Conflicting results among studies might be due to inadequate number of eyes within the different stages of keratoconus, differences in exclusion criteria (current or previous contact lens wear), measurement devices (slit scanning or laser scanning confocal microscopy), techniques for image acquisition and cell density calculation (image size, image location, automated or manual cell counting), and classification of disease severity (Krumleich-Amsler, CLEK, etc).
Los lentes de contacto se utilizan en 90% de los casos de queratocono, ya sean blandos o rigidos y permeables a los gases; segun el CLEK (13) estos ultimos se emplean en 65% de los casos y con ellos se logra en 95% de los pacientes una agudeza visual de 20/40 o mejor.
