Etymology

From Latin cornea tela (“horny tissue”), from cornu (“horn”).

noun

1. (anatomy) The transparent layer making up the outermost front part of the eye, covering the iris, pupil, and anterior chamber.
   Or instead of treating them with the developing solution, the corneæ may be removed to a warm, concentrated solution of tartaric acid and remain there at the temperature of an incubating stove until the gold is fully reduced. 1885, Arthur Bolles Lee, chapter XI, in The Microtomist’s Vade‐Mecum, P. Blakiston, Son & Co, page 93
   In the lateral view (fig. 26) the corneae seemed very flat, their convexity not exceeding that of the bulbi (cornea plana?); 1969, P. P. H. Alkemade, Dysgenesis Mesodermalis of the Iris and the Cornea: A Study of Rieger’s Syndrome and Peter’s Anomaly, page 119
   The corneae were swollen without major infiltrates similar to longstanding disciform edema. 1981, R. Sundmacher, D. Neumann-Haefelin, A. Mattes, K. Cantell, “Connatal Monosymptomatic Corneal Endotheliitis by Cytomegalovirus”, in Herpetic Eye Diseases, J.F. Bergmann Verlag, page 501
   It is well known that in clinical practice the corneae from eyes enucleated for malignant melanoma of posterior choroid are usually utilized for corneal grafting. This research refers to cases of posterior melanomas which extended anteriorly, in which the utilization of the corneae for grafting was doubtful. 1983, A. Loffredo, G. Cennamo, A. De Lellis, A.
