Injury Effects of Lasers on Eyes

The injurious effects of different wavelength laser with various operating mode and exposure doses on eyes were reported. Comparison of laser damage effects on eyes was conducted between rabbits with different extent of pigment. The ratio of laser damage threshold for eyes of rabbit, monkey to the yellow race was also discussed. The eye is an imaging system sensitive to light. An incident laser beam can form an image in a very small retinal area so that the dosage (irradiance or illumination) increases by four to five orders of magnitude; very little incidence can cause serious injuries. Therefore, the emergence of the laser brings about a new topic on medical research into eye effects from exposure to lasers. Trans. of Jiguang Jishu (Laser Technology) (China) v12 n6 p49-53 Dec 88.
