Correlation of corneal epithelial thickness with clinical severity of dry eye

African Vision and Eye Health, 2023
Background: Spectral-domain optical coherence tomography (OCT) has been used to measure corneal epithelium thickness in dry eye disease, allowing assessment of ocular-surface damage in different disease severity.

Corneal Flap Thickness During Laser In Situ Keratomileusis

Kaohsiung Journal of Medical Sciences, 2007
To analyze the actual corneal flap thickness (FT) after flap making by MK-2000 microkeratome during laser in situ keratomileusis (LASIK), 42 females and 20 males with myopia or myopic astigmatism were enrolled in this study.

Association of Birth Weight with Central and Peripheral Corneal Thickness in Adulthood—Results from the Population-Based German Gutenberg Health Study

Children, 2021
Purpose: Low birth weight (BW) is associated with altered ocular geometry such as a steeper corneal shape in adulthood. However, it is unclear whether low birth weight affects corneal thickness development in the center or periphery in adulthood which ...

Early influence of endotamponade on corneal biomechanical parameters, central corneal thickness and accuracy of intraocular pressure measurement

Scientific Reports, 2023
To define the influence of air, SF6 gas and silicon oil 1000cs tamponade injection and oil tamponade removal on corneal biomechanics, central corneal thickness and intraocular pressure. 77 eyes referred to vitrectomy were divided into 4 groups: 19 to air
