Central Corneal Thickness and Corneal Hysteresis Together with Corrected Intraocular Pressure in Normal Population [PDF]
Al-Azhar International Medical Journal, 2023 Background: Cornea is the transparent window on the front of the eye with a dome shape. The cornea forms the anterior part of the eye outer coat. This coat's primary function is to protect the intra ocular components.

Mathematical modeling of corneal hysteresis
Russian journal of biomechanics., 2023 Mathematical modeling of the deformation of the eyeball under the external pressure applied to the cornea in a bounded area and gradually increasing and then decreasing according to a given law is performed. This relationship corresponds to the change in applied pressure in the ocular response analyzer (ORA) used in clinic.

Comment on ‘Corneal hysteresis in patients with dry eye’ [PDF]
Eye, 2012 Sir, We read with interest Firat and Doganay's1 recent report on effects of dry eye on corneal biomechanics. We propose the authors missed the opportunity to review an interesting hypothesis because of inadequate study design and methodology. Whereas the report aimed to determine effects of dry eye, the disease classification and study enrolment ...

Sequence variation at ANAPC1 accounts for 24% of the variability in corneal endothelial cell density
Nature Communications, 2019 The corneal endothelium is crucial for proper vision. Here, Ivarsdottir et al. perform genome-wide association studies for various corneal endothelial cell measurements and find that an intergenic variant near ANAPC1 explains 24% of the variance of ...

Response of corneal hysteresis and central corneal thickness following clear corneal cataract surgery [PDF]
Acta Ophthalmologica, 2011 AbstractPurpose: To evaluate the effect of routine phacoemulsification in corneal viscoelastic properties determined by corneal hysteresis (CH) and central corneal thickness (CCT) and to explore the impact of phaco energy on the above parameters.Methods: Forty‐one eyes of 41 patients undergoing cataract surgery were enrolled in this prospective study.
