Localized Shockwave-Induced Tissue Disruption
First Claim
1. A method for removing ocular tissue from a localized portion of an eye during eye surgery, the method comprising:
- generating one or more electrical pulses;
delivering one or more focused shockwaves to ocular tissue within a portion of an eye by applying the generated electrical pulses to at least one electrode of a high-intensity pulsed-electrical-field (HIPEF) probe; and
removing from said portion of the eye ocular tissue disrupted by said one or more focused shockwaves.

Abstract
A high-intensity pulsed-electrical-field (HIPEF) apparatus removes ocular tissue from a localized portion of an eye by delivering one or more focused shockwaves to that tissue. In one embodiment, for example, the apparatus generates one or more electrical pulses, delivers the one or more focused shockwaves to ocular tissue by applying the generated electrical pulses to a HIPEF probe, and then removes the ocular tissue disrupted by the one or more focused shockwaves via aspiration. To mitigate risk of damage to adjacent ocular tissue, the apparatus delivers the one or more focused shockwaves with energy substantially limited to the tissue being removed. The HIPEF apparatus is, therefore, especially advantageous in the context of cataract surgery where cataract tissue need be broken apart and removed without damaging adjacent tissue associated with the lens capsule required to implant an intraocular lens.
