Design and optimization of topography based customizable mini-scleral contact lenses

Cornea disorder diseases, like keratoconus, are characterized by progressive thinning and distortion of the apical cornea that leads to complex optical aberrations due to either irregular astigmatism or corneal scarring. For patients with irregular cornea, corneal contact lenses no longer fit and become intolerable with discomfort. In such cases, scleral and mini-scleral (MS) contact lenses are an attractive option. The objective of this project is to develop a mathematical model for predicting optimum profile of MS lenses that is customizable for individual irregular cornea.
