The major methods of determining corneal thickness are briefly reviewed. Theoretical expressions are derived for the relative error in the climate of corneal thickness, in terms of the errors in such parameters as the assumed radius of curvature and refractive index of the cornea. The relevance of these results to practical studies of corneal‐thickness, variation is discussed.
