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

open access: yesPLoS 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 [PDF]

open access: yesJournal 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

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

open access: yesPLoS 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.

Comparison of corneal flap thickness using a FS200 femtosecond laser and a moria SBK microkeratome [PDF]

open access: yesInternational Journal of Ophthalmology, 2014
AIM: To evaluate differences in flap thickness resulting from use of an Alcon Wavelight FS200 femtosecond laser and a MORIA SBK microkeratome when making a 110-μm-thick corneal flap and to identify the potential factors that affect corneal flap thickness.
