About this study

This study will determine how multifocal contact lens correction affects symptoms of discomfort and asthenopia in a group of myopic contact lens wearers in the non-presbyopic age range (ages 30-40 years).

Read the detailed description

The purpose of this study is to determine how multifocal contact lenses affect contact lens comfort in non-presbyopic contact lens wearers. Current soft contact lens wearers who have symptoms of discomfort in their contact lenses will be recruited. Each subject (n = 84) will wear a single vision soft contact lens (Ultra single vision spherical lens) for two weeks and a low add power multifocal (Ultra for Presbyopia) for two weeks. Half of the subjects will wear the single vision lens first, and half of the subjects will wear the multifocal lens first. Initial lens group will be chosen randomly. Subjects will complete surveys that assess their vision and comfort which each lens, and ocular surface and accommodative/binocular vision status will be evaluated at the initial dispense and after wearing each lens for two weeks.

What participants receive

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

  • Multifocal Contact LensDevice

    The multifocal contact lens (Bausch + Lomb ULTRA® for Presbyopia) will be worn for two weeks

  • Single Vision Contact LensDevice

    The single vision contact lens (Bausch + Lomb ULTRA®) will be worn for two weeks

What is being measured

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

  1. Contact Lens Dry Eye Questionnaire-8 (CLDEQ-8) Score

    After wearing each lens type (single vision and multifocal) for 2 weeks, subjects will complete the CLDEQ-8, a survey that assesses symptoms of contact lens discomfort, to reports their symptoms of discomfort with each lens type. CLDEQ-8 scores with the multifocal will be compared to CLDEQ-8 scores of the single vision lens and the subjects' habitual contact lenses to determine if the multifocal improved comfort.

    Min-Max CLDEQ-8 range: 0-37 points Higher point values indicate more/worse symptoms

    Measured: Baseline and after 2 weeks of contact lens wear with each study lens (single vision and multifocal)

Questions about this trial

What is this clinical trial studying?

A study testing Multifocal Contact Lens and Single Vision Contact Lens in people with Asthenopia, run by Ohio State University at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 9 inclusion and 0 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 15 Feb 2019. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. 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?

Yes. Results are posted in the registry (first posted 15 Feb 2019). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

Contact Lens Dry Eye Questionnaire-8 (CLDEQ-8) Score (time frame: Baseline and after 2 weeks of contact lens wear with each study lens (single vision and multifocal)). 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 15 Feb 2019; AzTrials last refreshed its copy on 27 Oct 2026.
