Abstract: A system and method are provided for fragmenting a crystalline lens, to facilitate its removal from the lens bag during an ophthalmic laser surgery. First, a predetermined pattern is used to make Laser Induced Optical Breakdown (LIOB) cuts that section the lens into asymmetrical, operational segments. At least one operational segment is then selected and softened with a plurality of compact LIOB cuts. Once softened, the selected segment is aspirated. The remaining operational segments are then subsequently removed. During a procedure, an imaging unit can monitor movements of the lens bag to ensure proper placement of the LIOB cuts on the lens.

Abstract: A system and method for performing a femto-fragmentation procedure on tissue in the crystalline lens of an eye requires that a laser beam be directed and focused to a focal point in the crystalline lens of the eye. The focal point is then guided, relative to an axis defined by the eye, to create a segment cluster by causing Laser Induced Optical Breakdown (LIOB) of tissue in the crystalline lens. The resultant segment cluster includes a plurality of contiguous, elongated segments in the crystalline lens that are individually tapered from an anterior end-area to a posterior end-area. Specifically, this is done to facilitate the removal of individual segments from the segment cluster in the crystalline lens.

Abstract: A system and method are provided for docking a patient interface device to the eye of a patient using suction. The patient interface device is formed by the structural cooperation of a base member and an attachment member, both of which have an open distal end. A contact lens is formed onto the open distal end of the base member, and a continuous abutment is formed onto the open distal end of the attachment member. When the interface device is placed onto the eye of a patient, only the continuous abutment contacts the sclera of the patient. An air pocket is formed between the contact lens and the continuous abutment. The air pocket is in fluid communication with a vacuum channel. A vacuum pump is then employed to suction the air from the air pocket and draw the surface of the eye into contact with the contact lens.

Abstract: A system and method for stabilizing an eye includes a contact element that is placed in contact with the anterior surface of the eye. The purpose here is to oppose movements of the eye during an ophthalmic surgical procedure. Importantly, while it is in contact with the eye, the contact element is positioned to exert minimal pressure on the eye. This is done to avoid causing any deformations of the eye that might otherwise adversely compromise a laser beam during the ophthalmic surgery.
