Embodiment Construction

[0038] Microsurgery / Capsulotomy Devices

[0039] Embodiments of the invention are described herein in the context of lens capsule surgery in which a portion of the anterior surface of the lens capsule is cut. This technique can be used to perform cataract treatments in which all or a portion of the lens located within the lens capsule is removed from the eye. The process can also be used to create an access hole in the lens capsule through which an intraocular lens (such as an intraocular lens or IOL) is implanted in the lens capsule. Although generally described here in terms of performing lens capsule surgery, the device and procedure are not limited to lens capsule surgery, but may also be used in other treatments of the eye, such as corneal surgery, glaucoma treatment, micro-fenestration of the optic nerve , Surgery involving the Descemet's membrane, etc. In addition, the device and process can also be used for the delivery of pharmaceuticals, biological and chemical age...

Abstract

A surgical device and procedure are provided for smoothly and easily accessing tissue to perform microsurgery, including a capsulotomy of a lens capsule of an eye. The device includes a handpiece with a tip for insertion into an incision in the cornea of the eye. A sliding element is disposed within the handpiece and a suction cup is mounted to the sliding element. The sliding element can be translated to move the suction cup into and out of the handpiece. A compression mechanism associated with the suction cup and the handpiece compresses the suction cup for deployment through the tip of the handpiece. The suction cup can expand inside the anterior chamber into a cutting position on the lens capsule. A cutting element mounted to the suction cup is used to cut a portion of the lens capsule and to remove the portion from the eye.

Description

technical field [0001] The present invention relates generally to microsurgery of tissue, and more particularly to methods and devices for accessing tissue through another tissue layer in order to cut or otherwise manipulate the tissue. For example, the process and device may be used to deliver an ophthalmic surgical device through the cornea to the anterior lens capsule in the anterior cavity of the eye. Background technique [0002] Lens cataracts are the leading cause of blindness in the world and surgical treatment by cataract removal is the treatment of choice. A cataract is a clouding that develops within the lens of the eye or its capsule. The formation of opaque areas within the lens blocks light from passing through. The lens of the eye can be considered transparent. If the lens develops an opaque area, such as a cataract, the lens must be surgically removed. Without a lens in the eye, bulky corrective glasses are needed to focus the image on the retina. Howeve...
