AS-OCT observation. a The corneal shape was stable throughout the 6-month observation period, and no graft discharge was observed. b Corneal thickness was increased after implantation. One week after surgery, the corneal thickness of the three groups was increased, and the corneal thickness of the‘R to M’ group exhibited the most obvious increase. Central corneal thickness declined after 1 week of surgery, and there was no significant difference in △thickness at 1-month post-surgery. The △thickness values are expressed as the mean ± SD (standard deviation). Statistically significant differences are compared with the 1 week postoperatively and indicated by *P < 0.05. (Allotranplantation group: P1 m = 0.005, P3 m = 0.009, P6m < 0.001; Human to Monkey group: P1 m = 0.002, P3 m = 0.014, P6m = 0.005; Rabbit to Monkey group: P1 m = 0.011, P3 m = 0.015, P6m = 0.009)
