| Outline of Final Research Achievements |
For the ophthalmic application of optically-cleared tissues, their modification and animal experiments were investigated in this study. This study focused on the amnion that were widely used in the ophthalmology field, and examined their biocompatibility in vivo and also improvement in the tolerance to a suture and transparency. Firstly, it was confirmed that no inadequate biological responses to the optically-cleared amniotic membrane were observed during the transplanted into rabbit corneal stroma. Next, further functional refinements of the optically-cleared amnion, and additional tissue optical clearing were also induced. Further optical-clearing was effective to improve the transparency of the refinement processes. Furthermore, the improvements of mechanical properties were confirmed that it was possible to improve the mechanical property to about 10 times of the original amnion, and that the corneal transplantation, which requires a tight suture, was also possible.
