Clinical Summary Of 35 Cases Of Corneal Transplantation From DCD-derived Donor In Xinjiang

Objective:To explore the acquisition process of cornea from Donation After Cardiac Death(DCD)in Xinjiang and the clinical efficacy and problems of corneal transplantation.Method:In a retrospective study,this article summarizes the general information of 54 DCD donors,collects clinical data from 33 patients undergoing DCD corneal transplantation,and observes clinical outcomes.31 patients underwent monocular keratoplasty and 2 patients underwent binocular keratoplasty.A total of 35 cases.Of the35 cases,12 were femtosecond-assisted corneal transplants and 23 were conventional corneal transplants.Observed postoperative visual acuity changes,corneal graft transparency,corneal endothelium count and immune rejection.Results:All DCD donors' families agreed to donate the cornea.Except for corneal ulcers,a total of 60 eyes were obtained for surgery.1 case had intraoperative complications,and 9 patients had postoperative complications.Among them,7 patients had rejection,1 had secondary glaucoma,and 1 had suture relaxation.At the last follow-up,corneal grafts were clear in32 eyes(91.4%),and vision in 23 eyes(65.7%)was improved to varying degrees.Conclusion:DCD corneas is an important source of corneal donors in China.It is necessary to continuously improve relevant systems and procedures to benefit more patients with corneal blindness.
