| Fluorophotometry has
been used in research on contact lenses almost from the beginning. A number of very useful
fluorophotometric techniques have been developed which may be used to evaluate the
condition of the eye following contact lens wear. Today, I will concentrate on three of these applications that we
feel are of particular interest in evaluating the safety of extended wear contact lens
designs. The applications that I will cover are corneal pH, tear turn-over under
the contact lens and cornea epithelial permeability. |
