Design outcomes
Primary
| Measure | Time frame |
|---|---|
| It is expected to find a reduction in the epithelial defect by measuring the diameters in millimeters in the slit lamp examination and by measuring the defect area in pixels in the photophotography using analysis software | — |
Secondary
| Measure | Time frame |
|---|---|
| Reduction of the presence of metalloproteinases on the ocular surface through qualitative testing ;Improvement in ocular symptoms through a reduction in total score of Ocular Surface Disease Index questionnaire;Improvement in break-up tear time through an increase in time measured in seconds ;Improvement in epithelial lesion pattern through reduction of score by the Oxford Score;Improvement in confocal microscopy aspects through inflammatory and nervous cells analysis ;Improvement in ocular surface parameters evaluated with Idra ® through comparisons between qualitative and quantitative parameters | — |
