Six subjects were chosen to evaluate the peripheral edge fits of the traditional jive zone orthokeratology lens with a second alignment curve fitted to the cornea and a new jive zone orthokeratology lens with a flattened second alignment curve. The lenses were ordered with parameters calculated from the Humphrey Atlas Computed Corneal Topographer and the OrthoTools software program. Second alignment and peripheral curve fittings were evaluated with sodium fluorescein and videotaped. The study shows all six subjects showed an increased peripheral edge clearance with modified lens design as compared to the traditional/ens design.
