APPARATUS FOR RETINA PHOTOTHERAPY

A process for using a retinal photostimulation device involves limiting multiple or repeated uses of the device during a particular treatment cycle. Ordinarily a physician would not want to repeat multiple photostimulation treatments on a patient in a short period time. The process would prevent such retreatment during a single treatment cycle where the retina for any subsequent treatment biometrically matches the retina for an earlier treatment. Such subsequent treatments would be permitted within a predefined period of time after the earlier treatment. Such subsequent treatment may also be permitted where the retinas do not biometrically match.
