Methods and devices for eye surgery
First Claim
1. 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, comprising an elongated body (2) having a proximal and a distal end and at least one central lumen extending between said ends;
- a flexible shaving filament (4) movably provided in said lumen so as to be insertable into the lens capsule;
wherein said filament has an overall stiffness such that it will be able to conform to an inner surface of a lens capsule when inserted into said capsule, and also to enable shaving off of material from said inner surface.

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.

29. A method of removing undesired tissue such as residual tissue, epithelial cells and/or other undesired material (s) from the inner surface of a lens capsule of an eye of a mammal, comprising the steps:
- introducing a flexible shaving filament into the lens capsule, comprising feeding a length of said filament into the lens capsule such that the filament is brought into contact with an inner surface of the lens capsule and conforms to said inner surface of said lens capsule when inserted into said capsule, and also to enable shaving off of material from said inner surface; and
moving the filament back and forth to cause an oscillating movement of said loop(s) so as to shave off said epithelial cells/undesired tissue/undesired material (s) from said inner surface. - View Dependent Claims (30, 31, 32, 33, 34, 35)
