Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Keratitis healing within 15 days after the beginning of the treatment	Keratitis observed under slit lamp using fluorescein instillation. Keratitis considered healed if epithelialization of more than 50% and/or Oxford < grade 2	15 days
Secondary	Stable or decreased score for inflammatory and clinical signs of the ocular surface	Composite score for inflammatory and clinical signs of the ocular surface on 66 points. Duration and intensity are evaluated for secretion, dry eyes, tearing, foreign body sensation, fluctuating vision, photophobia, burning sensation and lids edema. Duration is evaluated from a scale from 0: never to 4: all the time. Intensity is evaluated from a scale from 0: slight to 2: severe. Localization and intensity are evaluated for conjunctival edema, conjunctival redness and neovascularization. Localization is evaluated on a scale from 0: no reaction to 4: reaction present in the whole eye.	1 day, 3 days, 5 days, 7 days, 10 days, 15 days, 30 days, 45 days
Secondary	Stabilisation or decrease of pain evaluated on visual analog scale	Visual Analog Scale (VAS) on 10 points from 0: no pain to 10: worst imaginable pain	1 day, 3 days, 5 days, 7 days, 10 days, 15 days, 30 days, 45 days
Secondary	Preservation of epithelialization	Preservation of new epithelialization evaluated under slit lamp using fluorescein instillation and Oxford grading system	15 days, 30 days, 45 days
Secondary	Change in eye dryness	Eye dryness evaluated by the Ocular Surface Disease Index (OSDI) (0-12 = normal; 13-22 = mild dry eye; 23-32 = moderate dry eye; >33 = severe dry eye)	15 days, 30 days, 45 days
