However, quality assurance in retrieving and cultivating the tissue transplants is confined to visual and microbiological testing. To identify previous refractive surgery or morphological alterations, an automatic, noncontact, sterile screening procedure is required. Twenty-three corneal grafts have been measured in organ culture with a clinical spectral-domain optical coherence tomographer. Employing a biconic surface fit with 10 degrees of freedom, the radii of curvature and conic constants could be estimated for the anterior and posterior corneal surfaces. Thereupon, central corneal thickness, refractive values, and astigmatism have been calculated. Clinical investigations are required to elaborate specific donor\u2013host matching in the future.<\/jats:p>","DOI":"10.1117\/1.jbo.22.1.016001","type":"journal-article","created":{"date-parts":[[2017,1,5]],"date-time":"2017-01-05T09:34:56Z","timestamp":1483608896000},"page":"1-10","source":"Crossref","is-referenced-by-count":26,"title":["Optical
