  • Title: Corneal wavefront aberration measurements to detect keratoconus patients.
    Author: Gobbe M, Guillon M.
    Journal: Cont Lens Anterior Eye; 2005 Jun; 28(2):57-66. PubMed ID: 16318836.
    Abstract:
    Distortions of the cornea associated with keratoconus are the manifestations of increased level, compared to normal, of higher order aberrations. It is highly relevant to use corneal aberrations to describe the optical quality of the cornea. The aim of the current study was to develop a keratoconus detection scheme based on Zernike coefficients. The results showed that the best detector to differentiate between suspected keratoconus and normal corneas was vertical coma (Z(3)(-1)) (specificity 71.9%; sensitivity 89.3%). The results demonstrated an improved use of videokeratoscope as a diagnostic tool for keratoconus detection that can be used for all types of videokeratoscopes.
