DIC image of HA distribution over a large senofilcon A lens area.
Notes: The master image of the HA network distributed over the entire lens area was prepared by stitching sequential images recorded using a 10× objective. Randomly chosen areas were examined using 20× magnification to visualize HA on the entire lens surface. The beads (fiducial marks) were used to identify fine details.
Abbreviations: DIC, differential interference contrast; HA, hyaluronic acid.
