氪激光与氩激光的区别,前者波长为647.1nm的红光束,后者波长为488.0和514.5nm蓝绿光束。因此,理论上氪激光没有什么能量被血红蛋白吸收,不能直接用于视网膜血管的凝固。患者为糖尿病性视网膜病变,新生血管累及到视乳头,视力6/9或以上,随机抽样选用氩激光器和氪激光治疗。视乳头新生血管等级按Hammersmith分类法分类,采取全视网膜光凝技 The difference between krypton laser and argon laser, the former wavelength of 647.1nm red beam, the latter wavelength of 488.0 and 514.5nm blue-green beam. Therefore, in theory, there is no krypton laser energy absorbed by hemoglobin, can not be directly used for retinal vascular coagulation. Patients with diabetic retinopathy, neovascularization involving the optic nerve, visual acuity 6/9 or more, a random sample of argon laser and krypton laser treatment. Optic neovascularization was classified according to the Hammersmith classification and was treated with panretinal photocoagulation
