摘要： PURPOSE: To reduce the dispersion of tight beams passing through the sclera to increase the transmission of the light beams by compressing the sclera with a projecting element located on the emitting surface of a lens, and reducing the thickness of the sclera at a position where the light beams pass. CONSTITUTION: This contact lens has at least one optical lens 12 having the incident surface 22 of light beams 14 from a laser head TL and having a beam emitting surface 24 formed to make direct contact with the conjunctiva 7 or the sclera 1 of the eye to be treated, and includes a projecting element 18 of the same material as the lens 12, for compressing the sclera 1 to increase beam propagation by reducing the thickness of the part where the light beams 14 pass. When the sclera 1 is compressed by the projecting element 18 of the lens 12, the sclera 1 changes in thickness from E1 to E2 and supports the pressure applied, and fibers constituting the scleral tissue are aligned in a specific direction to remarkably reduce the dispersion of the light beams 14 passing through the sclera 1.

摘要： PURPOSE: To achieve a regular temperature gradient between a plate shaped structure and an external portion of a laser mounting part by selecting a different fluid and flow speed for each system of three cooling circulation systems by closely applying a cooling member to a cooling corresponding element. CONSTITUTION: Spaces 11a and 11b forming the outside of a side surface of a platelike structure 1 are filled with gas having a low thermal conduction coefficient such as nitrogen or air, and members shaped like a duct are fitted to rectangular openings 9a, 9b in holding plates 8a, 8b to form circulation spaces 13a, 13b for a cooling solution such as water and are fixed to external mounting plates 14a, 14b of a laser from the outside. Tubes 17a, 17b extend into each circulation space 13a, 13b where electrical discharge lamps 18a, 18b are disposed, around which circulation tubes 19a, 19b for the cooling solution are formed. Side lateral housings 20a, 20b are provided between respective holding plates 8a, 8b and respective external mounted plates 14a, 14b are provided to form channels 21a, 21b for circulation of the cooling solution such as water.
