K-study

Temporal keratometry is an additional test not done in a routine contact lens fitting. Temporal keratometry is measured to help predict the amount of myopia reduction that can be obtained through fitting a patient with orthokeratology.l The purpose of this study is to investigate the temporal keratometry measurement used when fitting orthokeratology. By comparing the temporal keratometry measurements taken on a conventional Bausch and Lomb keratometer to temporal measurements done on the EyeSys corneal topographer. The computer assisted topographer was chosen because other studies have shown the topographer to be very similar in central curvature readings and even more descriptive in peripheral curvature readings.
