Endothelial keratoplasty using donor tissue not suitable for full-thickness penetrating keratoplasty.

摘要: PURPOSE To evaluate the use of corneal donor tissue deemed unsuitable for full-thickness penetrating keratoplasty (PK) in deep lamellar endothelial (DLEK) and to compare postoperative results those DLEK surgery using that is suitable PK. METHODS Small-incision was performed 39 corneas Thirty-five donors had anterior scars or opacities, 3 pterygia within 8-mm zone, 1 prior LASIK. All preparation completed by manual stromal dissection. The surgical courses were reviewed. Preoperative 6-month this study group compared with a control consisting first 55 consecutive small-incision patients receiving no criteria excluding them from Four eyes eye confounding variables presence an anterior-chamber lens vitrectomy macular disease recipient eye. RESULTS There significant difference preoperative measurements best spectacle-corrected visual acuity (BSCVA; P = 0.372), cell density (ECD; 0.749), topography [surface regularity index (SRI), 0.485; surface asymmetry (SAI), 0.154] between 2 groups. For unacceptable PK, at 6 months after surgery, vision (P 0.002) improved significantly before (SRI, < 0.001; SAI, 0.001), there change refractive astigmatism 0.240). postoperatively overall group, mean 20/56 20/43 0.015). If known cystoid edema (CME) are removed each 0.110), average BSCVA PK equal 20/48 (range, 20/25-20/200) PK-acceptable 20/20-20/80). 1.12 +/- 0.99 D 0.00-4.00 D), count 2064 396 cells/mm(2) 1208-2957 cells/mm(2)). 0.443), 0.567), 0.332; 0.110) who received CONCLUSIONS Endothelial such as broadens pool enabling cannot be used selective transplantation without deleterious results.
