Representative histological images showing histologic findings of cornea after microneedles treatment and/or suture placement: (a) untreated eye: microneedle-treated eye imaged 1 day (b), 6 days (c), and 14 days (d) after insertion and removal of an uncoated microneedle; suture-treated eye imaged 10 days (e) and 18 days (f) after suture placement; and suture- and microneedle-treated eye imaged 10 days (g) and 18 days (h) after suture placement (microneedle treatment was performed on day 4 using a microneedle coated with 1.1 μg bevacizumab). Scale bars: 100 μm.
