Acellular porcine corneal stroma (APCS) calcification occurs in the superficial corneal stroma about 1 month after LKP. The application of AS-OCT, von Kossa staining and SEM/EDS provides a basis for the clinical and pathological diagnosis of corneal calcification. The associated risk factors were mainly high phosphorus content and downregulated calcium metabolism-related proteins in APCS. Postoperative epithelial defects, inflammation and use of phosphorous eyedrops may promote corneal calcification.
