Problems solved by technology

This loss of the vitreous can lead to subsequent retinal detachment and / or intraocular infection
Also, although some ophthalmic procedures may also require a posterior capsulorhexis, current devices designed for anterior capsulorhexis do not have the optimal geometry for performing a posterior capsulorhexis

Abstract

Various embodiments of a capsulotomy repair device include a resistive-heating element comprising an electrically resistive, superelastic wire forming a loop between first and second ends of the superelastic wire. The first and second ends of the loop may at least partially extend at an angle from a planar face defined by the loop, to an insulating portion, to form a transitional neck between the loop and the insulating portion. The capsulotomy repair device may be positioned in the eye relative to a capsularhexis perimeter to overlap tears in the capsularhexis periemeter to remove the tears by forming an adjusted capsularhexis perimeter by burning around the tear.

Description

technical field [0001] The present invention relates generally to the field of ophthalmic surgery, and more particularly to methods and apparatus for performing capsulorhexis. Background technique [0002] An accepted treatment for treating cataracts is surgical removal of the lens (eg, by phacoemulsification) and replacement of the lens' function by an intraocular lens (IOL). Before the cataractous lens is removed, an opening or tear can form in the anterior capsule. During phacoemulsification, there may be tension on the incision edge of the anterior capsulorhexis as the nucleus of the lens is emulsified. Also, if the capsular bag breaks with multiple small capsular lacerations, the small tail that remains may result in radial capsular lacerations that can extend into the posterior capsule. Such radial breaches may cause complications as they may destabilize the lens for further cataract extraction and subsequent safe placement of the intraocular lens within the lens cap...
