Inclusion Criteria: * Healthy male and female. * Age between 18 and 40 years old at screening visit. * Signed informed consent Exclusion Criteria: * Patient with one blind eye. * Any ocular or systemic condition. * Visual acuity of 20/100 in any eye. * Use of ocular or systemic medication. * Contraindications or sensitivity to any component of the study treatment. * Contact lens users. * Ocular surgery within the past 3 months.. * Pregnant, nursing or childbearing potential women who were not using effective contraception. * Participation in any studies of investigational drugs within 90 days previous to the inclusion.

Outcomes

Primary Outcomes

Visual Acuity (VA)

The VA will be evaluated basally, without refractive correction with the Snellen chart. A Snellen chart is placed at a standard distance: 20 ft. At this distance, the symbols on the line representing "normal" acuity subtend. This line, designated 20/20 is the smallest line that a person with normal acuity can read at a distance of 20fs. the scale consists of 11 lines of letters of different size, the size of the letter gives a fractional value according to the visual acuity of the patient, the value is inversely proportional to the visual acuity, if the denominator is greater the visual acuity will be less. Line 1: 20/200 Line 2: 20/100, Line 3: 20/70, line 4: 20/50, line 5: 20/40, Line 6: 20/30, line 7: 20/25, Line 8: 20/20, line 9: 20/15, line 10: 20/13, line 11: 20/10. the results will be expressed as the mean of the denominator of the Snellen scale (scale 20/--) example. 18.5 ± 1.5, that means the final result is 20/18.5 ± 1.5

Time frame: 11 days

Secondary Outcomes

Intraocular Pressure (IOP)

The tension of a healthy eye should be between 10 and 20 millimeters of mercury (mmHg). In Goldman-type Applying Tonometry, the cornea is flattened, and the intraocular pressure is determined by measuring the force of application and the flattened area.

Time frame: 11 days

Number of Eyes With Epithelial Defects

the number of epithelial defects was evaluated by the application of fluorescein, Staining was performed with fluorescein which stained the degenerated cells and the mucus filaments present in the tear film.

Time frame: 11 days

Number of Cases With Adverse Events

The presence of adverse events was evaluated by the number of cases.

Time frame: 11 days
