Corneal Biomechanics in Glaucoma.

Klinische Monatsblatter fur Augenheilkunde, 2022
Now that is possible to measure the biomechanical parameters of the cornea in vivo, scientific and clinical interest has increased in changes in these parameters in glaucoma. These parameters may act as biomarkers for early diagnosis, but also serve to emphasize the increased vulnerability to intraocular pressure, reduced blood flow or changing ocular ...

Numerical modelling of corneal biomechanical behaviour

Computer Methods in Biomechanics and Biomedical Engineering, 2007
Numerical modelling based on finite element analysis is used to represent the biomechanical behaviour of the cornea. The construction details of the model including the discretisation method, the mesh density, the thickness distribution, the topography idealisation, the boundary conditions and the material properties, are optimised to improve ...

Concepts and misconceptions in corneal biomechanics

Journal of Cataract and Refractive Surgery, 2014
This review looks at biomechanical concepts and misconceptions related to in vivo assessment of corneal biomechanical response via air-puff deformation, including both human donor corneas and the translation of similar concepts to clinical studies.

Biomechanical Modeling of Refractive Corneal Surgery

Journal of Biomechanical Engineering, 2005
The aim of refractive corneal surgery is to modify the curvature of the cornea to improve its dioptric properties. With that goal, the surgeon has to define the appropriate values of the surgical parameters in order to get the best clinical results, i.e., laser and geometric parameters such as depth and location of the incision, for each specific ...

Influence of Pterygium on Corneal Biomechanical Properties

Current Eye Research, 2015
To evaluate the influence of pterygium on corneal biomechanical properties as measured by the ocular response analyzer (ORA).ORA measurements of 48 eyes with primary nasal pterygium were compared with those of healthy fellow eyes. The mean age of the patients was 46.6 ± 18.9 years.

Corneal biomechanical properties of patients with acromegaly

British Journal of Ophthalmology, 2014
Growth hormone (GH) and insulin-like growth factor-1 (IGF-1) excess in acromegaly have various effects on many organs. The ophthalmologic effects of GH and IGF-1 excess have not yet been investigated in detail. The aim of the current study is to compare the corneal biomechanical properties of patients with acromegaly and those of healthy subjects.45 ...

Corneal Biomechanical Properties in Rheumatoid Arthritis

Eye & Contact Lens: Science & Clinical Practice, 2015
To investigate the variations in biomechanical properties of the cornea in rheumatoid arthritis (RA) patients.A total of 53 RA patients, and 25 healthy individuals (control group) were enrolled. Rheumatoid arthritis patients were classified as in active phase (group 1; n=24) or in remission phase (group 2; n=29).
