Abstract
The invention provides an irradiating device and a program which can appropriately set a cross sectional shape of human tissue at a time of incising the human tissue by beam irradiation. For example, when a cornea (100) is incised by an irradiating device which outputs femtosecond laser, a cross sectional shape in an intersecting direction to a direction of advancing to a back surface side from a front surface side of the cornea in an incision (101) is set to a non-rectilinear shape, for example, a circular arc shape. As a result, there can be achieved effects such as suppression of drawing of the incision in the case of inserting the instrument by opening the incision, and self-closing of the incised site.
Claims4
An irradiating device comprising:
- an output means which outputs operation beam having a function of making an incision on a cornea of an eye;
- a control means which controls at least an irradiating direction of said operation beam in such a manner as to form an incised site for inserting an intraocular lens into an interior of the eye, the incised site penetrating from an outer front surface of the cornea of the eye to an inner front surface, by the operation beam output from the output means;
- and
- a setting means which sets a cross sectional shape in a direction intersecting an advancing direction from an opening of the outer front surface of the cornea in said incised site toward an opening of the inner front surface, to the other linear shape than a rectilinear shape in which a convex shape collapsing onto the inner front surface from the outer front surface of the cornea is formed at least in one of both sides of said incised site, in the case of inserting the intraocular lens through said incised site, and accepts an input from a user,
- wherein said setting means comprises:
- a display means which displays an image of an operation part;
- and
- a superposition setting means which superposes the image of the operation part displayed by the display means, and accepts an input setting a shape of an advancing route heading for the inner front surface from the outer front surface of the cornea of the eye in the incised site, and a cross sectional shape in a direction intersecting said advancing route in the incised site, and
- wherein said superposition setting means can accept a cross sectional shape in which said cross sectional shape changes in correspondence to the position on said advancing route in the incised site.
A program making a computer as the following means comprising:
- an output means which outputs operation beam having a function of making an incision on a cornea of an eye;
- a control means which controls at least an irradiating direction of said operation beam in such a manner as to form an incised site for inserting an intraocular lens into an interior of the eye, the incised site penetrating from an outer front surface of the cornea of the eye to an inner front surface, by the operation beam output from the output means;
- and
- a setting means which sets a cross sectional shape in a direction intersecting an advancing direction from an opening of the outer front surface of the cornea in said incised site toward an opening of the inner front surface, to the other linear shape than a rectilinear shape in which a convex shape collapsing onto the inner front surface from the outer front surface of the cornea is formed at least in one of both sides of said incised site, in the case of inserting the intraocular lens through said incised site, and accepts an input from a user,
- wherein said setting means comprises:
- a display means which displays an image of an operation part;
- and
- a superposition setting means which superposes the image of the operation part displayed by the display means, and accepts an input setting a shape of an advancing route heading for the inner front surface from the outer front surface of the cornea of the eye in the incised site, and a cross sectional shape in a direction intersecting said advancing route in the incised site, and
- wherein said superposition setting means can accept a cross sectional shape in which said cross sectional shape changes in correspondence to the position on said advancing route in the incised site.
