Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: SygeLIX-Coll-T
Extract of umbilical cord lining constituted of Wharton's jelly put in suspension in microvials. Instillation by the patient in the sick eye of 1 drop 5 times a days (morning, noon, afternoon, evening and bedtime) for 40 days.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Absence of aggravated inflammatory signs, worsening of visual acuity or other side effect
Time Frame: Through study completion - average of 40 days
Inflammatory signs evaluated using a composite score 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
Through study completion - average of 40 days

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Re-epithelialization of the cornea
Time Frame: 7 days, 15 days, 40 days
Epithelialization assessed by the Oxford score after fluorescein instillation in the eye (0: no corneal staining to 5: severe corneal staining)
7 days, 15 days, 40 days
Improvement of dry eyes signs and symptoms
Time Frame: 7 days, 15 days, 40 days
Severity of dry eye evaluated using Ocular Surface Disease Index (OSDI) questionnaire
7 days, 15 days, 40 days
Improvement of visual acuity
Time Frame: 7 days, 15 days, 40 days
Visual acuity evaluated on Monoyer chart
7 days, 15 days, 40 days
