角膜移植术后的排斥反应,对那些角膜没有或仅有少量新生血管,而且植片直径在6mm以下的病例来说,反应较轻,对植片透明的影响也较小。但对患有全角膜粘连性白斑、角膜葡萄肿等角膜长满了新生血管,并且植片较大(7mm以上)的病例,则术后排斥反应发生率高,症状也重,植片也很难保持透明。这已为许多学者的临床实践所 Rejection after corneal transplantation, for those with no or only a small number of corneal neovascularization, and the diameter of the implant less than 6mm cases, the response is less, the transparency of the implants less. However, the cornea with corneal adhesion of leukoplakia, corneal staphyloma and other corneal covered with neovascularization, and the larger graft (7mm above) cases, the incidence of postoperative rejection is high, the symptoms are heavy, the implant is also very Difficult to keep transparent. This has been the clinical practice of many scholars
