“…Amsler's 15 1938 report on 600 patients suggested that progression was asymmetric and variable, progressing rapidly during a period of 3 to 5 years and then slowing or stopping. In 1946, Amsler 16 reported follow-up data on 286 eyes followed for 3 to 8 years. Twenty-two percent of eyes demonstrated some progression.…”

“…In the AK system, the severity of keratoconus is graded from stages I-IV using spectacle refraction, central keratometry, presence or absence of scarring, and central corneal thickness. 20 The AK classification predated modern imaging technologies. Others have used this system with various modification and additions in an attempt to better diagnosis or characterize the severity of disease.…”

Several methods have been described to both evaluate and document progression in keratoconus and to show efficacy of cross-linking, however, there are no consistent generally accepted parameters. Modern corneal tomography, including both anterior and posterior elevation and pachymetric data can be used to screen for ectatic progression, be employed to detect earlier change and additionally to show efficacy of new treatment modalities, such as crosslinking.To describe specific quantitative values that can be used as progression and efficacy determinants, the normal noise measurements of the three parameters used in the ABCD keratoconus classification (corneal thickness at the thinnest point, anterior and posterior radius of curvature taken from the 3.0 mm optical zone centered on the thinnest point), were determined. Values were obtained from both a normal population and a known keratoconic population. The 80 and 95% one-sided confidence intervals for all three parameters were surprisingly small, suggesting that they may perform well as progression and efficacy determinants.

“…1 Amsler-Krumeich classification 7,8 and collaborative longitudinal evaluation of keratoconus (CLEK) 9 classifications are the most commonly used to classify the keratoconus severity. Amsler-Krumeich classification proposes four different levels using refractive, topographic and biomicroscopic corneal signs.…”
