Clinical Comparison of Two Daily Disposable Toric Soft Contact Lenses

October 9, 2023 updated by: Alcon Research
The primary purpose of this study is to demonstrate noninferiority in the visual acuity at distance when wearing PRECISION1™ for Astigmatism (P1fA) soft contact lenses compared to another commercially available, soft toric contact lens, MyDay® toric (MDT).

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Study participants will wear each study lens type in 1 of 2 randomized, crossover sequences. Participants will be expected to attend 4 visits and wear study lenses for at least 10 hours per day. The total duration of an individual's participation in the study will be up to 28 days.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

  • Able to wear contact lenses within a range of sphere & cylinder power and axes.
  • Willing to NOT use rewetting/lubricating drops at any time during the study.
  • Other protocol-defined inclusion criteria may apply.

Key Exclusion Criteria:

  • Current or previous P1fA and MDT habitual lens wearers.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Least Squares Means Distance Visual Acuity With Study Lenses at Week 1
Time Frame: Day 8 of each study lens type worn during the corresponding crossover period
Distance visual acuity (VA) was assessed with study lenses in place. VA was collected for each eye separately using logarithmic of the Minimum Angle of Resolution (logMAR) charts. LogMAR typically ranges from -0.3 (20/10 vision on the Snellen chart) to 1 (20/200 vision). A logMAR acuity of 0.0 corresponds to 20/20 Snellen (normal distance visual acuity), with a negative value denoting better than 20/20 visual acuity.
Day 8 of each study lens type worn during the corresponding crossover period
