| 摘 要： | 用连续CO_2激光器,照射青紫蓝灰兔眼142只.求得平均照射时间1.03秒,角膜损伤阈值ED_(50)(?)5.72W/cm~2(95%可信限5.58～5.85W/cm~2);平均照射0.12秒,ED_(50)(?)10.7W/cm~2(95%可信限10.4～10.9W/cm~2).

Injury threshold of cornea by CO2 laser light exposure |
| |
| Abstract: | The minimal visible lesion in the corneal epithelium resulted from exposure to C02 laser light has been carefully determined. The dose to cause 50% damage probability (ED50) varied with time of exposure: for 1.03 s was 5.72 W/cm2 (95% GL 5.8~5.85 W/cm2) and for 0.12 s was 10.7 W/cm2 (95% CL 10.4~10.9 W/cm2). |
