ABSTRACT

Keratoconus is a bilateral chronic, asymmetric, progressive ectatic condition, in which the cornea assumes a conical shape that induces abnormalities such as high regular and irregular astigmatism and increased higher order aberrations (HOAs), with adverse effects on the visual quality of the patients concerned. It is well established that keratoconus appears in the adolescence and its progression is more acute up to the third decade of life. A recent study shows that the estimated prevalence of keratoconus was 265 cases per 100,000. This study also showed that the prevalence was higher in men than in women. Keratoconus provides a decrease of quality of life to the patients who suffer from it. Moreover, it has been reported that despite its low prevalence and that it unusually leads to blindness, its impact on the public health is much higher than expected.
