While preventing the complication which is pulled up by heating the eyeball, while as it irradiates in order to raise the curative effect, it cools laser light at the laser strength which is stronger and the eyeball, the cornea edema lighten making, it offers the ophthalmology laser remedy instrument tool which makes that it irradiates laser light possible.The optical transmitted component leading laser light to the eyeball (lens 3) with, eyeball 2 and the optical transmitted component (lens 3) with between, the specified space (the cooling room 13) the spacer in order to form (cooling room formation department 14) with it had, by the fact that the fluid which is supplied to the cooling room 13 is minded, it made the eyeball which is in the midst of laser irradiating the constitution which is made cooling possible.眼球の加熱により引き起こされる合併症を予防しながら、より強いレーザー強度でレーザー光を照射し治療効果を高めるため、眼球を冷却するとともに、角膜浮腫を軽減させながらレーザー光の照射を行うことを可能とする眼科レーザー治療用器具を提供する。レーザー光を眼球に導く光透過部材(レンズ3)と、眼球2と光透過部材(レンズ3)との間に、所定の空間(冷却室13)を形成するためのスペーサ(冷却室形成部14)とを備え、冷却室13に供給された流体を介することで、レーザー照射中の眼球を冷却可能とする構成とした。
