三、影响激光治疗眼病效果的一些因素 (一)选择合适波长的激光不同部位、不同目的,要求使用不同波长激光。例如,行激光虹膜切除术,氩、氪、红宝石激光都有效,但常用氩激光,因其功率高,而且对血管有直接光凝固止血作用。但与近年来发展的Q开关钕钇铝石榴石(Nd:YAG)激光比较,后者比氩激光要好,更易击穿虹膜,且虹膜孔不易再闭合。应用Nd:YAG激光行虹膜切除时有时可发生虹膜出血,大部分出血可自行停止或术中略压接触镜即可止血,不影响预后:只有极少数出血须中断激光治疗,待出血吸收或移动位置后再行治疗。因此目前绝大多数人喜用Q开关Nd:YAG激光行虹膜切除术。
Third, the impact of laser treatment of eye diseases, some of the factors (a) choose the appropriate wavelength of laser in different parts of different purposes, require the use of different wavelengths of laser. For example, the line laser iridectomy, argon, krypton, ruby laser are effective, but commonly used argon laser, because of its high power, but also direct photocoagulation of blood vessels to stop bleeding. However, compared with Q-switched neodymium-yttrium aluminum garnet (Nd: YAG) laser developed in recent years, the latter is better than argon laser and the iris is easier to be punctured, and the iris hole is hard to be closed again. Application of Nd: YAG laser iris resection iris bleeding sometimes occurs, most of the bleeding can stop on their own or slightly pressure during surgery to stop bleeding, does not affect the prognosis: only a very small number of bleeding to be interrupted laser treatment until the bleeding absorption or moving position After treatment. Therefore, most people like to use Q switch Nd: YAG laser iris resection.
