Problems solved by technology

As a result, many current IOL procedures are difficult to insert and attach, require large incisions in the cornea for surgical access, are difficult to remove, and / or cause complications due to aggravated and damaged iris tissue and / or loss of corneal endothelial cells

Embodiment Construction

[0069] Embodiments disclosed herein include intraocular lenses (IOLs) and related components and implants and intraocular attachment methods. In some aspects, a helical coil fastener and associated applicator tool and surgical insertion method are provided to attach the IOL to the iris relative to the pupil. In one embodiment, the IOL assembly includes a helical coil fastener to attach the IOL to the iris to correct astigmatism, presbyopia, and / or nearsightedness or hyperopia. An IOL can be implanted to correct vision errors with the patient's natural lens removed or left in place. The IOL can be used as a phakic implant (eg, for use with a phakic) or as an aphakic implant (eg, for use without a phakic). The IOL has optics to correct for astigmatism and / or optical effects of nearsightedness or hyperopia (eg, a first optical effect). The IOL may also have another optical effect (e.g., a second optical effect) to address presbyopia (e.g., as a phakic IOL that works up to 2.0 d...

Abstract

Intraocular lenses and related components and methods of intraocular attachment are disclosed herein. In one embodiment, the intraocular lens assembly includes a helical coil fastener to attach the intraocular lens to the iris to correct astigmatism, presbyopia, and / or nearsightedness or hyperopia. A helical coil fastener includes a head and a helix extending from a bottom surface of the head and including a pointed end opposite the head. The helical coil fastener is configured to be attached to the iris by rotatably penetrating the iris, and thus can be removed from the iris by counter-rotation of the helical coil fastener. Helical coil fasteners have small volume, large surface area, small penetration cross-sectional area and penetration angle. Thus, helical coil fasteners are easy to apply, easy to remove, minimize tissue damage, maximize stability, and minimize penetration forces.

Description

[0001] priority application [0002] This application claims benefit under 35 U.S.C. 119(e) to a patent application filed on August 14, 2015 entitled "Apparatus and Methods for Refractive Intraocular Implant System" (Apparatus and Methods for Refractive Intraocular Implant System) 62 / 205,226, the content of which is relied upon and incorporated herein by reference in its entirety. technical field [0003] The field of the disclosure relates generally to devices and methods for intraocular attachment systems, and more particularly to implant designs, surgical methods, tools, and fasteners for attaching intraocular implants to the iris. Background technique [0004] Patients and surgeons have long been interested in alternatives to eyeglasses that compensate for eye abnormalities. These alternatives include, for example, contact lenses, radial keratotomy, LASIK or laser vision correction surgery. However, these alternatives are not without drawbacks and deficiencies. For e...
