Experimental Assessment of Human Corneal Hysteresis

Current Eye Research, 2008
Hysteresis is a viscoelastic property characterized by the difference in behavior under loading and unloading. The aim of the study was to determine corneal hysteresis using experimental means.Twenty-nine human corneas with 50-95 year age were subjected to cycles of pressure loading and unloading.

Central Corneal Thickness and Corneal Hysteresis Associated With Glaucoma Damage

American Journal of Ophthalmology, 2006
We sought to measure the impact of central corneal thickness (CCT), a possible risk factor for glaucoma damage, and corneal hysteresis, a proposed measure of corneal resistance to deformation, on various indicators of glaucoma damage.Observational study.Adult patients of the Wilmer Glaucoma Service underwent measurement of hysteresis on the Reichert ...

Corneal hysteresis and glaucoma

International Ophthalmology, 2018
To review and summarize the characteristics of corneal hysteresis (CH) and its relationship with glaucoma.A PubMed search was carried out using the terms "corneal hysteresis", "glaucoma", and "biomechanics". Up to March 2018, all studies published in English are included in this review.The value of CH reflects the ability of corneal tissue to absorb ...

Factors affecting corneal hysteresis in normal eyes

Graefe's Archive for Clinical and Experimental Ophthalmology, 2008
To evaluate factors affecting corneal hysteresis (CH) in normal eyes.We examined 86 normal eyes of 43 healthy volunteers (age, 39.1 +/- 14.5 years (mean +/- standard deviation); range, 19 to 68 years; gender, 26 men, 60 women; manifest refraction, -2.25 +/- 2.89 diopters (D); range, -9.13 to 3.88 D).

Corneal hysteresis following descemetorhexis with endokeratoplasty

Annals of Ophthalmology, 2007
The corneal biomechanical properties following descemetorhexis with endokeratoplasty (DXEK) and in normal subjects were studied in 100 eyes (12 DXEK and 88 age-matched normal subjects). Corneal hysteresis measurements were significantly lower in DXEK vs normal subjects. DXEK has a direct effect on corneal hysteresis and corneal biomechanical properties
