Study population: Data derived from subject who undergone surgical procedures involving de-epithelialization, which included CXL, PRK, and PTK, as well as those with a first diagnosis of corneal abrasionand treated with the ophthalmic solution containing CX-CMC and SP and with lubricant eye drops will be collected and analysed.

Brief summary: Data analyses and revision of the corneal re-epithelization in patients who underwent either PRK (Photorefractive Keratectomy), CXL (Corneal Cross-Linking), PTK (phototherapeutic keratectomy), or experienced a corneal abrasion. A novel ophthalmic solution containing cross-linked CMC (CX-CMC) and Silk Proteins (SP) has been made available on the market. Both molecules have been widely studied for their wound healing properties in the ophtalmic field. This new ophthalmic solution is the first on the market formulated with a CX-CMC and SP.
