Description

This instrument has 19 lenses in a single disc with no auxiliary disc. It features a 6-volt lamp on resistance, which produced increased illumination. This enabled better observation of the fundus in the presence of incipient cataracts or cloudy media. It was also helpful in the finding of holes in retinal detachment. The instrument was excellent for indirect ophthalmoscopy.
