title: Research in orthokeratology. Part III: results and observations.
abstract: The effects of contact lenses, fitted by defined conventional and orthokeratological techniques, are given and compared to a group of non-contact lens wearers. Data presented include changes in corneal curvature, topography, refraction and astigmatism. General trends and variability of data are discussed in conjunction with pertinent clinical observations for the three test groups.
