What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Ocular Comfort Index	Ocular Comfort Index (OCI) Questionnaire for evaluation of dry eye symptoms in a scale from 0 to 100. Greater scores mean a worse outcome.	Day 8
Incidence of Related Unexpected Adverse Events (AE)	Presence/absence of related non expected adverse events	Day 10

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Changes in Best Corrected Visual Acuity (BCVA)	Visual acuity (VA) is a test of visual function. It will be evaluated with the Snellen chart. The Snellen chart is the standard tool used to evaluate visual acuity. It was located in a place with adequate lighting, natural or artificial and at a distance of 3 meters from the subject to be evaluated. The contralateral eye to which it will be evaluated is covered, then the examiner detects until the line can clearly see the letters given he or she a score, the normal score for a VA is 20/20.This score can be expressed in fraction (i.e. 20/20) decimal (i.e. 1.0), or LogMAR (i.e. 0) formats. In this study, VA is expressed in decimal format. In decimal format, a lower number is a worse outcome.	Baseline vs Day 8
Conjunctival and Corneal Staining With Lissamine Green	Conjunctival and corneal staining with lissamine green. The evaluation will take place after applying the lissamine green stain on the ocular surface and evaluating the resulting staining pattern. This will be measured through the Oxford scale which includes 6 grades: Absent (0), Minimal (I), Mild (II), Moderate (III), Marked (IV), Severe (V).	Day 8
Conjunctival and Corneal Staining With Fluorescein	Conjunctival and corneal staining with fluorescein. The evaluation will take place after applying the fluorescein tain on the ocular surface and evaluating the resulting staining pattern. This will be measured through the Oxford scale which includes 6 grades: Absent (0), Minimal (I), Mild (II), Moderate (III), Marked (IV), Severe (V).	Day 8
Conjunctival Hyperemia	Rate of conjunctival hyperemia will be evaluated through the Efron scale which includes 5 grades: Normal (0), Very Mild (I), Mild (II), Moderate (3), and Severe (4).	Day 8
Chemosis Incidence	Chemosis incidence will be evaluated at the end of the treatment at the final visit	Day 8
