PURPOSE: The "Rose K Lens for Keratoconus" is a proprietary rigid contact lens design that has been reported and marketed as a lens that provides better visual acuity and comfort than other rigid contact lens designs for @entity9042 . METHODS: Twenty @entity1 with @entity9042 who were wearing rigid contact lenses were refitted into the Rose K lenses. Visual acuity measurements were taken with habitual lenses at the baseline visit and with the Rose K lenses at the completion of the study. Questionnaires were used to assess vision-specific quality of life, contact lens comfort, and self-reported assessment of vision. RESULTS: There were no statistically significant changes in high- or low-contrast visual acuity with the Rose K lenses. There was statistically significant improvement in self-reported assessment of vision and self-reported assessment of comfort in the eyes with more advanced @entity9042 . At the conclusion of the study, 72% of @entity1 preferred the Rose K lenses over their habitual lenses, and 87% reported that they would continue wearing the Rose K lenses. CONCLUSIONS: There was no difference in the visual acuity with the Rose K lenses compared with the @entity1 ' habitual lenses. Subjective assessment of vision and comfort indicate a statistical improvement for more advanced @entity9042 with the Rose K lens. We could not rule out a placebo effect as a source of subjective improvement in vision and comfort. Nevertheless, the successful fit rate and @entity1 preference demonstrate the usefulness of the Rose K lens in clinical practice.
