Inclusion criteria

  • Healthy male and female.
  • Age ≥ 18 years old at screening visit.

Exclusion criteria

Exclusion Criteria:

  • Any ocular or systemic condition.
  • Patient with one blind eye.
  • Visual acuity of 20/40 in any eye.
  • Use of ocular or systemics medications.
  • or sensitivity to any component of the study treatments.
  • Contact lens users.
  • Ocular surgery within the past 3 months..
  • Women who were not using an effective means of or who were pregnant or nursing.
  • Participation in any studies of drugs within 90 days previous to the inclusion.
Terms in these criteria, in plain language(3)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Contraindication

A reason a treatment, test or procedure should not be given to a particular person, such as an allergy, another illness or a medicine they take.

Contraception

Ways of preventing pregnancy. “Highly effective” methods fail less than 1% of the time a year when used correctly — for example an IUD or an implant.

Criteria usually say which methods count and how long to keep using them after the last dose, sometimes for male participants too. Some studies accept a partner’s vasectomy if it was confirmed successful and that person is the participant’s only sexual partner.

Investigational drug or device

A drug or device being studied in a clinical trial.

It may be new, or already approved and being studied for another use, dose or form. Criteria often leave out people who took part in another study of one within a recent period, commonly 30 days or five half-lives.

What researchers measure

Primary outcomes

  1. Conjunctival bulbar hyperemia

    Conjunctival hyperemia is defined as the simplest reaction of the conjunctiva to a stimulus, a red appearance secondary to the vasodilation of the conjunctival vessels of variable intensity. He will graduate using the Efron scale. 0 Normal , 1 Very slight, 2 Mild, 3 Moderate, 4 Severe.

    Time frame: 10 days

  2. Number of Participants with adverse events

    he evaluation of adverse events requires a questioning conducted by the principal investigator and the appropriate exploratory techniques for its detection. the number of adverse events per study group will be considered for the analysis

    Time frame: 10 days

Secondary outcomes

  1. Intraocular pressure (IOP)

    Tonometry is the objective measure of Intraocular pressure, based primarily on the force required to flatten the cornea, or the degree of corneal indentation produced by a fixed force. Goldman's tonometry is based on the Imbert-Fick principle. the result will be expressed in millimeters of mercury and the comparison between groups will be carried out.

    Time frame: 10 days

  2. Visual ability (VA)

    The VA will be evaluated basally, without refractive correction with the Snellen chart. Which will be located in a place with adequate lighting, natural or artificial and at a distance of 3 meters from the subject to be evaluated

    Time frame: 10 days

  3. Eye comfort index (ICO)

    It is a questionnaire designed to measure the irritation of the ocular surface with Rasch analysis to produce estimates on a linear scale of intervals (ratings: 0-100). Similar to the index for ocular surface diseases, the ocular comfort index (ICO) evaluates symptoms. The ICO contains 6 items that focus on the discomfort associated with the ocular surface. Each of these questions has two parts, which inquire separately the frequency and severity of the symptoms. The evaluator will deliver the questionnaire to the subject and allow the subject to answer it calmly without any pressure and / or coercion, will only assist him if he has difficulty understanding any of the questions.

    Time frame: 10 days
