Evaluation of Perfluorohexyloctane Eyedrops in Habitual Contact Lens Wearers.

Background: Dry eye disease is one of the most common disorders we see in practice today. Perfluorohexyloctane (PFHO) ophthalmic solution (MIEBO®) (©Bausch + Lomb) is a novel, non-aqueous, single entity, preservative-free ophthalmic drop recently approved by the FDA for treatment of the signs and symptoms of dry eye disease.

Purpose: While the safety and efficacy of PFHO has been demonstrated in non-contact lens wearers, its safety and potential benefits in habitual contact lens wearers have not been explored. This report presents the results of a trial designed to evaluate the safety of PFHO and its effect on contact lens comfort, specifically in established contact lens wearers.

Patients And Methods: The study included 47 patients who were adjusted contact lens wearers with a best corrected visual acuity of 20/25 or better at distance. All the patients were healthy contact lens wearers with no dry eye symptoms.

Results: A significant improvement in comfort scoring was observed without any significant changes in osmolarity, meibography scores, and total fluorescein staining.

Conclusion: These findings suggest that PCHO is safe for contact lens wearers to use and shows promise to reduce contact lens dropout.
