The process flow is defined as following: (1) the file study: which start by receiving the file of the patient, the file will be forwarded to appointed physicians coordinators for review and submission of medical report, then the medical report will be evaluated within the cell therapy committee and the patient will be asked for clinical examination, and after consultation a reply to the patient with medical decision will follow with an approval or not to be recruited and if yes, a brief report about the procedure will be submitted and explained in details to the patient, a consent form must be signed if the patient agree to be included in the study, (2) the patient admission: which may start by completion of the procedure forms and doing the pre-op evaluation (initial work up defined as a clinical and biological assessment upon C.A.S which may include unaided and best spectacle corrected visual acuity, refraction, slit lamp examination, intraocular pressure, fundoscopy, corneal topography, aberrometry, endothelial cell count (specular microscopy) as well as blood tests) by an ophthalmologist, followed by lipoaspiration of the subcutaneous adipose tissue to be performed by a plastic surgeon, then sample processing at a cGMP facility for isolation and characterization of the stromal vascular fraction enriched with ADAS as well as laminas preparing (the quality control assessment will be realized before and after all the steps of the procedure starting from the ADAS collection to transplantation including cell culture, cell quiescence, decellularization of human corneal lamina, recellularization of the laminas with ADAS, and transplantation; the assessment will include cell viability, cell number, cell apoptosis, immunophenotyping, infection, inflammation by analyzing the secreted cytokines from ADAS, lamina cutting, lamina thickness, immunostaining, confocal microscopy, etc.); (3) the delivery (transplantation) which starts by a peribulbar or retrobulbar anesthesia where the patient is placed under operating microscope, followed by a femtosecond laser assisted mid-stromal lamellar dissection, then the ADAS or laminas or recellularized laminas will be placed within the pocket, and finally closed by a superior incision closure. The patient will be putted under antibiotic/steroids for a defined period and followed by the team at 1 week, 2 weeks, 1 month, 3 months, 6 months and 1 year.
