Is there a better "comfort drop"?

B E Caffery, J E Josephson

    Journal of the American Optometric Association

    Summary
    This summary is machine-generated.

    Patients wearing hydrogel contact lenses preferred preservative-free eye drops to alleviate dryness symptoms. Individual responses varied, but the group favored non-preserved formulations for comfort and relief.

    Area of Science:

    • Ophthalmology
    • Optometry
    • Contact Lens Technology

    Background:

    • Hydrogel contact lenses are widely used but can cause ocular dryness.
    • Dry eye symptoms are a common complaint among contact lens wearers.
    • Existing artificial tears often contain preservatives that may cause irritation.

    Purpose of the Study:

    • To compare the efficacy of 10 different eye drops in alleviating dryness symptoms in hydrogel contact lens wearers.
    • To determine patient preference for preserved versus non-preserved eye drops.
    • To identify optimal formulations for managing contact lens-related dry eye.

    Main Methods:

    • A randomized, double-blind study involving 45 participants with healthy eyes experiencing dryness during lens wear.
    • Participants evaluated 10 different eye drop formulations.

  • Patient-reported outcomes and preferences were collected.

    • Main Results:

    • Significant individual variability in response to different eye drops was observed.
    • As a group, participants demonstrated a preference for non-preserved eye drops.
    • Non-preserved formulations were favored for reducing dryness symptoms.

    Conclusions:

    • Preservative-free eye drops are preferred by hydrogel contact lens wearers experiencing dryness.
    • Formulation choice significantly impacts patient comfort and symptom relief.
    • Further research into preservative-free artificial tears for contact lens wearers is warranted.
