Onefit Spotlight Case Report: Custom Onefit™ MED with Toric Haptic Improves Quality of Life for Moderate PMD High Astigmat

By Dr. Ian Whipple, OD, VISION SOURCE, FARR WEST, UT

INTRODUCTION/HISTORY

46 YO Hispanic, highly astigmatic male presents with moderate Pellucid Marginal Degeneration OD and best corrected spectacle visual acuity of 20/100 OD. His OS shows no topographic changes and is easily correctable to 20/20. His current spectacle RX is OD Plano -6.50 x 045 to 20/100, OS +0.50 -0.75 x 123 to 20/20. He was previously fit in our office with a Onefit™ Sym-Toric scleral lens (OD). He was 20/25 with his lens but reported heavy fluctuations in vision, likely due to rotation, and intermittent foreign body awareness. This year, the patient simply asked if we could improve lens comfort and quality of his OD vision.

CURRENT OD LENS:

Onefit™, base curve 8.20, diameter 15.2, power +0.50 -1.50 x 117
(Onefit™ Sym-Toric), spherical haptic Landing Zone, standard Limbal Zone value, distance visual acuity of 20/25. No compromises were noted to the cornea, limbus, or sclera, other than subjective occasional foreign body awareness.

PLAN/GOAL:

Refit the patient into a larger diameter lens, Onefit™ MED design, to create better alignment and stabilize the optics. Overall, a fit with more stability should improve quality and consistency of visual acuity.
