About this study

Official title: Clinical Evaluation of Biomedics Monthly Toric and Avaira Vitality Toric

The aim of this study is to compare the short-term clinical performance of two toric contact lenses.

Read the detailed description

The aim of this study is to evaluate the short-term clinical performance of two toric contact lenses when compared to each other after 15 minutes of daily wear each.

Conditions
Astigmatism
Being tested
Lens A (ocufilcon D), Lens B (fanfilcon A)
Medical subject headings
Astigmatism

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Lens A (ocufilcon D)Device

    15 minutes of daily wear

  • Lens B (fanfilcon A)Device

    15 minutes of daily wear

Study groups in NCT06490302
Study groupRoleWhat they receive
Lens A (ocufilcon D)ExperimentalAll participants will wear lens A for 15 minutes (Period 1).
Receives: Device: Lens A (ocufilcon D)
Lens B (fanfilcon A)ExperimentalAll participants will wear lens B for 15 minutes (Period 2).
Receives: Device: Lens B (fanfilcon A)

What is being measured

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

  1. Overall Fit Acceptance

    Overall lens fit acceptance was measured on a scale from 0-4 (0= Should not be worn, 4= Perfect)

    Measured: At the end of 15 minutes of daily wear

Where is the study taking place?

The record lists 1 site in Mexico. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Overall Fit Acceptance (time frame: At the end of 15 minutes of daily wear). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 22 Aug 2025.
