Preliminary study of keratomileusis in primates (Macaca speciosa)

Keratomileusis was investigated in five stumptail monkey eyes (Macaca speciosa). An arbitrary flattening of six diopters was selected and programmed in the computer for each eye. The actual flattening achieved two weeks after surgery ranged from -4.00 D to -6.00 diopters (D). One to 5 diopters of the initial effect was lost during the six-month observation period. Histopathology of two eyes demonstrated attenuation and/or loss of Bowman's membrane with overlying epithelial defects.
