Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

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.

Study Type

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

  • Adult

Accepts Healthy Volunteers

Yes

Description

Inclusion Criteria:

  • Adult patients aged 18-40 of any sex and any race.
  • Reports habitually using digital device usage (phone, Ipad, computer, social media, video streaming) for 8 hours or more per day 5 days per week with plans to continue the habit throughout the study.
  • Wearing contact lenses for at least 13 hours daily 5 days per week.
  • Spherical refractive error between -11.00 D and +6.00D with < -0.75 D of astigmatism.
  • Willing to comply with the protocol instructions.
  • Has read (or has had read to), understood, and signed an Informed Consent.
  • Willing to not use any artificial tears, rewetting drops or dry eye treatments during the study.

Exclusion Criteria:

  • Active ocular infection or ocular inflammatory disease.
  • Presbyopic or pre-presbyopic that have a measured add power for reading.
  • Current Total 30 contact lens wearer.
  • Anterior basement membrane dystrophy or history of recurrent erosion syndrome or topographical abnormalities that might indicate ectasia or other corneal degenerative conditions.
  • Current or previous diagnosis of dry eye disease; currently using a dry eye treatment including but not limited to artificial tears, rewetting drops or prescription treatments.
  • History of severe / serious ocular pathology or other medical conditions that could result in an inability to safely complete the study.
  • Participation by the patient in any other investigational study within the past 30 days.
  • Unlikely to comply with protocol instructions for any reason (confusion, substance abuse, etc.). The Principal Investigator or the Medical Monitor reserves the right to declare a patient ineligible based on medical evidence that indicates the patient is unsuitable for the study.
  • Inability to utilize Clear Care Cleaning solution.
  • Pregnancy

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
Likert question about comfort satisfaction while wearing Total 30 contact lenses on a typical day (> 13 hours of daily wear) after 1 month of wear and heavy digital device usage (>8 hours daily wear).
Time Frame: 1 month
Likert Questionaire: Strongly Disagree, Disagree, Neither Agree nor Disagree, Agree, Strongly Agree
1 month

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Likert responses to insertion comfort and overall vision, and heavy digital device use on a typical day after 1 month of wear.
Time Frame: 1 month
Likert Questionaire: Strongly Disagree, Disagree, Neither Agree nor Disagree, Agree, Strongly Agree
1 month
Results of subjective ratings of patients using Total 30 lenses and heavy digital device usage with VAS diary questionnaire.
Time Frame: 1 month
VAS diary: scale 0-100 (0=No Discomfort 100= Maximal Comfort)
1 month
Report on total daily wear time and digital device usage.
Time Frame: 1 month
Survey: Total number of hours
1 month

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
