There were also markedly outlying observations. In this situation, the statistical significance of the differences was examined by the Kruskal\-Wallis nonparametric test \(with a significance level of 0.05\). The significance of intra\-group differences was evaluated by the Dunn test. The interdependence analysis included age, best corrected visual acuity, intraocular pressure and bioelements content. A correlation matrix has been created. A set of variable derivatives was then prepared to take into account not only raw variables, but also their transformations such as logarithm. Strong correlations \(ranging from 0.75 to 1.0 or \-0.75 to \-1.0\) were observed only within groups of variables of the same origin, for example, the zinc content and its transformations. The other correlations between variables from different groups were low or very low. The following results were obtained in the bioelements content of cataractous lenses in particular groups of patients\: Ca content \(median values\)\: 425 ppm \(G1\), 472 ppm \(G2\), 768 ppm \(G3\)\; Fe content \(median values\)\: 5 ppm \(G1\), 6 ppm \(G2\), 2.8 ppm \(G3\)\; Zn content \(median values\)\: 39 ppm \(G1\), 63 ppm \(G2\), 153 ppm \(G3\). The relationships and differences in bioelements between the groups of patients were shown."]
