About this study

To evaluate and compare the performance of two monthly replacement multifocal contact lenses in existing wearers.

Read the detailed description

This was a prospective, randomized, participant-masked, crossover, bilateral dispensing study. Each lens type was worn for approximately 4-6 weeks: the lens prescription of each lens type was optimized after 3-10 days wearing experience, prior to starting a 1-month (28-32 days) wear period.

What is being measured

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

  1. Lens Handling for Insertion

    Subjective rating collected in office using a 0-100 scale, where 0=Very difficult and 100=Very easy. The participant rated the study lens considering a typical day in the last 1 month of wear.

    Measured: 1 month
