Keratoconus cone location influences ocular biomechanical parameters measured by the Ocular Response Analyzer [PDF]
Eye and VisionBackground Keratoconus is characterized by asymmetry in the biomechanical properties of the cornea, with focal weakness in the area of cone formation. We tested the hypothesis that centrally-measured biomechanical parameters differ between corneas with ...
