Abstract: Results with the Rose K Lens for Keratoconus
In a study of 20 keratoconus patients, 72% preferred Rose K over their previous lenses and 87% reported wanting to continue wearing them. Statistically significant vision and comfort was found with Rose K compared to the previously worn lenses. Placebo effect could not be ruled out.
