Autorefraction Versus Manifest Refraction in Patients With Keratoconus

Keratoconus is a progressive corneal disease in which thinning of the corneal stroma causes the cornea to develop a cone-shaped ectasia, which leads to progressive myopia, irregular astigmatism, and often loss of visual acuity.1,2 Therefore, correctly measuring refractive errors is of paramount importance to assess visual performance, disease progression, and the prescription of visual aids in keratoconus.
