目前随角膜移植操作技术的提高,对供眼角膜话性的重视及手术器械、缝合材料的改进,使手术因素导致的角膜移植失败率下降,而移植免疫反应成为角膜移植失败的主要原因。因之也成为角膜移植研究的重要课题。对于移植免疫反应实验研究,其实验模型是必不可缺的。由于角膜居眼球前表面.组织透明,结构、变化单纯、便于观察。因此角膜移植免 At present, with the improvement of operation techniques of corneal transplantation, the attention paid to the corneal ophthalmology and the improvement of surgical instruments and suture materials, the corneal graft failure rate caused by surgical factors is decreased. However, the graft immune response is the main reason for the failure of corneal transplantation. It has also become an important issue of corneal transplantation research. Experimental studies on transplantation immune response, the experimental model is essential. Because the cornea lives in front of the eye surface, the tissue is transparent, the structure is simple and the change is easy to observe. Therefore, corneal transplantation free
