Outline of Final Research Achievements

In this study, in vivo analysis of the cornea after DMEK was performed using laser in vivo laser comfocal microscopy and anterior segment OCT. As a result, central corneal thinning after DMEK was confirmed. Also, after the corneal epithelial removal, reduction of corneal nerves after DMEK was observed. With the help of Inami company, we developed new device for DMEK that enabled faster and safer surgeries. Also, using Ngenuity 3D visual system, new DMEK surgery is now possible with less intra- and postoperative complications.

Academic Significance and Societal Importance of the Research Achievements

本研究の学術的な特色の第一は、本邦で最多数と思われる角膜内皮移植のこれまでの症例や経験を生かし、日本人における術中術後合併症の種類や発症頻度などについて明らかになった。また、アジア人特有の術中術後合併症を克服するための新たな術式の開発や専用器具の開発を行い、より安全な角膜内皮移植術(DMEK)が可能となった。また、レーザー生体共焦点顕微鏡や新型前眼部OCT、OCT手術顕微鏡等を駆使して、角膜内皮移植術後角膜組織の詳細な生体解析を行った。さらに、DMEK対するNGENUITY3Dビジュアルシステムの有用性が確認された。
