After that, tear film osmolarity was obtained with the TearLab Osmolarity System (TearLab Corporation, San Diego, CA, USA) for quantification of dry eye disease. Four groups were formed depending on tear film osmolarity: group 1 (&lt;300\u2009mOsm\/L), group 2 (300\u2013310\u2009mOsm\/L), group 3 (311\u2013320\u2009mOsm\/L) and group 4 (&gt;320\u2009mOsm\/L). Intraclass correlation coefficient (ICC) and vector analysis were calculated to assess the repeatability of keratometry and astigmatism measurements.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      ICC values for keratometry were 0.957 or higher in all osmolarity groups. Highest ICC values for astigmatism were in group 1 with the Pentacam (0.986) and in group 2 (0.979), group 3 (0.951) and group 4 (0.950) with the IOL\u2010Master 700 respectively. Highest astigmatism ICC value for the Galilei G6 was 0.884 in group 4 and the lowest in group 3 (0.405). Vector analysis of astigmatism showed no statistically significant difference between the osmolarity groups and IOL\u2010Master 700 (\n                      <jats:italic>p<\/jats:italic>\n
