Darba mērķis bija izstrādāt tīklenes biezuma mērīšanas metodi, izmantojot Šaka-Hartmana aberometriju. Tika izvēlēts mākslīgās tīklenes materiāls, izveidoti dažāda biezuma paraugi. Izmantojot Šaka-Hartmana aberometrus ar fokusa attālumu 3mm un 18.6mm, tika iegūti attēli, kuros novērojama dubulto punktu aina. Ar Matlab programmas kodu tika atlasīti dubultie punkti, noteikts mākslīgās tīklenes biezums.
Tika secināts, ka garāks mikrolēcu fokusa attālums ir vairāk piemērots izteiktas dubultu punktu ainas iegūšanai. Punktu ainu varēja novērtēt kvalitatīvi, nevis kvantitatīvi. Izmantotais materiāls būtiski ietekmēja mērījuma rezultātus.

The goal of the work was to design a method for measuring the retinal thickness using the Shack-Hartmann aberrometry. A material of the artificial retina was selected and samples with different thickness were created. Using Shack-Hartmann aberrometers with the focal length 3mm and 18.6mm images containing a double-spot pattern were created. Using Matlab, the double-spots were selected and the retinal thickness was determined.
It was concluded that longer lenslet focal length is more suited to acquire a pronounced double-spot pattern. The spot pattern could be evaluated only in a qualitative, not quantitative way. The selected material affected the results significantly.
