MICROFEMTOTOMY METHODS AND SYSTEMS
Methods and systems for performing laser-assisted surgery on an eye form one or more small anchoring capsulotomies in the lens capsule of the eye. The one or more anchoring capsulotomies are configured to accommodate corresponding anchoring features of an intraocular lens and/or to accommodate one or more drug-eluting members. A method for performing laser-assisted eye surgery on an eye having a lens capsule includes forming an anchoring capsulotomy in the lens capsule and coupling an anchoring feature of the intraocular lens with the anchoring capsulotomy. The anchoring capsulotomy is formed by using a laser to incise the lens capsule. The anchoring feature can protrude transverse to a surface of the intraocular lens that interfaces with the lens capsule adjacent to the anchoring capsulotomy.

28 . A method for performing a laser-assisted treatment of an eye having a lens capsule, the method comprising:
forming an anchoring capsulotomy in the lens capsule by using a laser to incise the lens capsule, the anchoring capsulotomy being configured to accommodate a drug eluting member; and
removably coupling the drug eluting member to the anchoring capsulotomy, wherein a mechanical feature of the drug eluting member is removably fitted through the anchoring capsulotomy to retain the drug eluting member's position relative to the lens capsule.
29 . A system for performing a laser-assisted treatment of an eye having a lens capsule, the system comprising:
a laser source configured to produce a treatment beam comprising a plurality of laser pulses;
an integrated optical system comprising an imaging assembly operatively coupled to a treatment laser delivery assembly such that they share at least one common optical element, the integrated optical system being configured to acquire image information pertinent to one or more targeted tissue structures and direct the treatment beam in a three-dimensional pattern to cause breakdown in at least one of the targeted tissue structures; and
a controller operatively coupled with the laser source and the integrated optical system, the controller being configured to control the system to cut an anchoring capsulotomy in the lens capsule, the anchoring capsulotomy being configured to accommodate a drug eluting member, wherein a mechanical feature of the drug eluting member is configured to be removably fitted through the anchoring capsulotomy to retain the drug eluting member's position relative to the lens capsule.
30 .- 51 . (canceled)
52 . The system of claim 29 , wherein the controller is further configured to control the system to cut a central capsulotomy in the lens capsule, wherein the anchoring capsulotomy is adjacent to the central capsulotomy.
53 . The system of claim 29 , wherein the controller is further configured to control the system to cut a plurality of anchoring capsulotomies, wherein the anchoring capsulotomies are located in an anterior capsule of the eye, or in a posterior capsule of the eye, or in both the anterior and posterior capsules.
