OPHTHALMIC SURGICAL DEVICE FOR CAPSULOTOMY
First Claim
1. A method for performing a capsulotomy of a lens capsule of an eye, the method comprising:
- moving a capsulotomy device to a position proximate to the lens capsule of the eye, the capsulotomy device comprising a suction cup mounted to an arm and a cutting element mounted to the suction cup;
applying suction to the suction cup for securing the suction cup to the lens capsule of the eye, the suction pulling tissue of the lens capsule into the suction cup;
cutting a portion of the tissue of the lens capsule pulled into the suction cup against the cutting element;
reducing the suction applied to the suction cup for releasing the suction cup from the tissue; and
removing the capsulotomy device from the eye.

Abstract
A surgical device and procedure are provided for performing microsurgery, including a capsulotomy of a lens capsule of an eye. The device has an elastically deformable cutting element mounted within an elastomeric suction cup. The suction cup is attached to an arm for manipulating the device. The device can be inserted into the anterior chamber of the eye, through a corneal incision, to cut a piece from the anterior portion of the lens capsule of the eye. The device is secured against the lens capsule using suction applied by one or more suction elements. The device is then removed from the eye, with the cut piece of membrane retained within the device by suction.

15. A surgical device for performing a capsulotomy of a lens capsule of an eye, the device comprising:
-
a suction cup having a roof and an underside, the underside comprising an inner chamber and outer chamber; an arm attached to the suction cup for moving the device into contact with the lens capsule; one or more suction elements connected to the suction cup and for providing suction to the chambers to secure the suction cup to the lens capsule of the eye and to retain cut tissue in the suction cup; and a cutting element mounted to the suction cup, the cutting element for cutting a portion of tissue of the lens capsule pulled into the suction cup by the suction provided by the suction elements. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30)

40. A method for performing microsurgery of tissue, the method comprising:
-
moving a microsurgery device to a position proximate to the tissue, the microsurgery device comprising a collapsible suction cup mounted to an arm, the collapsible suction cup having one or more chambers, and further comprising a cutting element mounted to the collapsible suction cup, wherein the collapsible suction cup is collapsed during movement into and out of the position proximate to the tissue; applying suction to the collapsible suction cup for pulling an area of the tissue into the collapsible suction cup to secure the collapsible suction cup against the tissue and for pulling tissue into position for cutting; cutting free a portion of the tissue pulled into the collapsible suction cup against the cutting element; releasing suction from one of the chambers of the collapsible suction cup to release the collapsible suction cup from the tissue, the suction maintained in another of the chambers for holding the portion severed in the collapsible suction cup; and removing the microsurgery device from the tissue, the portion of the tissue severed remaining within the microsurgery device for removal. - View Dependent Claims (41, 42, 43, 44, 45, 46, 47)

48. A surgical device for performing microsurgery of tissue, the device comprising:
-
a collapsible suction cup having a roof and an underside, the underside comprising an inner chamber and outer chamber, wherein the collapsible suction cup is collapsed during movement into and out of proximity to the tissue, an arm attached to the collapsible suction cup configured for moving the device into contact with the tissue; one or more suction elements connected to the collapsible suction cup and configured for providing suction to the chambers to secure the collapsible suction cup against the tissue; and a cutting element disposed within the outer chamber and mounted to the collapsible suction cup, the cutting element configured to cut free a portion of the tissue pulled into the collapsible suction cup by the suction provided by the suction elements, the one or more suction elements configured for releasing the suction to release the collapsible suction cup from the tissue while providing suction to the inner chamber for retaining the portion severed during removal of the device. - View Dependent Claims (49, 50, 51, 52, 53, 54)
