Two fundus lenses, a 90-diopter preset lens and a 58.6-diopter El Bayadi-Kajiura lens, were compared. The lenses were evaluated with regard to their optics, magnification, field of view, and photographic usefulness in photographing the posterior vitreous. The 90-diopter lens provided a wider field of view but lower magnification. Both lenses permitted high-quality vitreous photographs through the slit lamp, but the 90-diopter lens allowed photographs to be taken through small pupils and some lens opacities.
对两个眼底透镜进行了比较，一个是90屈光度的预设透镜，另一个是58.6屈光度的埃尔·巴亚迪-卡久拉透镜。从光学性能、放大倍数、视野以及在拍摄玻璃体后部时的摄影实用性等方面对这些透镜进行了评估。90屈光度的透镜提供了更宽的视野，但放大倍数较低。两个透镜都能通过裂隙灯获得高质量的玻璃体照片，但90屈光度的透镜允许在小瞳孔和一些晶状体混浊的情况下拍摄照片。
