Abstract: A device for removing undesired tissue such as residual tissue, epithelial cells and/or other undesired material(s) from an inner surface of a lens capsule of an eye, includes an elongated body [2] having a proximal and a distal end and at least one central lumen extending between the ends. A flexible shaving filament (4) is movably provided in the lumen so as to be insertable into the lens capsule. The filament has an overall stiffness such that it will be able to conform to an inner surface of a lens capsule when inserted into the capsule, and also to enable shaving off of material from the inner surface. The invention also relates to a method for removing the undesired tissue is also disclosed.

Abstract: A device (10) for preventing leakage of gas from a lens capsule of an eye, to which a capsulorhexis has been made, during manipulations performed inside the lens capsule. It includes a tube (12) having at least one lumen (14). The tube is provided with at least one barrier member (16; 17) such that gas that has been introduced into the lens capsule is prevented to escape therefrom. It also relates to a method of eye surgery. It includes making an incision to gain access to the interior of an eye. Making a capsulorhexis in the lens capsule. Removing the lens from the lens capsule of an eye. Sealing the capsulorhexis with a sealing device, to provide gas leakage proof sealing. Expanding the lens capsule with a gas. Performing a desired operation inside the expanded lens capsule.

Abstract: The invention relates to a method of performing ocular surgery, after an anterior capsulotomy has been made, by forming a sealed expanded capsular bag. The method includes sealing the capsular bag with a viscoelastic material to provide a gas tight seal to prevent leakage into the anterior chamber of the eye during the surgical process; expanding the capsular bag by introducing a gas capable of exerting a pressure on the inner surface of the capsular bag wall; inspecting and/or treating the capsular bag with one or several devices and/or agents suitable for performing inspection and/or treatment. The inspection and/or treatment can comprise any of visual inspection, estimation of capsular bag volume; labeling any residual epithelial cells to detect the presence thereof; removing residual epithelial cells, implanting one or more intracapsular implants; injecting a lens forming material for molding a lens in situ; drying the lens capsule; alone or in any combination.

Abstract: A method for treatment of residual lens epithelial cells is disclosed. The method provides increased safety during local treatment in ocular surgery by improved administration of active agents. The method is particularly useful in treatment of proliferative events in ocular surgery, such as posterior capsular opacification.
