Detailed Description

Number of patients: n = 24 12 subjects per group (both eyes). Main inclusion criteria: Clinically healthy subjects. Treatment duration: 7 days. Duration of subject in the study: 15 to 22 days. Adverse events will be reported and cataloged based on the MedDRA dictionary and will be reported to the corresponding regulatory entity. The sponsor will carry out monitoring or quality visits to the research sites where it corroborates the information of the source documents and will contrast them with the information presented in the electronic CRF. Electronic case report forms will be evaluated by the clinical research associate and the clinical team of the sponsor (medical ophthalmologist researcher and pharmacologist of clinical safety). Statistical methodology: The data will be expressed with measures of central tendency: mean and standard deviation for the quantitative variables. The qualitative variables will be presented in frequencies and percentages. The statistical analysis will be carried out by means of the Mann-Whitney U test for the quantitative variables for the difference between the groups. The difference between the qualitative variables will be analyzed by means of X2 (Chi2). An alpha ≤ 0.05 will be considered significant.

Clinical Trial Outcome Measures

Primary Measures

  • Number of Adverse Events
    • Time Frame: during the 14 days of evaluation, including the safety call (day 14)
    • primary security variable the adverse events will be evaluated with a scale of Present / Absent, it is a nominal variable, the normal value is absent. it will be evaluated by the number of reported cases per group.
  • Eye Comfort Index
    • Time Frame: will be evaluated at the end of the treatment, at the final visit (day 8)
    • 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).The Eye comfort index contains items that focus on the discomfort associated with alterations of the ocular surface. Values closer or equal to one hundred (100) correspond to greater discomfort, while values closer or equal to zero (0) correspond to greater comfort.

Secondary Measures

  • Number of Eyes With Epithelial Defects by Grade
    • Time Frame: will be evaluated at the end of the treatment, at the final visit (day 8)
    • The epithelial defects will be evaluated by means of two stains, green lissamine and fluorescein, it is a discrete variable that will be realized by direct observation, it will be staged according to the degrees of the oxford scale that go from 0 to 5 (0-V) according to its severity, where 0 is the normal lower limit and 5 the upper limit of defects.
  • Visual Ability
    • Time Frame: will be evaluated at the end of the treatment, at the final visit (day 8)
    • The visual capacity variable will be reported using as a unit of measure a fraction, this is taken from a visual test with the Snellen primer, it is a Nominal type variable. where the optimal vision is 20/20 or 1.0 in decimal and the worst 20/200 or 0.1 in decimal number. For the appropriate management of the data, the result of the fraction obtained from the snellen scale is transformed to decimals, in this case subjects close to or equal to 1.0 have better visual acuity while subjects close to or equal to 0.1 have worse visual acuity. The decimal equivalence scale is the result of the division of the fraction obtained in the Snellen chart. where 20/20 = 1.0; Do not confuse with Logmar scale where 20/20 = 0.0 Equivalences Snellen Scale = decimals: 20/200=0.1, 20/100=0.2, 20/50=0.4, 20/40=0.5, 20/30=0.66, 20/25=0.8, 20/20=1.0, etc.
  • Participants With Conjunctival Hyperemia (CH) by Grade
    • Time Frame: will be evaluated at the end of the treatment, at the final visit (day 8)
    • Conjunctival hyperemia will be evaluated as an ordinal variable, by direct observation and staged using the Efron scale as Normal / Very Light / Mild / Moderate / Severe. Based on this scale, the normal and mild stages are considered without pathologies or normal. Mild, moderate and severe are considered pathological.
  • Participants With Chemosis
    • Time Frame: will be evaluated at the end of the treatment, at the final visit (day 8)
    • The chemosis will be evaluated, as a nominal variable, by direct observation and it will be staged as present and absent, where the normality is that said variable is absent.
