The use of fluorescein patterns as a guide in fitting rigid gas permeable contact lenses

Abstract

The fitting of Rigid Gas Permeable contact lenses is a process that is not complete without a final "lens on• evaluation of overall fit. For a great majority of practitioners, this evaluation involves observing fluorescein pooling patterns underneath the contact lens using cobalt blue light. To gain confidence in correctly interpreting these patterns, a great many lens fitting patterns need to be seen. We feel that there is a great need for a simple yet thorough compilation of fluorescein pattern photographs that can be used as a teaching supplement both in classroom and clinic to show how changing lens parameters
