Corneal Curvature: the Influence of Corneal Accommodation and Biomechanics on Corneal Shape. [PDF]

open access: goldTransl Vis Sci Technol, 2019
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 ...

Correlation between Central Corneal Thickness, Corneal Curvature and Axial Length of The Eye in Myopic & Hypermetropic Patients [PDF]

open access: diamondSVU - International Journal of Medical Sciences, 2023
Background: The refractive errors are the most common cause of visual deterioration worldwide. Correction of refractive errors can be divided into optical & surgical methods with global tendency toward the surgical correction of refractive errors which ...

Effect of central corneal curvature on corneal material stiffness parameter acquired by dynamic corneal responses [PDF]

open access: yesFrontiers in Bioengineering and Biotechnology, 2023
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).

Regulation of corneal stromal cell behavior by modulating curvature using a hydraulically-controlled organ chip array

open access: greenNature Communications
Corneal curvature abnormalities drive ectatic diseases, yet their mechanobiological effects on stromal cells remain poorly understood. We developed a hydraulically controlled curvature array chip recapitulating disease-relevant geometries (33-56D) to ...

The relationship between central corneal thickness and corneal curvature in adult Nigerians

open access: goldAfrican Vision and Eye Health, 2011
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
