Effect of central corneal curvature on corneal material stiffness parameter acquired by dynamic corneal responses [PDF]
The stress–strain index (SSI) is a measure of corneal material stiffness, which is obtained using the Corvis ST algorithm based on dynamic corneal response parameters. The reduced SSI corresponds to the longer axial length (AL).

Corneal Curvature: the Influence of Corneal Accommodation and Biomechanics on Corneal Shape. [PDF]
Variation in the presence and magnitude of corneal conformational changes during accommodation may predict postoperative ectasia following refractive surgery and assist in the early diagnosis of corneal ectatic disorders. The current study aimed to establish a baseline for corneal refractive changes during ocular accommodation and to clarify the role ...

Influence of corneal astigmatism, corneal curvature and meridional differences on corneal hysteresis and corneal resistance factor [PDF]
This study investigated the influence of corneal astigmatism, corneal curvature and meridional differences on corneal hysteresis (CH) and the corneal resistance factor (CRF) in a group of normal Chinese persons.Ninety-five participants were recruited and data from the eye with higher corneal astigmatism were analysed. The anterior corneal curvature was
