【摘要】 <正> 紫外激光对眼的损伤部位及损伤程度,随其波长、照射时间而不同。因而在现有的激光安全标准中,远紫外与近紫外激光的辐照限值均有所不同。但迄今为止,有关308nm波段纳秒级脉冲紫外激光生物效应报道很少。本文给出XeCl准分子紫外激光对角膜的损伤阈值,供制订有关的激光安全标更多还原

【Abstract】 Ocular dose reponse relationship was experimentally determined by exposing chinchilla rabbit eyes to XeCl excimer laser light at 308 nm. The eorneal damage threshold ED59 (effective dose for 0.5 probability of producing a biomieroscopically visible eorneal lesion) was found to be 0.83 J/cm2(95% C. L. was 0.749-0.911 J/cm2) .更多还原
