Figure 4. Transparency and biomechanical properties of the cornea depend on the structure and organization of corneal stroma. Scanning
electron microscope (SEM) images of the HKL showed that the Bowman's membrane structure maintained its native conformation
(A: 3500×, scale bar 5μm). Collagen fibers and fibers interconnecting to the network formed collagen bundles, which were regular
and parallel to the corneal surface (B: 100×, scale bar 100 μm). These were similar to those observed in normal human corneas.
