Rigid gas permeable lenses.

摘要

A method of fitting rigid gas permeable contact lenses comprising the steps of: providing a set of lenses of differing BCOR values, but the same optical corrective power; fitting a patient with a lens to determine an acceptable BCOR value for the patient; determining the corrective prescription for that patient; and supplying the patient with a lens having an acceptable BCOR value and the correct prescription. The lens supplied is manufactured in the same geometry and fitting characteristics as the lens from the set used in fitting and adjusted to the correct prescription power from the fixed power by diffractive means. <IMAGE>
