作者对裂隙灯显微镜照射方法及摄影方法进行了改造,设计了晶状体导光照射法和照像机裂隙灯联接臂。这是较为客观、易于掌握的摄影记录方法,能较完满地显露TNT白内障的全貌,改变了以往用描绘或文字记述来记录晶状体浑浊的状况,较好地避免了人为的误差,有助于TNT白内障的研究工作。本法全部设备和材料,都可用国产品,费用低廉,方法简便,便于推广。 The authors modified the method of slit lamp microscopy and photographic methods, and designed the lens guided light irradiation method and the camera slit lamp connected arm. This is a more objective and easy-to-grasp photographic recording method, which can reveal the whole picture of TNT cataract more satisfactorily, and change the past state of depiction or textual record of lens opacity, better avoid human error, contribute to TNT Cataract research. All the equipment and materials of the Law are available for domestic products, which are low in cost, easy in method and convenient in promotion.
