Abstract
A laser treatment apparatus provided with a light delivery optical system for delivering a laser beam for treatment from a laser source to a treatment area of a patient's eye to irradiate the treatment area is disclosed. The light delivery optical system includes a homogenizer optical system which substantially uniformizes an energy distribution of the laser beam; a relay optical system having lenses for relaying an image of an exit end face of the homogenizer optical system onto the treatment area; and a distortion generating optical system which is disposed between the homogenizer optical system and the relay optical system and generates a negative distortion in the exit end face image to be formed on the treatment area.

A laser treatment apparatus provided with a light delivery optical system for delivering a laser beam for treatment from a laser source to a treatment area of a patient's eye to irradiate the treatment area, the light delivery optical system including:
- an optical fiber for delivering the laser beam from the laser source;
- a distortion generating optical system which forms an image of an exit end face of the optical fiber and generates a negative distortion in the exit end face image to be formed on the treatment area;
- and
- a relay optical system which forms an image of the exit end face formed by the distortion generating optical system on the treatment area.
