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 ...

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).

The relationship between central corneal thickness and corneal curvature in adult Nigerians
Purpose: The aim of this study was to provide average values for central corneal thickness (CCT) and corneal curvature (CC) and also to determine a regression model for the relationship between CCT and CC in adult Nigerians without glaucoma. Methods: A
