Anatomical Differences of Corneal Surface Parameters

Purpose: The aim of this study was to analyze possible anatomical differences of corneal surface parameters in the sample of population and between the genders. Methods: This study is presenting the sample of population which has consisted of 1354 subjects, 794 female and 560 male eyes. Subjects were chosen randomly. To determine and evaluate all values of corneal surface parameters, auto refractor keratometer with Placido disc (KR 8100P, Topcon, Japan) and the program Software Corneal Analyzer, Version 3.0 were used. The results were registered and then processed statistically. Results: From a large amounts of data, tere are chosen only the results in this study that showed statistically significant (p<0. 05) differences between right and left eye and between the genders. Found variations are in: the steepest meridian, the axis of the steepest meridian, corneal astigmatism, astigmatic difference and corneal diameter (HVID). Conclusion: The study shows that in optometric practice is also important to pay attention not only to functional but also individual anatomical parameters of corneal surface.
