Capsulotomy is a type of eye surgery in which an incision is made into the capsule of the crystalline lens of the eye. In modern cataract operations, the lens capsule is usually not removed. The most common forms of cataract surgery remove nearly all of the crystalline lens but do not remove the crystalline lens capsule (the outer “bag” layer of the crystalline lens). The crystalline lens capsule is retained and used to contain and position the intraocular lens implant (IOL).

System and method of performing femtosecond laser accomodative capsulotomy
Disclosed is a system and method for making a first incision in an anterior capsule of a capsular bag, the first incision being less than or equal to approximately 3.5 mm in diameter and making a second incision in the anterior capsule, the second incision being less than or equal to approximately 3.0 mm in diameter. The first incision and the second incision are positioned off-center from a center portion of the anterior capsule. The method includes performing lens fragmentation of a lens in the capsular bag to yield lens material, inserting a first instrument into the first incision, inserting a second first instrument into the second incision and removing the lens material via one of the first instrument and the second instrument and through one of the first incision and the second incision. The tensile structure of the anterior portion of the capsular bag is maintained such that accommodation exists within the eye after insertion of the intraocular lens.

A system and tool for performing a capsulotomy procedure. The system includes an air pressure unit, a capsulotomy and movement control unit providing electrical current and movement control, and a capsulotomy tool, and an extendable-retractable burning element coupled to the tool. A capsulotomy and movement control unit provides electrical current to the burning element and movement control for extending and retracting the burning element. When the burning element is in a flattened, retracted configuration, the tip of the tool can be inserted through a relatively small corneal incision. Then, the burning element is opened to a circular, extended configuration, allowing a capsulotomy by applying an electrical pulse to the burning element. Optionally, predefined points of weakness allow removal of the tool should breakage occur during surgery.
