Influence of Dry Eye Disease on the Measurement Repeatability of Corneal Curvature Radius and Axial Length in Patients with Cataract. [PDF]

open access: goldJ Clin Med, 2022
The influence of dry eye disease (DED) on ocular biometric measurements is unclear. We aimed to investigate the effect of DED on the repeatability of ocular biometric measurements in cataract patients.

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

open access: yesTransl 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 ...

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

open access: goldNature 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 ...
