AIM
To evaluate the ability of various laser wavelengths in delivering sufficient burns to the retina in eyes with cataract using a new multicolor pattern scan laser with green (532 nm), yellow (577 nm), and red (647 nm) lasers.
METHODS
The relationship between the Emery-Little (EL) degree of cataract severity and the laser wavelength required to deliver adequate burns was investigated in 102 diabetic eyes. Treatment time, total number of laser shots, and intra-operative pain were assessed as well.
RESULTS
All EL-1 grade eyes and 50% of EL-2 eyes were successfully treated with the green laser, while 50% of EL-2 eyes, 96% of EL-3 eyes, and 50% of EL-4 eyes required the yellow laser. The red laser was effective in the remaining 4% of EL-3 and 50% of EL-4 eyes.
CONCLUSION
Longer wavelength lasers are more effective in delivering laser burns through cataract when we use a multicolor pattern scan laser system.
目的
使用一种新型的具有绿色（532纳米）、黄色（577纳米）和红色（647纳米）激光的多色图案扫描激光，评估不同激光波长在白内障眼中对视网膜造成足够灼伤的能力。
方法
在102只糖尿病患者眼中，研究了埃默里 - 利特尔（EL）白内障严重程度分级与造成足够灼伤所需激光波长之间的关系。还评估了治疗时间、激光照射总次数和术中疼痛情况。
结果
所有EL - 1级眼和50%的EL - 2级眼用绿色激光成功治疗，而50%的EL - 2级眼、96%的EL - 3级眼和50%的EL - 4级眼需要黄色激光。红色激光对其余4%的EL - 3级眼和50%的EL - 4级眼有效。
结论
当我们使用多色图案扫描激光系统时，较长波长的激光在透过白内障造成激光灼伤方面更有效。
