Calibrating corneal material model parameters using only inflation data: an ill-posed problem

Author: Kok, S ; Botha, N ; Inglis, M Date: Aug 2014 Goldmann applanation tonometry (GAT) is a method used to estimate the intraocular pressure by measuring the indentation resistance of the cornea. A popular approach to investigate the sensitivity of GAT results to material and geometry ... Read more
Finite element modeling of corneal strip extensometry

Author: Botha, N ; Kok, S ; Inglis, HM Date: Dec 2012 Corneal biomechanical properties are an important element in the study of corneal biomechanics. There are currently two techniques to obtain these properties; an inflation test and the strip extensiometry test. As the inflation test has been ... Read more
Intraocular pressure estimation using proper orthogonal decomposition

Author: Botha, N ; Kok, S ; Inglis, HM Date: Jul 2012 Glaucoma is the second leading cause of irreversible blindness. The primary indicator for glaucoma is an elevated intraocular pressure, which is estimated by means of contact or non-contact tonometry. However, these techniques do not accurately ... Read more
Modelling Goldmann applanation tonometry to improve accuracy of glaucoma screening

Author: Botha, N Date: Oct 2012 This presentation outlines how the intraocular pressure inside the human eye can be estimated using numerical techniques. This can be used as a risk indicator in the diagnosis of glaucoma. Read more
