title: [Corneal curvature of myopia].
abstract: We classified myopia by total refractive error, measured the corneal curvature, and analyzed the relationship between the diopter value and corneal curvature in growing teen-agers and in adults in their twenties, whose myopic progress is presumed to have stopped. We adopted as the harmonic average the central 3.0 mm of the cornea. We also examined peripheral corneal curvature in upper side, lower side, temporal side and nasal side at about 4.5 mm and 6.5 mm diameter from the center. There was very little difference in the harmonic average of corneal curvature from -1D to -6D. Similarly, there was very little difference in the peripheral corneal curvature. The corneal curvature was larger from central to periphery in all directions. The upper side was larger than lower side and the nasal side was larger than the temporal side. We concluded that the refractive power did not depend on the corneal refractive power in mild to moderate myopic patients.
