Changes of Corneal Aberrations in Sitting and Supine Positions (Articolo in inglese)

The Keratron topographer, improved to measure patients in the supine position, was used to measure the corneal aberrations and the curvature in nine healthy volunteers. The first measurement took place with the subject in the sitting position and the others in the supine position, immediately after assuming the supine position and then 30 minutes later.
