最初的动物实验以及对因事故而受损的人的观察表明,激光辐照对视觉器官危害特别大。实验证明,热作用是激光射线作用时导致组织损伤(包括眼)的最典型效应,它与普通热源的热作用很相似,因二者导致同样的加热效果,但激光的热效应有其某些固有的特点,尤其表现在激光脉冲辐照对机体的作用上,激光热作用的特点主要由激光脉冲性决定。当组织特别是视网膜受辐照时,发生瞬时加温,形成蒸气,加大气压,产生冲击波,由于组织受机械损伤,冲击波使激光的辐照热作用加剧。所以激光脉冲辐照对眼底组织不仅致烧伤,
Initial animal experiments, as well as observations of people who were damaged as a result of the accident, show that laser irradiation is particularly damaging to the visual organ. Experiments have shown that the thermal effect is the most typical effect that leads to tissue damage (including the eye) when irradiated by a laser beam. The thermal effect is very similar to that of a normal heat source because both result in the same heating effect, but the thermal effects of the laser have some inherent The characteristics of the laser pulse irradiation in particular on the role of the body, the main characteristics of laser heat pulse laser sex decision. When the tissue, especially the retina, is irradiated, instantaneous heating occurs, vapor is formed, the air pressure is increased, and shock waves are generated. As the tissue is mechanically damaged, the shock wave intensifies the irradiation heat of the laser. Therefore, laser pulse irradiation not only cause burns to the fundus,
