Nonparametric meshing algorithms
Nonparametric meshing algorithms
Creating non-parametric meshing algorithms allows the meshing of both regular and irregular geometries with uniform meshes. The algorithm was built to model contact lenses, but it was recently updated to be used in various applications. Click here to see a graphical representation

Microstructure of ocular tissues
Dr Abass investigated the micro-structure of corneal collagen distribution and orientation over the corneal cross-section. Following the suggestion that corneal surface topography may be stabilised by the angular orientation of out-of-plane lamella that insert into the limiting membrane of the anterior cornea, his research aimed to provide quantitative information about the angular orientations of these lamella across and throughout the depth of the cornea. Wide angle x-ray scattering experiments were carried out on beam-line IO2 at the UK’s national synchrotron facility, Diamond Light Source (Oxfordshire, UK).

Contact lenses modelling
Dr Abass's project with UltraVision has been graded by a panel of independent assessors as Grade A (Outstanding).
The project developed state-of-the-art contact lenses for people with vision loss due to irregular corneas. A suite of software codes was built to deal with all types of distorted corneas. This now allows any corneal profile that can be measured by an eye topography device to be modelled in our advanced FE software. The original objective in the project was to prepare for the second generation of the company KeraSoft product, however, the outputs obtained were designed to be flexible enough to be used for developing all the contact lenses produced by the company. This included the new generation of the KeraSoft lens and the recent product, Avanti (a monthly disposable contact lens).
