Our findings indicate that topographically normal fellow eyes in patients with very asymmetric keratoconus differ from the eyes of healthy individuals in terms of their corneal epithelial and pachymetry maps.

eyes.<\/jats:p>","DOI":"10.1155\/2016\/5697343","type":"journal-article","created":{"date-parts":[[2016,6,9]],"date-time":"2016-06-09T18:05:21Z","timestamp":1465495521000},"page":"1-6","source":"Crossref","is-referenced-by-count":31,"title":["Assessment
