Figure 2. Clinical results at 1 year after surgery. Five eyes of the treated group displayed avascular and re-epithelialized corneas, with no signs of limbal stem cell deficiency (B, C, E, F, and G), one animal showed corneal neovascularization (A), one stayed with a stromal leucoma (D) and the other suffered from neovascularization that regressed thereafter leaving a stromal leucoma (H). Figure I shows one eye of the control group with no implant, at 3 months. The 3 animals of the control group implanted with PPP showed signs of limbal stem cell deficiency: one rabbit had to be sacrificed at 120 days because of a severe infection due to a IV grade corneal abscess (J), another spontaneously died at 240 days showing a small inferior leucoma and epithelial defects (K) and the remaining rabbit displayed total irregularity of the corneal surface at one year after surgery (L).
