Trial summary

This will be an up to six months, subject-masked, contralateral, parallel-group, randomised, daily wear study. All subjects will wear the Test lens in one eye and the Control lens in the other eye. Data from the first four weeks of Test and Control lens exposure will be used for the FDA 510 (k) submission. Read more about this study

About this study

Official title: Clinical Evaluation of Hydra-PEG (Polyethylene Glycol) Treatment (HPT) Treated Rigid Contact Lenses Made From Roflufocon D

This will be an up to six months, subject-masked, contralateral, parallel-group, randomised, daily wear study. All subjects will wear the Test lens in one eye and the Control lens in the other eye. Data from the first four weeks of Test and Control lens exposure will be used for the FDA 510 (k) submission.

What is being measured

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

  1. questionnaire addressing subjective comfort and wear time

    Subjects rated on a scale from 1 to 10, where 1 was 'poor' and 10 was 'excellent'.

    Measured: subjects will be followed-up for one month

  2. conjunctival redness - ocular biomicroscopy

    Graded based on a grading scale which ranged from 0 to 4, where 0 is none, 1 is trace, 2 is mild, 3 is moderate and 4 is severe.

    Measured: subjects will be followed-up for one month

  3. corneal staining - ocular biomicroscopy

    Graded based on a grading scale which ranged from 0 to 4, where 0 is none, 1 is trace, 2 is mild, 3 is moderate and 4 is severe.

    Measured: subjects will be followed-up for one month

Questions about this trial

What is this clinical trial studying?

A study testing roflufocon D contact lenses and RGP contact lenses made from roflufocon D in people with Ametropia, run by Contamac Ltd at 1 site in Germany.

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

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?

questionnaire addressing subjective comfort and wear time (time frame: subjects will be followed-up for one month). The study lists 3 primary outcomes in all. 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?
