ATTENUATED RF POWER FOR AUTOMATED CAPSULORHEXIS

摘要

A capsulorhexis apparatus includes a capsulorhexis probe configured for insertion into an eye through an incision and a pulse generator configured to deliver at least one radio-frequency (RF) pulse to the capsulorhexis probe. The delivered RF pulse has a pre-determined attenuation profile such that the power level of the delivered RF pulse is substantially attenuated over the RF pulse's duration. In some embodiments, the pulse generator is configured to deliver a series of two or more RF pulses to the eye, such that the energy of each of the second and subsequent pulses of the series is substantially attenuated relative to the energy of the immediately preceding pulse.

1. A method for performing capsulorhexis, comprising:
inserting a capsulorhexis probe into the anterior chamber of an eye; positioning a portion of the capsulorhexis probe in contact with the anterior lens capsule of the eye; and delivering a first radio-frequency (RF) pulse to the eye, via the capsulorhexis probe, wherein the delivered first RF pulse has a pre-determined attenuation profile over a duration of the first RF pulse such that a power level of the delivered first RF pulse is attenuated by at least one-half over the duration of the first RF pulse.
