Corneal radius of curvature in emmetropic Thai people.

The corneal radius of curvature of 110 emmetropic Thai people from the out-patient section, Department of Ophthlmology was measured by keratometer, male 37, female 73, age 14-58 years, the mean corneal radius of curvature right eye in the vertical meridian = 7.612+0.264 mm., in the horizontal meridian = 7.726+0.257 mm., left eye in the vertical meridian = 7.610+0.269 mm., in the horizontal meridian = 7.733+0.269 mm. These corneal curvature value in Thai people were more curve than that of the European and American eye. This assume that the dimension of the Thai eye are smaller than those of the European and American eye.
