This paper is concerned with corneal blindness and the possibility of restoring image perception in cases of corneal scarring.

Experiments in this field gave me reason to believe that a new approach may be possible in the production of images.

For this study I made a light-proof telescopic sliding tube with a length varying between 10 and 35 cm., with a diameter of 25 mm., both ends covered with black mastic tape, with a 10 mm. round opening at each end.

I had two completely opaque human corneas and two cataractous lenses at my disposal, removed by surgery.

The corneas were kept in a slightly hypertonic alkaline Ringer's solution in which they were well preserved for a few weeks. One side of a clear, thin coverglass was first precoated with sodium silicate binder and then an ultraviolet sensitive zinc sulfide phosphorescent powder was blown on by a hot air blast.
