Videokeratoscopy in contact lens practice

Videokeratoscopy is an important addition to contact lens practice, where a better understanding of corneal contour obviously helps the practitioner to achieve an optimal fitting relationship between the contact lens and the cornea. A variety of topographical maps, encompassing a large range of corneal conditions, are presented in this study to illustrate the different corneal contours the contact lens clinician is likely to encounter in practice. Interpretation of these corneal maps is outlined, with an emphasis on how one determines the appropriate contact lens fitting strategy based on the videokeratoscopic image.
