Acta of Bioengineering and Biomechanics
EN So far applanation tonometry has not worked out any theoretical basis for correcting the result of intraocular pressure measurement carried out on a cornea with noncalibration dimensions by means of the Goldmann tonometer. All the tables of instrument reading corrections for cornea thickness or corn[...]

PL Przedmiotem badań jest model strukturalny gaiki ocznej oraz możliwość symulowania za jego pomocą funkcji optycznych oka. Analizie poddano także aspekty mechaniczne pomiaru ciśnienia wewnątrzgałkowego (IOP) techniką określaną jako tonometria. Opracowanie jest próbą stworzenia podstaw teoretycznych me[...]
EN Refraction surgery, tonometry and eye optical system theory are the fields of ophthalmology, in which a biomechanical model of the eyeball could play a significant research and utilitarian role. Attempts at creating such a model have been made since the 1970s. Today when highly sophisticated systems[...]

EN A thesis that linear mechanics does not apply to the analysis of cornea load during Goldmann applanation tonometry measurement and that the concept of surface tension in the lacrimal fluid is an ineffective attempt at circumventing the associated problems is put forward. The fundamental problem emer[...]

EN The values of the biomechanical human eyeball model parameters reported in the literature are still being disputed. The primary motivation behind this work was to predict the material parameters of the cornea through numerical simulations and to assess the applicability of the ubiquitously accepted [...]

EN Attempts at the mechanical identification of the human eyeball are often not very effective for two reasons: the material parameters determined by tension tests on corneal and scleral tissue specimens are not sufficiently accurate while numerical models of the eye, integrating material and geometric[...]

EN Any generally accepted standard of modelling an eyeball’s mounting system still does not exist. The comparison of the results of two extremely different mounting models, i.e., fixed and simply supported, permits us to estimate the part of the kinematic boundary conditions in the solutions of the mod[...]
