;
- and
- wherein a time between changing a setting of a rotation angle and establishing treatment readiness or an initiation of a treatment is less than three seconds.
A method for eye surgery, at least one corneal cut surface in the cornea being produced, comprising:
- providing corneal data;
- defining the at least one corneal cut surface on a basis of the corneal data based on an image of the cornea recorded before the cornea is brought into contact with a contact glass of the treatment apparatus;
- and
- generating a control data record for the at least one corneal cut surface;
- transferring the control data to the treatment apparatus;
- and
- producing the at least one corneal cut surface by controlling the laser device using the control data record;
- and
- determining the at least one corneal cut surface to facilitate a rotation of the at least one cut surface about an axis running substantially parallel to a selected ocular axis;
- and
- wherein a time between changing a setting of a rotation angle and establishing treatment readiness or an initiation of a treatment is less than three seconds.
