Design outcomes

Primary

MeasureTime frame
To evaluate the safety of ex-vivo cultivated allogeneic limbal stromal stem cells for the treatment of visually significant superficial corneal stromal scarring and other pathologies including any ocular or systemic adverse effects at the various post-operative time points.Timepoint: Day 1, Day 7, Day 30, Day 90, Day 180 and Day 360 and 720

Secondary

MeasureTime frame
The secondary outcome measures are visual improvement and change in the density and appearance of the corneal scarring and other pathologies after treatment.Timepoint: Day 1, Day 7, Day 30, Day 90, Day 180 and Day 360 and 720
