In vivo ultrathin Descemet stripping automated endothelial keratoplasty with a low-energy and high-frequency femtosecond laser

This case report describes the production of an ultrathin endothelial donor corneal lamella using a femtosecond laser with low energy and a high frequency. In addition, we report its use in vivo in an eye with pseudophakic bullous keratopathy. The outcomes were observed 3 months after surgery in terms of the change in endothelial donor lamella and full cornea thickness (including pachymetric mapping), visual acuity, and endothelial cell count.

本病例报告阐述了采用低能量高频率飞秒激光（femtosecond laser）制备超薄内皮供体角膜板层（endothelial donor corneal lamella）的方法。此外，本研究还报告了该板层在伴有假性大疱性角膜病变（pseudophakic bullous keratopathy）的眼部的体内应用情况。术后3个月时，本研究从内皮供体板层与全角膜厚度变化（包括角膜测厚地形图（pachymetric mapping））、视力以及内皮细胞计数这几个方面对手术结局进行了观察评估。
