Publication number: 20110112635Abstract: An accommodation measurement implant for measuring accommodation in an experimental set-up including an animal eye having a visual axis and including a sclera of tough connective tissue, an annular ciliary sulcus, and a sphincter-like ciliary body having a relaxed state for tensioning a capsular diaphragm in an anterior direction along the visual axis. The implant includes a rigid base member with a haptics system for penetrating the tough connective tissue of the animal eye's sclera for self-anchoring said base member in the animal eye's annular ciliary sulcus at least two spaced apart stationary anchor points, and having a central aperture.Type: ApplicationFiled: January 4, 2011Publication date: May 12, 2011Inventor: Yehoshua BEN NUN

Patent number: 7815678Abstract: An accommodating intraocular lens (AIOL) including a biasing mechanism for elastically deforming an elastically deformable shape memory disk-like optical element for affording the AIOL a natural positive diopter strength for near vision. The AIOL is intended to be implanted in a human eye such that relaxation of its ciliary body causes its capsular diaphragm to apply an accommodation force for overcoming the biasing mechanism to reduce the AIOL's natural positive diopter strength for distance vision.Type: GrantFiled: October 9, 2005Date of Patent: October 19, 2010Assignee: NuLens Ltd.Inventor: Yehoshua Ben Nun

Publication number: 20070185574Abstract: An accommodating lens assembly having an optical axis and being adapted to be implanted in a posterior chamber of an eye having a capsular unit located therein. The assembly includes a rigid haptics element adapted to secure the assembly within the posterior chamber outside said capsular unit. The element is transparent at least in a region around the axis. The assembly further includes a resilient body adapted to operate as a lens having a curved surface when pressed up against the region of the haptics element by an axial force applied thereto by the capsular unit. A change in this force causes a change in a radius of curvature for the curved surface.Type: ApplicationFiled: April 11, 2007Publication date: August 9, 2007Inventor: Yehoshua Ben Nun

Patent number: 6328747Abstract: A cataract removing device (CRD) in a system for surgically removing a cataract from an eye includes a cryomanipulator having a body and a manipulator head with a cryogenic tip for selectively freeze-gripping a region of contact of the cataract and for manipulating it within the eye. The cryomanipulator may also include a surgical tip and a heating device. The cryomanipulator may further include a sleeve having an aperture associated with a supply of liquid for providing irrigation of the eye. The sleeve may be also associated with a vacuum suction device for producing suction at the aperture. The CRD is designed for breaking up the cataract while it is at least partially frozen by the cryomanipulator. The CRD includes a drilling unit for breaking the cataract and a handle for manipulating the drilling unit within the eye.Type: GrantFiled: September 18, 1998Date of Patent: December 11, 2001Assignee: ITOS Innovative Technology In Ocular Surgery, Ltd.Inventor: Yehoshua Ben Nun

Patent number: 6045535Abstract: A surgical sealing sleeve (1, 32) for preventing undesirable leakage from the humoral fluid filled interior of a mammal organ to an access environment during its temporary seating in an access tissue to the mammal organ. The surgical sealing sleeve (1, 32) has an axially extending rigid tubular sleeve (2) for attachment to the access tissue and having an axially extending passageway (5). The sleeve (2) includes an inner sleeve member (3, 33) nested at least along a portion of its length within an outer sleeve member (4). Each of the inner and outer sleeve members has a proximal end and a distal end, the inner sleeve member (3, 33) having at least one distally directed sheath support member 9(A and 9B, 34) terminating proximal to the distal end of the outer sleeve member.Type: GrantFiled: December 9, 1998Date of Patent: April 4, 2000Assignee: One Way Ocular Technology Ltd.Inventor: Yehoshua Ben Nun
