Scaling and maintenance of corneal thickness during aging. [PDF]

PLoS ONE, 2017
Corneal thickness is tightly regulated by its boundary endothelial and epithelial layers. The regulated set-point of corneal thickness likely shows inter-individual variations, changes by age, and response to stress.

Central Corneal Thickness in Children [PDF]

Archives of Ophthalmology, 2011
To determine the central corneal thickness (CCT) in healthy white, African American, and Hispanic children from birth to 17 years of age and to determine whether CCT varies by age, race, or ethnicity.Prospective observational multicenter study. Central corneal thickness was measured with a handheld contact pachymeter.A total of 2079 children were ...

Comparison of corneal thickness in patients with dry eye disease using the Pentacam rotating Scheimpflug camera and anterior segment optical coherence tomography.

PLoS ONE, 2020
The purpose of this study was to compare central corneal thickness, thinnest corneal thickness, and the thinnest point of the cornea between Pentacam and anterior segment optical coherence tomography (ASOCT) in patients with dry eye disease (DED).

Posterior Corneal Surface Stability after Femtosecond Laser-Assisted Keratomileusis

Journal of Ophthalmology, 2015
The purpose of this study was to evaluate posterior corneal surface variation after femtosecond laser-assisted keratomileusis in patients with myopia and myopic astigmatism. Patients were evaluated by corneal tomography preoperatively and at 1, 6, and 12

Submicron Metasurface Reconfigured Multiband Smart Windows

Advanced Functional Materials, EarlyView.
This work presents a submicron metasurface reconfigured multiband thermochromic smart window. By integrating subwavelength nanostructures into a Fabry−Perot resonator configuration, it mitigates conventional trade‐offs to simultaneously deliver high luminous transmittance and robust solar heating and radiative cooling modulation capabilities ...
