초록

목적: 펨토초레이저를 이용한 데스메막박리 각막내피층판 이식술 후 장기 임상 결과를 평가하고 이를 보고하고자 한다. 대상과 방법: 각막내피부전을 가진 11명 11안에서 펨토초레이저를 이용하여 데스메막박리 각막내피층판 이식술을 시행하고 12개월 이상 추적 관찰된 환자의 의무기록을 후향적으로 분석하였다. 술 전과 술 후 최대 24개월까지 최대교정시력, 현성굴절검사, 안압 등을측정하고 술 후 합병증을 평가하였다. 결과: 평균 경과 관찰 기간은 18개월이었으며, logMAR로 환산한 최대교정시력은 술 전 1.26에서 술 후 3개월에 0.80으로 통계적으로유의한 향상을 보였고(p<0.05) 이후 안정적으로 유지되었다. 11안 모두 술 후 공여각막편은 안정적으로 부착되었으며 각막 내피세포수는 점차 감소하였고 다양한 정도의 공여-수여 각막 경계면 혼탁과 이중굴절입자들이 관찰되었다. 결론: 펨토초 레이저를 이용한 데스메막박리 각막내피층판 이식술은 공여각막편을 효과적으로 제작하는 데 도움을 주었고 술 후 빠른회복 속도를 보였으며 난시값이 적었다. 하지만 술 후 각막내피세포수의 빠른 감소를 보여 이에 대한 향후 대응 방안이 필요할 것이다.

Abstract

Purpose: To evaluate the long-term clinical outcomes of femtosecond LASER-assisted Descemet’s stripping endothelial keratoplasty (DSEK). Methods: The clinical results of endothelial keratopathy from 11 consecutive patients who were followed up for at least 12months after femtosecond LASER-assisted DSEK were retrospectively analyzed. The best corrected visual acuities (BCVA), manifest refractions, intraocular pressures, and perioperative complications were evaluated preoperatively and up to 24 months after the femtosecond LASER-assisted DSEK. Results: The average follow-up period was 18 months. Postoperative visual acuity had significantly improved from 1.26(logMAR) to 0.80 (logMAR) at 3 months (p < 0.05) and this change was maintained during postoperative follow-up. All eyes underwent successful transplantation and the donor discs were well-attached. The mean endothelial cell density continued to decrease during the follow-up period. The donor-recipient stromal interface was the area where varying degree of haziness and birefringent particles were found. Conclusions: The femtosecond LASER-assisted DSEK was effective in creating an endothelial donor disc which resulted in rapid visual recovery and low surgically-induced astigmatism. However, the operation caused rapid decrease in endothelial cell density which requires continuing further consideration by the physician.
