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.

Processing and analysis of ophthalmologic images and data
Brož, Petr ; Hozman, Jiří (referee) ; Kolář, Radim (advisor)
In this work is describe anatomy and physiology of the cornea. The following are the primary non-inflamatory degeneration of the cornea. Then describe the physical principles diagnostic devices for cornea – keratometer, pachymeter, Michelson interferometr and optical coherence tomography (OCT). At the end of the theoretical introduction is describes the principle of laser correction surgery – LASIK. The practical part is divided into two main objectives. The first task is propose an algorithm for automatic detection of corneal surface and then calculation of corneal thickness and size of the chamber angle in Matlab. The aim of the second task is image flap analysis for boundary detection.
