Patent number: 7462194Abstract: A multi-part IOL which is insertable through an opening as small as about 1 mm without deforming the haptic, is described. This IOL may be used in the anterior chamber of the eye for phakic or aphakic lenses. After insertion of the haptic into the eye, any type of lens may be attached, especially by use of cleats. The haptic is a high modulus skeletal frame, and may be assembled with lower modulus material. An eyelet may be provided on the lens allowing a cleat on the haptic to firmly attach to the optic.Type: GrantFiled: August 4, 2000Date of Patent: December 9, 2008Inventor: Larry W. Blake

Patent number: 7192444Abstract: An aspheric soft intraocular lens, having an optical power surface, which may have multiple radii portions or aspherical portions, as well as spherical portions, intended to replace the crystalline lens of a patient's eye, in particular after a cataract extraction. Such an aspheric soft lens is molded in a coined mold. A pair of core pins, positioned within the mold cavity during the lens forming process, will produce a pair of haptic-mounting holes within the lens. As the lenses are subsequently tumbled to remove flash, indentations will form adjacent to the haptic-mounting holes. These indentations allow for tangential attachment of the haptic to the lens which, in turn, enables maximum flexibility without exceeding the width of the optic.Type: GrantFiled: May 24, 2002Date of Patent: March 20, 2007Assignee: Advanced Medical Optics, Inc.Inventors: Larry W. Blake, Lee T. Nordan

Patent number: 6605093Abstract: This invention discloses devices for use with an ophthalmologic insertor apparatus. In one embodiment, the device is a flexible, stretchable sleeve holder adapted to fit over a deformable sleeve that houses an implant. The sleeve holder facilitates loading of an implant into the sleeve by providing a suitable gripping surface. Application of a compressive force to the sleeve holder further allows the implant to be immobilized within the sleeve. After loading of the implant into the sleeve, the holder may be used as a collar or hub to secure the sleeve to an insertor hand-piece. Methods for loading implants into delivery sleeves, methods for attaching sleeves to inserters, and methods for delivering implants to an incision are also disclosed.Type: GrantFiled: January 5, 2000Date of Patent: August 12, 2003Assignee: Tekia, Inc.Inventor: Larry W.

Patent number: 6425917Abstract: A film frame for an IOL has been developed which has the advantages of being lightweight, non-irritating, easily surgically implanted, aesthetically pleasing, and containing plate haptics. This IOL works in the anterior or posterior chamber of the eye for phakic or aphakic lenses and especially in the anterior chamber for phakic refractive lenses where thinner is better and long-term stability is required. This deformable IOL frame is a haptic system based on a high modulus harder material shaped skeletal frame or plate haptic assembled with low modulus softer elastomeric hinged zones. The rigid frame or haptic in combination with the soft hinges will ensure that the lens is ideally situated in the anterior chamber angle of the eye. Additionally, the soft elastomer can be extended to provide for a softer atraumatic contact point or ‘toe’ in the eye tissue.Type: GrantFiled: May 12, 2000Date of Patent: July 30, 2002Assignee: TekiaInventor: Larry W.

Patent number: 5772667Abstract: An intraocular lens injector compresses an intraocular lens by rolling the lens into a tight spiral and injects the compressed lens though a relatively small incision in the eye, approximately 2-3 millimeters in length, resulting from a phacoemulsification procedure. The intraocular lens is inserted into a receiving channel of the injector in an uncompressed state and is urged into a cylindrical passageway. As the intraocular lens advances into the cylindrical passageway, the lens will roll upon itself into a tightly rolled spiral within the confines of the cylindrical passageway. An insertion rod is inserted into an open end of the cylindrical passageway and advances the compressed lens down the passageway. As the lens exits the passageway and enters the eye, the lens will expand back to its uncompressed state.Type: GrantFiled: November 14, 1996Date of Patent: June 30, 1998Assignee: Pharmacia Iovision, Inc.Inventor: Larry W.
