Data analysis from ophthalmologic devices
Brož, Petr ; Hemzal, Dušan (referee) ; Kolář, Radim (advisor)
In the bechelor theses is a brief overview of anatomy, optic environment and the basic refractive errors of the eye. Listed below are the diagnostic techniques that the patient must undergo before cataract surgery (biometry, keratometry of the eye and subjective measure of visual acuity). The practical part consists of two surveys. In the first research are statistically compared (Wilcoxon paired test, Spearman's correlation coefficient) biometrics methods - acoustic and optical biometry. The second research is evaluated subjective level of uncorrected visual acuity before cataract surgery and after. At the end of this work are discussed and evaluated the results of both studies.

Modelling of the Visual Perception
Faruga, Michal ; Hemzal, Dušan (referee) ; Kolář, Radim (advisor)
This diploma thesis considers with human vision and human eye. It takes into account both anatomic view and physiology standpoints. There is, among others, description of optical processes occurring in the organ of the sight mentioned in the work. The human eye suffers from optical defects – aberrations – that are able to degrade the retinal image and ultimately visual performance. Substantial part of the text deals with these aberrations. There are also analysed possibilities of their elimination using an inverse aberration. Work also assumes opportunity to optical modeling to calculate distorted images from ocular aberration data. Practical part consist of software application created using Matlab environment ver. 6.5 as well as full documentation. The examples of outputs procured using this application are published. Both software application and detail documentation are included on CD.
