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

   University essay from KTH/Matematik (Avd.)

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

   Abstract : 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. READ MORE

3. 2. Jämförelse av olika övervakningstekniker för monitorering av neuromuskulär blockad vid ögonkirurgi : applicerbarhet av elektromyograf TetraGraph (Senzime) på hund

   University essay from SLU/Dept. of Clinical Sciences

   Author : Jonathan Sverud; [2020]
   Keywords : anestesi; övervakning; neuromuskulär blockad; acceleromyografi; elektromyografi; mekanomyografi; hund;

   Abstract : Central position av ögat är nödvändigt hos hundar som genomgår ögonoperation som innefattar cornea- och intraokulär kirurgi. Neuromuskulär blockad (NMB) har en relaxerande effekt på muskulatur och kan användas för centrering av ögat. Dessa läkemedel påverkar dock ventilationen negativt. READ MORE

   Abstract : The objectives of the present project were to set up, optimise and characterise a digitalholographic microscopy (DHM) laboratory set-up designed for the study of eyetissue and to implement and optimise digital data processing and noise reductionroutines. This work is part of a collaborative project aiming to provide quantitativemethods for the in vitro and in vivo characterisation of human corneal transparency. READ MORE

6. 5. Injectable, in situ crosslinked hydrogels by Fenton’s Reagent (Fe (II) & H2O2) for corneal perforations

   University essay from Uppsala universitet/Institutionen för medicinsk biokemi och mikrobiologi

   Author : Mehmet Nizamoglu; [2018]
   Keywords : ;

   Abstract : Corneal perforations are medical emergencies in which the cornea is partially or completely ruptured, resulting in the loss of stability of the whole eye. Such situations can be caused by bacterial or fungal keratitis, autoimmune, or ocular-surface related disorders. Corneal perforations, if left untreated, can cause partial or total blindness.
