Central and peripheral corneal sagittal height in keratoconus and healthy eyes

Keratoconus is a chronic, bilateral and asymmetric ocular condition characterized by a progressive thinning of the stroma and an increase in the curvature of the anterior and posterior surface of the cornea [1,2]. These morphological changes are often accompanied by increased high and low-order optical aberrations [3] and a consequent loss of vision, with a negative impact on the quality of life of patients [4]. Keratoconus is the most common primary corneal ectasia, presenting an estimated global prevalence of 1.38 cases per 1000 [5], with a similar occurrence irrespective of sex [6] and ethnicity.
