Inclusion criteria were a clinical diagnosis of ectasia in one eye and normal topometric and tomographic findings in the fellow eye (subclinical keratoconus), including a Belin\/Ambr\u00f3sio Enhanced Ectasia total deviation index from the Pentacam with less than 1.6 standard deviations from normative values and a Corvis Biomechanical Index score of greater than 0.5 in both eyes.<\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>RESULTS:<\/jats:title>\n            <jats:p>Tomographic and topographic analysis was normal in one eye and abnormal in the fellow eye in 12 patients. The biomechanical results with the Corvis Biomechanical Index were shown to be abnormal in both eyes of all patients and aided the diagnosis.<\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>CONCLUSIONS:<\/jats:title>\n            <jats:p>Biomechanical analysis showed abnormalities, whereas tomography and topography were normal.
