About this study

Bilateral dispensing clinical trial of fanfilcon A toric lens verses enfilcon A toric lens over two weeks.

Read the detailed description

Evaluation of the clinical performance of an investigational silicone-hydrogel lens called fanfilcon A (test) compared to a FDA-cleared commercially available contact lens called enfilcon A toric lens (control) when worn on a daily wear basis over 2 weeks in a randomized, bilateral, cross-over, dispensing study.

Being tested
fanfilcon A, enfilcon A
Medical subject headings
Myopia, Hyperopia, Astigmatism

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Comfort (Subjective Rating Scale)

    Participant rating for comfort at dispense visit and at the 2 week follow-up on a subjective rating scale (0-100, 0=cannot be worn. Causes pain,100=Cannot be felt ever)

    Measured: Dispensing (Baseline) and 2 weeks

  2. Comfort Preference

    Subjective assessment for comfort preference for each lens pair. Choices: fanfilcon A lens, enfilcon A lens, No preference.

    Measured: Dispensing (Baseline) and 2 weeks
