PROBLEM TO BE SOLVED: To provide a microscope for ophthalmic surgery having a high freedom degree in arrangement of a drive system for moving an optical member, capable of observing a patients eye and acquiring an OCT image.SOLUTION: The microscope for ophthalmic surgery includes an illumination optical system, an observation optical system, an interference optical system, an optical scanner, a collimator lens, an optical fiber, and a moving mechanism. The illumination optical system illuminates the patients eye with illumination light. The observation optical system is used for observing a patients eye illuminated by the illumination optical system. The interference optical system splits light from a light source into measurement light and reference light, and detects interference light of return light of the measurement light from the subjects eye and the reference light. The optical scanner is disposed at an optical path of the measurement light. The collimator lens is disposed between the light source and the optical scanner. The optical fiber is so disposed as to place an outgoing end of the measurement light at a position facing the collimator lens. The moving mechanism moves the collimator lens and the outgoing end relative to each other along the optical path of the measurement light.SELECTED DRAWING: Figure 2COPYRIGHT: (C)2017,JPO&INPIT【課題】光学部材を移動させる駆動系の配置の自由度が高く、患者眼の観察とOCT画像の取得が可能な眼科手術用顕微鏡を提供する。【解決手段】眼科手術用顕微鏡は、照明光学系と、観察光学系と、干渉光学系と、光スキャナと、コリメートレンズと、光ファイバと、移動機構とを含む。照明光学系は、照明光で患者眼を照明する。観察光学系は、照明光学系により照明されている患者眼を観察するために用いられる。干渉光学系は、光源からの光を測定光と参照光とに分割し、患者眼からの測定光の戻り光と参照光との干渉光を検出する。光スキャナは、測定光の光路に配置される。コリメートレンズは、光源と光スキャナとの間に配置される。光ファイバは、コリメートレンズに臨む位置に測定光の出射端が配置される。移動機構は、コリメートレンズと出射端とを測定光の光路に沿って相対的に移動する。【選択図】図2
