New biomechanical index may help detect keratoconus
More than 98% of cases were correctly classified as being healthy or keratoconic using the Corvis Biomechanical Index, a new tool to help diagnose keratoconus, a study found.The multicenter retrospective study included 329 patients from the Vincieye Clinic in Milan, Italy, and 329 patients from the Rio de Janeiro Corneal Tomography and Biomechanics Study Group in Rio de Janeiro, Brazil. Researchers used the Corvis ST tonometer (Oculus) to determine 16 dynamic corneal response parameters for each patient and evaluated the parameters with the Corvis Biomechanical Index (CBI) to separate healthy (Read more...)
