This was a pilot study designed to investigate the use of ellipsoidal hard contact lenses for use in Orthokeratology. The elliptical lens design generally gave subjective comfort while providing an optimum fit objectively. Favorable Orthokeratological changes were produced with elliptical lenses without the induction of unwanted with-the-rule astigmatism. Recommendations for future investigations are made and a set of guidlines for a simple approach to Orthokeratology is presented.
