Figure 5: Fluorescein microscopy of the cornea in the DSAEK group on day 28. Fluorescein microscopic examination (A and C) and bright field micrograph (B) of flat mounts of the cornea obtained 28 days after transplantation in the DSAEK group. (A) DiI-positive cells on the HCEC collagen sheet clearly show the margin of the transplanted sheet. (B) At a higher magnification, HCECs on the collagen sheet have a regular morphology and are confluent. (C) Most cells on the collagen sheet are DiI-positive (same magnification as Figure 6B). Bars=1,000 μm (A) and 100 μm (B and C).
