Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Main Objective: To establish the efficacy of topical amniotic membrane extract to treat symptoms of severe dry eye disease.; Secondary Objective: Determine product tolerance in the eye. Validate changes in tear osmolarimetry. Validate reduction of inflammatory response at the ocular surface. Compare results with autologous serum eyedrops. ; Primary end point(s): 1. Determine tear volume and clearance by Schirmer Test type I and FCT (Fluorescein Clearance test) according to Tseng technique (10, 20 and 30 minutes). 2. Determine tear stability by TBUT (tear break up time). 3. Ocular surface Impression cytology analysis: 3.1. goblet cells quantity. 3.2. HLA-DR expression. 3.3. MUC1 expression. ;Timepoint(s) of evaluation of this end point: 1,3 and 6 months | — |
Secondary
| Measure | Time frame |
|---|---|
| Secondary end point(s): 1. Tear osmolarity. 2. Symptoms subjective validation by OSDI questionnaire. 3. Product tolerance subjective validation by EVA (visual analogic scale). ;Timepoint(s) of evaluation of this end point: 1,3 and 6 months | — |
