Abstract

L'invention concerne un microkératome à jet d'eau utilisé pour couper une lamelle lenticulaire dans la cornée, comprenant un dispositif de serrage scléral destiné à immobiliser l'oeil pendant la découpe de la lamelle, une buse de jet d'eau, et un gabarit destiné à aplanir la cornée. Un canal correspondant à une région de bord périphérique de lamelle est formé entre le gabarit et un cylindre qui agit comme une chambre à dépression, et une dépression est appliquée audit canal afin d'aspirer le tissu cornéen dans la région de bord périphérique dans le canal, ce qui réduit la compression du tissu cornéen au niveau du bord de lamelle à couper. Le jet d'eau balaie, à une vitesse élevée, une distance prédéterminée en-dessous du gabarit afin de couper la lamelle avec une érosion négligeable au niveau du bord ou de la limite de celle-ci.
