The implantable Collamer lens (ICL) vault was measured in three light conditions: room light, scotopic, and photopic conditions. Pupillary diameter was recorded in three light conditions using ASOCT and ImageJ software. The primary outcome measure was the change in ICL vault from baseline (room light) to scotopic and photopic conditions, respectively.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>\n                      The mean age of participants was 22.33 \u00b1 3.1 years. V4c ICL implantation was done for a mean refractive error of \u221210.08 \u00b1 4.0D. The mean ICL vault in room light, scotopic, and photopic conditions were 568.57 \u00b1 215.83 \u00b5m, 567.47 \u00b1 225.11 \u00b5m, and 418.4 \u00b1 210.04 \u00b5m, respectively. As compared to room light, there was no significant change in the ICL vault in scotopic condition (\n                      <jats:italic toggle=\"yes\">P<\/jats:italic>\n                      = 0.89), but it was significantly decreased in photopic (\n                      <jats:italic toggle=\"yes\">P<\/jats:italic>\n                      &lt; 0.0001) condition. On regression analysis of change in vault in relation to the change in pupillary diameter, it was found that in photopic condition with every 1 mm decrease in pupil diameter as measured with ImageJ and ASOCT, there was a decrease in vault of 59.51 \u00b5m and 56.19 \u00b5m, respectively.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n
