Abstract

Objectives: To evaluate the 6-month outcomes of Descemet membrane endothelial keratoplasty (DMEK) in patients with pseudophakic bullous keratopathy (PBK) and Fuchs’ endothelial dystrophy (FED) in a single center in Turkey. Materials and Methods: The medical records of patients who underwent DMEK were reviewed retrospectively. Best corrected visual acuity (BCVA), donor corneal endothelial cell density (ECD), donor age, duration in solution after obtaining the donor tissue, and duration after exitus of the donor were evaluated preoperatively and BCVA, ECD, and ECD loss (%) at postoperative 6 months were evaluated postoperatively. Graft detachment, graft failure, and pupillary block were recorded as surgical complications. Patients with cataract and FED underwent combined or staged procedures. Two different graft preparation techniques were utilized: 8 and 9.5 mm. Results: One hundred eyes of 74 patients were included in the study. Fifty-two of the eyes had FED and the remaining 48 had PBK. Mean ECD loss in 6 months was 29.2±4.4% in the FED group and 29.7±5% in the PBK group (p=0.415). Mean BCVA at 6 months was 0.06±0.05 in the patients with FED and 0.07±0.05 in the patients with PBK (p=0.378). Mean ECD loss in 6 months was 28.3±5.3% in the 8 mm group vs. 29.7±4.5% in the 9.5 mm group (p=0.255), and 28.5±5.6% in the combined group vs. 29.8±2.9% in the staged group (p=0.279).Conclusion: Different graft preparation techniques can be utilized with similar efficiency for DMEK surgery. A staged or combined approach can be used efficiently in the management of patients with FED and cataract. Our results are promising both for PBK and FED patients.

Özet

Amaç: Psödofakik bullöz keratopati (PBK) ve Fuchs endotelyal distrofi (FED) hastalarında tek bir merkezde yapılan Descemet membranendotelyal keratoplasti (DMEK) cerrahisinin 6 aylık sonuçlarını değerlendirmektir.Gereç ve Yöntem: DMEK cerrahisi yapılan hastaların tıbbi kayıtları retrospektif olarak değerlendirilmiştir. Preoperatif olarak en iyidüzeltilmiş görme keskinliği (EİDGK), donör korneal endotelyal hücre yoğunluğu (EHY), donör yaşı, donör dokunun alınmasındansonra solüsyonda bekleme süresi ve kadavranın ölümünden donör dokunun alınmasına kadar geçen süre; postoperatif 6. ayda ise EİDGK,EHY ve EHY kaybı (%) değerlendirmeye alınmıştır. Greft dekolmanı, greft yetmezliği ve pupiller blok cerrahi komplikasyonlarolarak ele alınmıştır. Katarakt ve FED olan hastalarda kombine veya aşamalı cerrahi uygulanmıştır. İki farklı donör hazırlama tekniğikullanılmıştır: 8 ve 9,5 mm.Bulgular: Yetmiş dört hastanın 100 gözü çalışmaya dahil edilmiştir. Elli iki gözde FED, 48 gözde ise PBK mevcuttu. FED hastalarındaki6. ayda EHY kaybı %29,2±4,4 iken, PBK hastalarında %29,7±5 olarak bulunmuştur (p=0,415). Altıncı aydaki ortalama EİDGK FEDhastalarında 0,06±0,05 iken, PBK hastalarında 0,07±0,05 olarak bulunmuştur (p=0,378). 8 mm donör tekniği kullanılan grupta 6.aydaki EHY kaybı %28,3±5,3 iken, 9,5 mm donör tekniği kullanılan grupta %29,7±4,5 olarak bulunmuştur (p=0,255). Kombinecerrahi uygulanan grupta 6. aydaki EHY kaybı %28,5±5,6 iken, aşamalı cerrahi grubunda %29,8±2,9 olarak bulunmuştur (p=0,279).Sonuç: DMEK cerrahisinde farklı donör hazırlama teknikleri tercihi aynı etkinlikte bulunmuştur. FED ve kataraktı olan hastalardaaşamalı veya kombine yaklaşım benzer etkinlikte uygulanabilir. Sonuçlarımız hem FED hem de PBK hastaları için umut vericidir.
