Abstract
An ophthalmic laser treatment apparatus which irradiates a laser beam to a patient's eye to be treated is disclosed. The apparatus includes: a first optical fiber which delivers a first laser beam emitted from a first laser source; a first light delivery optical system which forms an image of an emission end surface of the first optical fiber on the affected part of the eye in a predetermined first spot size being in a range of 50 μm to 1000 μm; a second optical fiber which delivers a second laser beam emitted from a second laser source; and a second light delivery optical system which forms an image of an emission end surface of the second optical fiber on the affected part of the eye in a predetermined second spot size in a range of 500 μm to 7000 μm.
