1. 1. Modelling of Corneal Surface - A Method for Reconstruction of Corneal Surface in a Wearable Eye Tracking Device

   Master-uppsats, KTH/Matematik (Avd.)

   Författare :Johanna Frost; [2022]
   Nyckelord :applied mathematics; modelling; optimization; regression; computer vision; tillämpad matematik; modellering; optimering; regression; datorseende;

   Sammanfattning : We investigate a method for reconstructing the anterior corneal surface using wearable eye tracking devices. The presented method assumes that the four reflection points from two light sources viewed by two cameras lie on a locally spherical surface of a cornea. LÄS MER

3. 2. Correlation between Corneal Radius of Curvature and Corneal Eccentricity

   Kandidat-uppsats, Institutionen för medicin och optometri (MEO)

   Författare :Patrik Fredin; [2013]
   Nyckelord :corneal radius of curvature; corneal eccentricity; topography; conic sections; corneal shape descriptors;

   Sammanfattning : Aim: The primary aim of this study was to find if there is any correlation between the corneal radius of curvature and its eccentricity. Method: 45 subjects participated in this study, 24 emmetropes, 18 myopes and three hyperopes. All subjects were free of ocular abnormalities and had no media opacities. LÄS MER
