[Corneal asphericity in myopes].
OBJECTIVE
To study the variations of corneal asphericity in a population of myopic patients.


METHODS
One hundred consecutive myopic patients were included in this study. The EyeSys videokeratoscope was used to assess the corneal topography of these patients seeking refractive surgery. We compared the results of cycloplegic refractions with the values of the corneal asphericity and mean central keratometry.


RESULTS
Mean corneal asphericity was -0.09. Eighty per cent of the myopic patients had a prolate corneal contour, whereas 20% had an oblate corneal contour. No significant relationship was found between the corneal asphericity value and the mean keratometry value or the mean refractive error.


CONCLUSIONS
The mean corneal asphericity in our myopic population was -0.09. This is slightly more than previously reported data in similar studies. No statistically significant relationship was found between corneal asphericity, mean refractive error, and mean keratometry.
