Lenticular vs. Single-Cut For Low Plus RGP's

The fitting characteristics of +0.50 DS Fluoroperm 60 rigid gas permeable lenses in lenticular and single-cut forms of the same parameters were autokeratometry readings,
evaluated on twenty-two eyes. Using both lens types were fit "on K". Fluorescein patterns were then videotaped and the lens fit assessed. Results indicated the lenticular lens fit better than the single-cut on 13/22 eyes (59%). Either lens type was adequate on 5/22 eyes (23%). The lenticular did not provide an acceptable lens fit on 4/22 eyes (18%). There were no instances of the single-cut lens providing a better fit on an eye than the lenticular.
