PROBLEM TO BE SOLVED: To provide a technology for making it possible to surely illuminate a part to be observed in laser treatment in an ophthalmology field.SOLUTION: A laser treatment system according to an embodiment includes an illumination optical system, observation optical system, irradiation optical system, interference optical system, optical path synthesis means, optical scan means, and control means. The illumination optical system illuminates an eye of a patient. The observation optical system is used for observing the illuminated eye of the patient. The irradiation optical system irradiates the eye of the patient with collimation light and treatment laser light. The interference optical system splits light from a light source into measurement light and reference light; and leads interference light obtained by superposing the measurement light returned from the eye of the patient on the reference light, to detection means. The optical path synthesis means combines an optical path of the illumination optical system, an optical path of the irradiation optical system, and an optical path of the measurement light so as to substantially have the same axis. The optical scan means is provided at a position closer to the eye of the patient than a position obtained by combining the optical path of the irradiation optical system and the optical path of the measurement light. The control means controls the irradiation optical system, interference optical system, and optical scan means. |
