Abstract
A light-permeable member (lens 3) is provided to lead laser beams to an eyeball (2), and a spacer member (refrigerator forming portion 14) is provided to maintain a predetermined space (refrigerator chamber 13) between the light-permeable member (lens 3) and the eyeball (2). The eyeball (2) is cooled by introducing a fluid into the space (refrigerator chamber 13) so as to cool the eyeball (2) while applying the laser beams to the eyeball (2). The laser beams of higher intensity is applied with an occurrence of keratoedema reduced, while at the same time, preventing the complication which otherwise would be caused due to the heat generation of the eyeball (2).
