摘　　要：波长介于1．3～1．4μm范围内的近红外（ NIR）激光是眼损伤敏感部位由视网膜向角膜转换的过渡区。近年来，激光技术的突破使得该光谱区激光不但种类增多而且输出功率大大提高，其眼损伤效应受到高度关注。由于该波段激光具有“体吸收”特点，其眼损伤效应与可见光和中远红外光相比具有很多独特的特点和影响因素。该文对“过渡区”NIR激光眼损伤效应、影响因素及存在问题进行了综述和分析。The transitional near-infrared （NIR） laser was defined as ranging from 1.3 μm to 1.4 μm, within which the most sensitive tissue to laser damage changed from the retina to the cornea. The ocular damage effect has attracted much attention due to the increased varieties and output power of laser in this spectrum region in recent years. Compared with visible and mid-and-far infrared wavelengths, the ocular damage effect induced by transitional NIR wavelengths has many peculiarities and impact factors due to the ＂ bulk absorption＂ by ocular media. This paper reviews the existing ocular damage threshold data and analyzes the characteristics, impact factors and unresolved issues relating to ocular effects induced by laser radiation over the transition zone.
