The Effect of High Intensity Focused Ultrasound Keratoplasty on Rabbit Anterior Segment

Figure 3

Hematoxylin-eosin staining of the cornea at different time points. (A) 1 day after the operation, the focal zone is deeply stained (indicated by an arrow), the fibers of the focal zone were swollen and fused, 400x; (B) 7 days after the operation, the focal zone showed a lighter staining, and the epithelium was hyperplastic (indicated by an arrow), 400x; ((C), (D), and (E)) 15 days, 30 days, and 60 days after operation, the focal zone disappeared and the epithelium was hyperplastic (indicated by an arrow). The fibers shrunk and became distorted, 400x; (F) 90 days after operation, epithelial hyperplasia was significantly reduced, and the matrix fibers were arranged in order, 400x; (G) hematoxylin-eosin staining of a cornea in the control group, 400x. Scale bar = 100 μm.
