Description

レーザ光源から出射されたレーザ光を３次元的に走査させる走査光学系を備え、予め設定された治療領域に対応する各ターゲット位置にレーザ光を照射して患者眼の処置を行うための眼科用レーザ手術装置であって、前記患者眼の水晶体を含む前記治療領域を予めプランニングするために取得された前記患者眼の構造に関する第１のデータセットと、前記治療領域がプランニングされた後、プランニングされた治療領域に基づいて前記レーザ光による処置を行う際に取得された前記患者眼の構造に関する第２のデータセットと、を取得し、前記第１のデータセットと前記第２のデータセットとを比較し、前記患者眼の構造変化情報、前記患者眼の視線方向の変化情報の少なくともいずれかである前記患者眼の変化情報を得る変化情報取得手段を備えることを特徴とする。 It includes a laser beam emitted from Les chromatography The light source 3 dimensionally scanned to the scanning optical system, for performing the treatment of patients eye by irradiating a laser beam to each target position corresponding to the predetermined treatment area a ophthalmic laser surgical device, a first data set relating to the structure of the patient's eye acquired in order to advance planning the treatment area including the lens of the patient's eye, after the treatment region is planning , planning has been based on the treated area acquires a second data set about the structure of the patient's eye that is obtained when performing treatment with the laser beam, said first data set and said second data comparing the set, structural change information of the patient's eye, the change-information obtaining means for obtaining at least change the information of the patient's eye is either gaze direction of the change information of the patient's eye Characterized in that it comprises.

Claims

The laser beam emitted from the laser light source includes a three-dimensionally scanned to the scanning optical system, ophthalmology for performing a treatment of patients eye by irradiating a laser beam to each target position corresponding to the predetermined treatment area Laser surgical device for
A first data set relating to the structure of the patient's eye acquired in order to advance planning the treatment area including the lens of the patient's eye, after said treatment area is planning on the basis of the treatment area that is planning a second data set about the structure of the patient's eye that is obtained when performing the treatment by the laser beam, the acquired
Comparing the second data set and the first data set, change to obtain the structure change information of the patient's eye, at least the change information of the patient's eye is either gaze direction of the change information of the patient's eye An ophthalmic laser surgical apparatus comprising an information acquisition unit.

A fixation guidance unit for moving the fixation position of the fixation target to be presented to the patient's eye and guiding the fixation direction of the patient's eye;
Viewing direction of the patient's eye relative to when the fixation induction unit to control and acquire the first data set to be used for planning based on the line-of-sight direction of the change information of the patient's eye acquired by the change information acquiring unit and control means for correcting the variation of further ophthalmic laser surgical apparatus according to claim 1, characterized in that it comprises.

Comprising said treatment area that is planning on the basis of the first data set, and change information of the patient's eye acquired by the change information acquiring unit, a setting means for setting an irradiation position of the laser beam on the basis of The ophthalmic laser surgical apparatus according to claim 1 or 2.
