Empirical fitting with polycon II lenses

Abstract

Historically, rigid gas permeable (RGP) lens parameters have been determined through trial fitting. Nevertheless, practitioners would likely welcome the opportunity to empirically fit RGP lenses if they could be confident of the outcome. This clinical investigation sought to evaluate the potential success of empirically fitting 9.0 mm Polycon II lenses. Based on both objective and subjective outcomes, this study suggests that empirically fitting the larger 9.5 mm Polycon II design, in combination with a lid attachment approach, would yield greater initial patient satisfaction.
