Objective: To summarize the therapeutic effect and experience of penetrating keratoplasty on corneal leukoplakia after corneal perforation. Methods: Penetrating keratoplasty was used to treat eleven eyes and 11 eyes of corneal perforation with corneal leukoplakia, and the indexes such as the retention of the eyeball, the transparency of the graft and the postoperative visual acuity were observed. Results: The eyeballs of 11 eyes were preserved in all cases from March to 8 years postoperatively. Eight eyes were transplanted transparently (72.7%) and three eyes were partially translucent (27-3%). The visual acuity of 9 eyes was increased Eyes get 0.05 or more of vision. Conclusion: Penetrating keratoplasty is an effective method for the treatment of corneal leukoplakia after corneal perforation caused by various causes. Good anesthesia and a variety of measures to prevent intraoperative eye prolapse, rational surgical design and reasonable viscoelastic agent Use helps to improve the treatment effect.
