Corneal biomechanics: a review [PDF]
Australasian journal of optometry, The, 2015 Biomechanics is often defined as 'mechanics applied to biology'. Due to the variety and complexity of the behaviour of biological structures and materials, biomechanics is better defined as the development, extension and application of mechanics for a better understanding of physiology and physiopathology and consequently for a better diagnosis and ...

Corneal Biomechanics and Biomaterials
Annual Review of Biomedical Engineering, 2011The ability to clearly observe one's environment in the visible spectrum provides a tremendous evolutionary advantage in most of the world's habitats. The complex optical processing system that has evolved in higher vertebrate animals gathers, focuses, detects, transduces, and interprets incoming visible light.

In vivo characterization of corneal biomechanics
Journal of Cataract and Refractive Surgery, 2014Interest in corneal biomechanics has increased with the development of new refractive surgery techniques aimed at modifying corneal properties and a variety of surgical options for corneal ectasia management. The human cornea behaves as soft biological material.

The alterations of corneal biomechanics in adult patients with corneal dystrophy
Eye, 2022To evaluate the changes of corneal biomechanics in granular, lattice and macular corneal dystrophy (GCD, LCD and MCD), and to assess the agreement of intraocular pressure (IOP) between Corvis ST tonometer (CST) and Goldmann applanation tonometer (GAT) and the agreement of central corneal thickness (CCT) between CST and ultrasound pachymeter (USP) in ...

Biomechanical Model of Corneal Transplantation
Journal of Refractive Surgery, 2006ABSTRACT PURPOSE: Refractive consequences of corneal transplants are analyzed using corneal biomechanical models assuming homogeneous and in homogeneous stiffness distributions across the cornea. Additionally, refractive effects of grafts combined with volume removal procedures are also evaluated to develop methods to reduce postoperative ...

The Effect of Smoking on Corneal Biomechanics
Current Eye Research, 2016To determine the effect of smoking on corneal biomechanical behavior.The medical records of consecutive patients that presented to the ophthalmology department were reviewed. History of smoking and ophthalmological examination findings were recorded. The smoking group met the following criteria: a clear history of and present smoking habit, negative ...

Changes of Corneal Biomechanics With Keratoconus
Cornea, 2012To perform advanced analysis of the corneal deformation response to air pressure in keratoconics compared with age- and sex-matched controls.The ocular response analyzer was used to measure the air pressure-corneal deformation relationship of 37 patients with keratoconus and 37 age (mean 36 ± 10 years)- and sex-matched controls with healthy corneas ...

Corneal biomechanics in different age groups
International Ophthalmology, 2020To report on the corneal biomechanical characteristics, namely the corneal hysteresis (CH), corneal resistance factor (CRF), as well as the intraocular pressure (IOP) goldman compensated (IOPg), and the cornea compensated (IOPcc), using the ocular response analyzer (ORA) in different age groups in a cohort of normal individuals from the second decade ...
