Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
* not invasiveness to the patient, who could in time not like the repeated withdrawals
* applicability even in patients with underlying systemic conditions. They may contain in their blood, among others, higher levels of pro-inflammatory factors, with the consequence of poor and inappropriate final product to be prepared and delivered to the eye
* reliability, since the homologous products can be prepared, controlled, also validated under the microbiological profile and standardized advance, then kept frozen until the dispensation
* conceptually unlimited availability of the product to be dispensed
* versatility of therapeutic indications, based on different GF levels which are estimated in advance
The purpose of this study is to evaluate the effect of two products derived from two different blood sources (cord blood collected at birth from placenta umbilical veins and adult subject donor peripheral blood) in the treatment of severe keratopathies.

Study Design
Understand how the trial is structured, including allocation methods, masking strategies, primary purpose, and other design elements.
RANDOMIZED
PARALLEL
The study consists of two phases: Phase 1 is runned for one month treatment. The assignment of the treatment in Phase 1 is performed through a computer based randomization process, blind to the patient and the clinician, only known to the Transfusion Service personnel. The patient enter Phase 2 only in case of a corneal epithelial damage relapse taking place within two months after the end of Phase 1, and the treatment assigned belongs to the remaining arm. In this case also, the treatment is only known to the Transfusion Service personnel, trained to keep data aside.

CBS eyedrops
Eyedrops prepared from CBS (Cord Blood Serum), and administered 1 drop/each eye/8 times per day, for 30 days
PBS eyedrops
PBS eyedrops (prepared from adult peripheral blood serum) will be provided as frozen vials containing 0.8 ml of the product and will be administered at a regimen of 1 drop / 8 times day / each eye during the waking period, with the last administration to take before bedtime.
PBS eyedrops
Eyedrops prepared from PBS (Peripheral Blood Serum) from adult donor subjects, administered 1 drop/each eye/8 times per day, for 30 days
CBS eyedrops
CBS eyedrops (prepared from umbilical cord blood serum) will be provided as frozen vials containing 0.8 ml of the product and will be administered at a regimen of 1 drop / 8 times day / each eye during the waking period, with the last administration to take before bedtime.
