一般应用的氪激光具有三种波长,即氪红(647.1nm)、氪黄(568.2nm)和氪绿(514.5nm)。应用氪红的光凝治疗近来已受到临床方面的极大关注,但氪黄在临床方面仍较少受到注意。其实,氪红和氪黄在光凝治疗方面各有其自己的优点,最有效的氪激光临床应用应该是氪红和氪黄两种波长优点的结合。氪激光两种波长的光凝术之组织学研究已证实了这一点。作者认为:根据组织学研究的结果,为了增加光凝治疗在眼科方面的安全性和有效性,目前应用的光凝器必须具有自动化的性能。组织学研究的实验是在一种猴的眼球上进行,以激光光凝损伤不超出视网膜色素上皮层和感光细胞层、而视网暎神经纤维层和脉络膜玻璃膜(Bruch膜)完好无损为良好治疗效果。先以光斑大小均为100μm的氪红投射到猴
Commonly used krypton lasers have three wavelengths, krypton red (647.1 nm), krypton yellow (568.2 nm) and krypton green (514.5 nm). The application of krypton red photocoagulation has drawn considerable clinical attention recently, but krypton yellow is still less clinically relevant. In fact, krypton red and krypton yellow in the photocoagulation treatment has its own advantages, the most effective clinical application of krypton laser krypton red and krypton yellow should be the combination of two wavelength advantages. Histological studies of krypton laser photocoagulation at two wavelengths have confirmed this. According to the authors, according to the results of histological studies, in order to increase the ophthalmological safety and efficacy of photocoagulation, the currently available photocoagulators must have automated properties. Histological studies were performed on the eyes of a monkeys to laser photocoagulation damage does not exceed the retinal pigment epithelium and photoreceptor cell layer, and retinal reflex nerve fiber layer and choroidal glass membrane (Bruch film) intact as good treatment effect. The first krypton red with 100 μm spot size was projected onto the monkey
