对应用低强度氦-氖激光照射综合治疗512人角膜穿通伤、烧伤、溃疡和继发性角膜内皮-上皮病变结果的分析表明,该疗法可以显著提高疗效,缩短炎症过程和加快上皮形成。氦-氖激光照射角膜,辐射通量功率密度为50～100μW/cm~2。6～10次为一疗程,每日一次,每次照射3分钟。对照组用传统治疗方法,未用激光。采用重量50mg/mm~2的痛觉测量计检测角膜相对敏感度,计算炎症平息、上皮形成时间及视功能状况和病人住院时间等,来评定治疗效果。观察角膜穿通伤217人,其中单纯穿通伤123人;伴晶体损伤39人;伴晶体损伤和眼内
The results of comprehensive treatment of 512 corneal penetrating injuries, burns, ulcers and secondary corneal endothelial-epithelial lesions with low-intensity He-Ne laser irradiation show that the therapy can significantly improve the curative effect, shorten the inflammatory process and accelerate the epithelial formation. The cornea is irradiated with helium-neon laser, and the power density of the radiation flux is 50-100 μW / cm -2.6~10 times for one treatment once daily for 3 minutes. The control group with the traditional treatment methods, no laser. The relative sensitivities of the cornea were measured with a pain relief measuring instrument weighing 50 mg / mm ~ 2, the inflammation subsidence, the time of epithelialization, the visual function and patient’s hospitalization time were calculated to evaluate the therapeutic effect. 217 corneal penetrating wounds were observed, of which 123 were penetrating wounds alone; 39 were accompanied by lens damage; those with lens injury and intraocular
