Fig. 4From: Comparison of femtosecond laser-assisted corneal intrastromal xenotransplantation and the allotransplantation in rhesus monkeysSlit lamp biomicrographs. Preoperative and postoperative ocular observation of rhesus monkeys. After 6Â months of surgery, the host cornea exhibited high level of tolerance of the graft, and the graft remained high level of the clarity (a). Under retroillumination observation (b), at 6-month post-surgery, the cornea remained clear with no haze, no detectable reaction in anterior chamber or any other adverse response. The boundary of the graft became undetected after 6Â months of surgery in all groups. The boundary of the graft was marked by white arrowsBack to article page
