Patent number: 8449611Abstract: An intraocular lens comprises an optic portion having a peripheral edge and at least two haptics. Each haptic is integrated with the peripheral edge of the optic portion by a corresponding haptic integration region. Also, each haptic comprises a distal segment region and a deformation segment region. The distal segment region has an outer distal length bounded by a proximate endpoint and a distal endpoint on an outer surface of the haptic, and is scribed by a distal segment angle ? of 20° to 30°. The distal segment angle has a segment origin that lies within a radial segment bound by a radial distance 1.5 mm to 1.9 mm from an optic center and a segment angle ? of from 30° to 45° from a vertical axis. The vertical axis extends through the distal endpoint of at least one haptic and the optic center.Type: GrantFiled: April 1, 2010Date of Patent: May 28, 2013Assignee: Bausch & Lomb IncorporatedInventor: Gary A.

Publication number: 20100152848Abstract: A system includes an intraocular lens configured to replace a natural crystalline lens of an eye. The system also includes one or more scleral prostheses configured to be inserted into scleral tissue of the eye. The one or more scleral prostheses are configured to modify a structure of the eye to improve an accommodative ability of the eye with the intraocular lens.

Patent number: 7591849Abstract: A multi-component accommodating intraocular lens (A-IOL) for implantation in a capsular bag of an eye having an optical axis, includes an anterior optical element and a posterior component that are connected by at least one compressible haptic. The compressible haptic, by definition, has a deformation feature that is resiliently deformable. The deformation feature allows the nominal overall diameter of the A-IOL to dynamically vary over a selected range in response to a capsular bag dimension that is different than that of an average population value, or in response to a change in the size and/or shape of the capsular bag due to post-operative capsular bag shrinkage, without substantially changing the separation distance between the anterior and posterior components of the A-IOL absent an intended accommodating force. Methods are also disclosed.Type: GrantFiled: July 1, 2005Date of Patent: September 22, 2009Assignee: Bausch & Lomb IncorpotedInventor: Gary A. Richardson
