Abstract:

Embodiments of the invention provide hydrodissection and/or PCO prevention or reduction in a patient undergoing eye surgery. In one embodiment, the invention is a surgical device for cutting and excising a portion of tissue, for example in performing a lens capsulotomy. A capsulotomy tip is inserted into an eye through an incision in the surface of the eye. The capsulotomy tip includes a suction cup to provide suction to the lens capsule. Then suction is applied via the suction cup to secure the capsulotomy tip to the eye. In some embodiments, after the capsulotomy tip is secured to the lens capsule, a cutting element of the capsulotomy tip is used to cut a tissue of the eye. Fluid is pushed through the capsulotomy tip and the capsulotomy tip is removed from the eye. Moreover, disclosed is an intraocular lens (IOL) to be used in conjunction with the surgical device.
