Smoking and Corneal Biomechanics

Smoking and corneal biomechanics.

Dear Editor: Changes in the biomechanical properties of the human cornea play an important role in the pathogenesis of corneal dystrophies such as pellucid marginal corneal degeneration and keratoconus. The latter primarily affects young people and is a leading cause of severe visual impairment. Keratoconus is characterized by weakened corneal biomechanics that leads to progressive bulging and ...

Tobacco smoking and its impact on corneal biomechanics.

Corneal biomechanics - a review.

PURPOSE In recent years, the interest in corneal biomechanics has strongly increased. The material properties of the cornea determine its shape and therefore play an important role in corneal ectasia and related pathologies. This review addresses the molecular origin of biomechanical properties, models for their description, methods for their characterisation, techniques for their modification,...

Corneal biomechanics: Where are we?

Corneal biomechanics emerged as a very hot topic for research in Ophthalmology. In this issue, Sharifipour and coworkers present an observational cross-sectional study in healthy individuals that evaluated the correlations of corneal viscoelastic properties measured by the Ocular Response Analyzer (ORA, Reichert, Buffalo, NY) with central corneal thickness (CCT) in different age groups. In this...

Biomechanics of Corneal Ring Implants

PURPOSE To evaluate the biomechanics of corneal ring implants by providing a related mathematical theory and biomechanical model for the treatment of myopia and keratoconus. METHODS The spherical dome model considers the inhomogeneity of the tunica of the eye, dimensions of the cornea, lamellar structure of the corneal stroma, and asphericity of the cornea. It is used in this study for calcul...
