History and Etymology for keratomileusis

probably borrowed from Spanish queratomileusis, from querato- kerato- + -mileusis, probably erroneously for Greek smīleúsis "carving," from smī́lē "knife, scalpel" (of uncertain origin) + -eusis, action-noun suffix of verbs ending in -euō, -euein

Note: The word was presumably coined by the pioneer of the surgical procedure, the Spanish-born ophthalmologist José Ignacio Barraquer Moner (1916-98); it occurs in his paper "Queratomileusis para la correción de la miopía," Archivos de la Sociedad Americana de Oftalmología y Optometría, vol. 5 (1964), pp. 27-48.
