Clinical Trial Summary

This is a phase IV clinical study to demonstrate the non-inferiority of Manzanilla Sophia® compared to Meticel Ofteno® 0.5% in providing restful sensation to the eyes. This will be evaluated by measuring the incidence of unexpected adverse events related to the interventions, the incidence of conjunctival hyperemia and the incidence of sensation of comfort with the application, when applied by the Principal Investigator (PI).

Primary:

-Analog visual eyestrain test score

Secondary:

• Incidence of unexpected adverse events related to the interventions

• Incidence of conjunctival hyperemia

• Incidence of sensation of ocular dryness

• Incidence of ocular irritation

• Incidence of sensation of (sleep-crust)

• Incidence of sensation of comfort with the application, when applied by the Principal Investigator (PI)

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Analog visual eyestrain test score	The PI will evaluate the analog visual eyestrain test score by applying a direct questionnaire to the subject and allowing the subject to answer it calmly without any pressure.; The analog visual test score is a questionnaire designed to establish the degree of eyestrain (fatigue) according to its symptomatology. This questionnaire will be as follows for frequency: never (1), sometimes (2), 50% of the time (3), almost all the time (4) and all the time (5).	Days: 0 (Basal Visit) and 8 (Final Visit).
Secondary	Incidence of unexpected adverse events related to the interventions	Any unfavorable medical condition affecting the subject after the administration of the investigation product, related to such intervention.	Days 0 (Basal Visit), 3 (Visit 1), 8 (Final Visit) and 10 (Safety Call)
Secondary	Incidence of conjunctival hyperemia	Any signs of conjunctival hyperemia in between interventions.; Conjunctival hyperemia is defined as the red appearance secondary to vasodilatation of the conjunctival blood vessels of variable intensity.	Days 0 (Basal Visit), Days 3 (Visit 1) and 8 (Final Visit)
Secondary	Incidence of sensation of ocular dryness.	The subject will be questioned directly.; Ocular dryness is defined as the subjective sensation of dry eye.	Days 0 (Basal Visit), Days 3 (Visit 1) and 8 (Final Visit)
Secondary	Incidence of ocular irritation	The subject will be questioned directly.; Ocular irritation is defined as the subjective sensation of eye irritation.	Days 0 (Basal Visit), Days 3 (Visit 1) and 8 (Final Visit)
Secondary	Incidence of sensation of (sleep-crust)	The subject will be questioned directly.; Sleep crust is defined as the subjective sensation of the presence of eye discharge.	Days 0 (Basal Visit), Days 3 (Visit 1) and 8 (Final Visit)
Secondary	Incidence of sensation of comfort with the application, when applied by the Principal Investigator (PI)	The subject will be questioned directly by de PI during the final visit.	Day 8 (Final Visit)
