Lamellar keratoplasty consists of transplanting partial-thickness donor cornea onto a complementary recipient bed. Manual lamellar dissection is technically very difficult, time-consuming, and imprecise. Also, the manually-dissected lamellar interface often has topographical irregularities that may optically degrade the best-corrected visual acuity. The femtosecond clinical laser (IntraLase FS Laser, Irvine, CA) is a recent innovation that can be programmed to produce bladeless, precise lamellar cuts at any depth with accompanying trephination cuts for both anterior and posterior lamellar transplantation. Posterior laser cuts may be used to assist in deep lamellar endothelial keratoplasty or Descemet's stripping automated endothelial keratoplasty.
板层角膜移植术包括将部分厚度的供体角膜移植到互补的受体床上。手动板层剖切在技术上非常困难、耗时且不精确。此外，手动剖切的板层界面通常存在地形不规则性，这可能会在光学上降低最佳矫正视力。飞秒临床激光（IntraLase FS激光，加利福尼亚州欧文市）是一项最新创新技术，它可以进行编程，在任何深度进行无刀精确板层切割，并伴有用于前后板层移植的环钻切割。后部激光切割可用于辅助深层板层内皮角膜移植术或Descemet膜剥脱自动内皮角膜移植术。
