Case # 1: SR 25-yo Asian medical student Current soft lens wearer: –OD Preference sphere –OS Preference Toric VA w/CL: OD 20/20, OS 20/50 unstable Unhappy with vision in her left eye Subjective Refraction: –OD x 005, 20/20 –OS x 175, 20/30 Biomicroscopy: unremarkable

Case #1: Corneal Topography

Right eye: Spherical GP Spherical GP Boston EO 7.90 / / 9.5 VA: 20/15

Left eye: Spherical vs. Bitoric Bitoric GP Spherical GP Boston EO 8.13 / / / 9.5 VA 20/25

Case #2: AT 39 yo Hispanic male salesman Wears soft torics: decreased VA and comfort, eyes are always red, has “oily tears” HVID 11.5 mm Keratometry: OD / 82 OS / 105 Refraction: OD x 167, 20/25+ OS x 13, 20/25+ Lens designs?
