Abstract: The present invention relates to an ophthalmic treatment device and a control method improved so as to minimize the treatment time. The ophthalmic treatment device comprise a beam-generating unit for generating a therapeutic beam, a beam-delivery unit for guiding the therapeutic beam to an eyeball, an image unit generating an image of an eyeball to be treated and displaying the image of the eyeball, a pattern unit allowing a predetermined pattern shape to overlie a diseased image area in the image of the eyeball, and an input unit which selects an irradiation position for the therapeutic beam by applying an input signal in such a way as to selectively set a pattern shape overlying either the inside of the diseased portion or the outside of the diseased portion, based on a disease image outline profile.
