AI Technical Summary

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 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 diopt...

Abstract

Intraocular lenses and related assemblies and intraocular attachment methods are disclosed herein. In one embodiment, an intraocular lens assembly comprises a helical-shaped coil fastener to affix anintraocular lens to an iris to correct for astigmatism, presbyopia, and / or myopia or hyperopia. The helical-shaped coil fastener comprises a head and a helical wire extending from a bottom surface ofthe head and comprising a pointed tip opposite the head. The helical-shaped coil fastener is configured to be affixed to the iris by rotatable penetration of the iris, and thus can be removed from theiris by reverse rotation of the helical-shaped coil fastener. The helical-shaped coil fastener has a low volume, large surface area, low cross-sectional area of penetration, and an oblique angle of penetration. Thus, the helical-shaped coil fastener is easy to apply, easy to remove, minimizes tissue damage, maximizes stability, and minimizes penetration force.

Description

[0001] priority application [0002] This application claims the benefit under 35 U.S.C. 119(e) of a patent application entitled "Apparatus and Methods for Refractive Intraocular Implant System," filed August 14, 2015. 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, among others. However, these alternatives are not without drawbacks and deficiencies. For example, LASIK surgery has limited corrective powe...
