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.
