This invention provides a high efficient corneal therapy system using UV and blue light collagen cross-link. The said UV-blue therapy system consists of a control panel, a power supply, and a light source. The output light of the said light source is delivered to the treated cornea via an optical set and having a spot size of 7 to 15 mm. The said light source can be a LED or a diode laser having a wavelength range of 340 to 480 nm, power of 3 mW to 500 mW. The said UV-blue therapy system can also consists of multiple channels. It can also consists of a fixation post set consisting of a pair of posts, or a standing-light soft-post, or an M-shape post. The output light can be a single wavelength (340-480 nm) or a dual wavelength combining (340-380) nm and (381-480) nm. The said UV-blue therapy system may be used for keratoconus and also used to stabilize the cornea surface curvature after a laser vision correction.一種使用紫藍光(UV-blue light)交聯(crosslink)作用之高效率角膜光療儀。該紫藍光療儀包括一控制面板顯示,一電源器以及一光源器,該光源器輸出光經由一光學鏡片組控制其在角膜光療部位光斑直徑(7到15毫米)。該光源器可為LED或半導體雷射,波長340到480奈米,輸出功率3毫瓦到500毫瓦。該紫藍光療儀也可多管道輸出,也可包括一個固定支架其組成包括:一根垂直及一橫向支架,立燈軟管支架或一個M形支架。該輸出光可為單一波長(340到480奈米)或雙波長。該雙波長可為340到380奈米以及381到480奈米之組合。該紫藍光角膜光療儀可使用於治療角膜角椎(keratoconus),也可使用於穩定雷射視力校正術後角膜表面曲率。(10)‧‧‧電源器(11,12)‧‧‧面板控制顯示(13)‧‧‧手動開關(14)‧‧‧腳踏開關(15)‧‧‧電源線(20)‧‧‧光源器(30)‧‧‧光學鏡片組
