Ophthalmic treatment apparatus and method for controlling same

An ophthalmic treatment apparatus, comprising:

• a beam generation unit for generating a therapeutic beam;
• a beam delivery unit for guiding the therapeutic beam into an eyeball;
• an image unit for generating an image of a lesion formed in a retinal region of the eyeball;
• and
• a control unit for controlling the beam generation unit and the beam delivery unit such that the therapeutic beam is sequentially irradiated onto intersecting points of a plurality of grid patterns provided on the lesion when the plurality of grid patterns are sequentially provided on the lesion such that that the plurality of grid patterns partially overlap each other on the lesion,
• wherein the control unit comprises:
• when one of the plurality of grid patterns is provided on the lesion, a first mode for controlling the beam generation unit and the beam delivery unit such that the therapeutic beam is irradiated onto intersecting points of the one of the plurality of grid patterns;
• and
• when another one of the plurality of grid patterns is provided to partially overlap the one of the plurality of grid patterns after the control unit is controlled in the first mode, a second mode for controlling the beam generation unit and the beam delivery unit such that the therapeutic beam is irradiated onto intersecting points of the other one of the plurality of grid patterns except intersecting points where the one of the plurality of grid patterns overlaps the other one of the plurality of grid patterns.

A method of controlling an ophthalmic treatment apparatus, the method comprising:

• generating an image of a retina region of an eyeball in a lateral direction of a plane of a focal spot onto which a therapeutic beam is irradiated;
• analyzing a curvature of the image of the retina region;
• providing a grid pattern corresponding to the analyzed curvature of the retina region to the retina region;
• and
• irradiating intersecting points of the grid pattern provided in the retina region corresponding to the curvature of the retina region with the therapeutic beam,
• wherein the providing comprises sequentially providing a plurality of grid patterns on a lesion formed in the retina region to partially overlap each other;
• and
• wherein the irradiating comprises irradiating intersecting points of the plurality of grid patterns with the therapeutic beam except intersecting points where the plurality of grid patterns overlap each other.
