[Endothelial effects of radial keratotomy in a non-human primate]

The study of the endothelial repercussion of radial keratotomy has been done on 33 corneas of 21 non human primates, using Scanning Electronic Microscope. Various lesions has been observed; the relationship between these lesions and the surgery parameters have been studied. One can conclude that the lesions are constant; their severity is related to the number and the depth of the incisions; as for their evolution, they do not seem to worsen with time during the experimental study (1 hour to 18 months).
