This is a review of optical methods related to biomicroscopy and laser treatment of the posterior segment of the eye. Contact lenses can be used to observe optical structures and couple laser radiation into the eye for a vast range of conditions and techniques. A small laser spot size is indispensable for photodisruptive work, though this requires a large beam diameter at the pupil and therefore optical systems and techniques such as scleral indentation which maximize the pupillary beam diameter are preferred. For coagulation work the choice of beam focusing optics is crucial for optimum safety. Vitreous replacement can be used to change the refractive power of the eye and permit new combinations of treatment and optical systems. This review covers many aspects of laser irradiation of the eye. It should be clear that, with the multitude of different procedures and optical systems involved, the laser surgeon is faced with a daunting task in assessing and meeting safety limits.
这是一篇关于与生物显微镜检查及眼后段激光治疗相关的光学方法的综述。隐形眼镜可用于观察光学结构，并将激光辐射耦合到眼睛中，适用于多种情况和技术。对于光破坏工作而言，小光斑尺寸是必不可少的，不过这需要瞳孔处有较大的光束直径，因此诸如巩膜压陷等能使瞳孔光束直径最大化的光学系统和技术更受青睐。对于凝固工作，光束聚焦光学器件的选择对于最佳安全性至关重要。玻璃体置换可用于改变眼睛的屈光力，并允许治疗和光学系统有新的组合。这篇综述涵盖了眼睛激光照射的诸多方面。应当明确的是，由于涉及众多不同的程序和光学系统，激光外科医生在评估和达到安全限度方面面临艰巨任务。
