Patent number: 9011532Abstract: An intraocular lens is disclosed, with an optic that changes shape in response to a deforming force exerted by the zonules of the eye. A haptic supports the optic around its equator and couples the optic to the capsular bag of the eye. Certain haptic features improve the accommodative performance of the haptic, such that compressive/tensile forces may be more efficiently transferred from the haptic to optic. Furthermore, certain aspects also provide enhanced bag-sizing capability so that the IOL better fits within the capsular bag.Type: GrantFiled: July 15, 2013Date of Patent: April 21, 2015Assignee: Abbott Medical Optics Inc.Inventors: Timothy Bumbalough, Rakhi Jain, Scott J.

Publication number: 20140236068Abstract: A method of treating glaucoma in an eye by managing fluid flow past an implanted shunt having an elastomeric plate and a non-valved elastomeric drainage tube. The plate is positioned over a sclera of the eye with an outflow end of the elastomeric drainage tube open to an outer face of the plate. An inflow end of the drainage tube tunnels through the sclera and cornea to the anterior chamber of the eye. The plate may have regions of greater propensity for cell adhesion alternating with regions of lesser cell adhesion. For example, regions of texturing around the plate or drainage tube may be provided to control the size of a bleb that forms over the implant. The effective surface area of the plate may be balanced against a number of fenestrations. The drainage tube has a reduced profile and may be shaped with a non-circular external cross-section to reduce its height. A scleral groove may be used to further reduce the height of the drainage tube on the sclera.Type: ApplicationFiled: February 26, 2014Publication date: August 21, 2014Applicant: Abbott Medical Optics Inc.Inventors: Marrie H.

Patent number: 8518028Abstract: The accommodative properties of the natural lens of an eye, which tend to degrade with age, can be enhanced, restored, or otherwise improved using the in situ treatment techniques and methodologies provided here. One exemplary method of enhancing accommodative properties of the natural lens of an eye involves an initial step of specifying treatment areas of the natural lens. These treatment areas correspond to regions of the capsular bag or regions of the crystalline lens. The method continues by increasing stiffness of the treatment areas while all or portions of the natural lens remains in situ. This results in stiffened areas of the natural lens that enhance transfer of ciliary muscle forces to a center region of the crystalline lens.Type: GrantFiled: September 30, 2009Date of Patent: August 27, 2013Assignee: Abbott Medical Optics Inc.Inventors: Daniel G Brady, Rakhi Jain
