PROBLEM TO BE SOLVED: To suitably perform a docking process.SOLUTION: Provided is an ophthalmic laser surgery device comprising an irradiation optical system for treating a patients eye fixed by an eyeball fixation unit. The ophthalmic laser surgery device comprises a tomographic image acquisition section comprising an OCT light source, a measurement light path, a reference light path, a photo detector for detecting a signal generated by interference between measurement light guided by the patients eye and reference light from the reference light path, and an image processor for obtaining a tomographic image by processing the interference signal. The reference light path comprises: a first reference optical system having a light path length set for obtaining a tomographic image of the patients eye and a second reference optical system having a light path length set for obtaining a tomographic image of an interface. The image processor performs: first processing for removing one of a real image and a virtual image obtained by processing an interference signal between the measurement light guided by the patients eye and reference light of the first reference optical system and second processing for removing one of a real image and a virtual image obtained by processing an interference signal between a measurement light guided by the interface and reference light of the second reference optical system.COPYRIGHT: (C)2016,JPO&INPIT【課題】 ドッキング工程を好適に行う。【解決手段】 照射光学系を備え、眼球固定ユニットによって固定された患者眼を処置する眼科用レーザ手術装置であって、OCT光源と、測定光路と、参照光路と、患者眼に導かれた測定光と参照光路からの参照光との干渉信号を検出する光検出器と、干渉信号を処理して断層画像を得る画像処理器と、を備える断層画像取得部を備え、参照光路は、患者眼の断層画像を得るために光路長が設定された第1参照光学系と、インターフェースの断層画像を得るために光路長が設定された第2参照光学系と、を備え、画像処理器は、患者眼に導かれた測定光と第1参照光学系の参照光との干渉信号を処理した実像及び虚像の一方を除去する第1の処理と、インターフェースに導かれた測定光と第2参照光学系の参照光との干渉信号を処理した実像及び虚像の一方を除去する第2の処理を行う。【選択図】 図6
