    • A method and apparatus for performing surgery inside the human retina (26) using fluidic internal limited membrane separation (FILMS) to remove the internal limiting retinal layer (22) from the neural retinal layer (26) at the macula, is claimed. The method comprises inserting a hollow microcannula (14) between the retinal internal limiting membrane (ILM) (22) and the neural retinal layer at or near the macula and injecting a sterile fluid (20), such as sodium hyaluronate, through the microcannula (14) and thereby raising the macular ILM retinal layer (22) away from the neural retina (26) such that it can then be removed by conventional means, while simultaneously smoothing the neural retina (26) by localized pressure. The microcannula (14) maintains a distal end (12) shaped to conform tangentially to the retinal surface (26). The sharply beveled distal tip (14) is adapted for fluid discharge, and easy insertion under the ILM retinal layer (22).
    • 声称使用流体内部有限膜分离(FILMS)在人眼视网膜(26)内进行手术以在黄斑处从神经视网膜层(26)去除内限制性视网膜层(22)的方法和装置。 该方法包括在视网膜内界膜(ILM)(22)和黄斑处或黄斑附近的神经视网膜层之间插入中空微型插管(14),并通过微型插管注射无菌流体(20)如透明质酸钠 从而使黄斑ILM视网膜层(22)远离神经视网膜(26),从而可以通过常规手段将其除去,同时通过局部压力平滑神经视网膜(26)。 微型插管(14)保持成形为切向与视网膜表面(26)一致的远端(12)。 尖锐的远端尖端(14)适于流体排出,并且易于插入ILM视网膜层(22)下方。
