Changing the base curve is not required to increase/decrease corneal clearance. The rest of the parameters will remain the same, as well as the fitting relationship in those locations. Final Outcome The parameters of the final lenses are listed in Table 1. He elected to continue monovision. The acuity was 20/20 -2 OD and 20/70 OS at dis- tance (over-refraction -1.75 yielded 20/25) and 20/25 at near. He appre- ciated the clarity in vision, and he denied removing lenses throughout the day to make them comfortable. The nasal and temporal view of his final lens on OD is shown dem- onstrating the location of the edge relative to his pinguecula (Figures 1 and 2). When reviewing his overall case, he is a presbyopic-hyperope with a large HVID and keratoconus; each sclera demonstrates at least 180 microns of with-the-rule toricity at a 16-mm chord.
