title: Orthokeratology: changes to the corneal curvature and the effect on refractive power due to the sagittal length change.
abstract: Little has been published to date on orthokeratology which can explain what changes the eye actually goes through. Many professionals are waiting for this evidence before judging this controversial technique. With orthokeratology the corneal curves are changed and present a definite pattern. There are a number of changes which must occur when the cornea is flattened which reduce the power of the eye beyond that amount of flattening. This paper examines one of these unknowns.
