Examination: First of all, keratoconus is mostly a sporadic disease with an incidence of 1:2000. It is bilateral & not due to inflammatory conditions. Less frequently it's due to hereditary factors. Corneal topography is very helpful in diagnosing the condition, although other clinical signs are picked up during examination. Improving vision generally requires ridged contact lenses, although some néed surgery.
