Embodiment Construction

[0062] Once the natural lens has been surgically removed, the haptic device is used to attach the intraocular lens within the lens capsule. The three specific design goals of the haptics are: i) to allow the lens to be implanted in the eye through an incision of less than about 3mm, by means of a specialized syringe; ii) to allow the lens to move in the posterior chamber of the eye, so that the Provides focus flexibility; and iii) minimizes posterior capsule opacification ("PCO") by attaching the lens to the equator of the lens capsule, a side effect of lens replacement surgery that typically occurs 2-3 postoperatively. Occurs in approximately 50% of patients within a year. Although current IOLs have been successfully implanted for decades, many haptic designs have not yielded the desired reduction in PCO and / or facilitated focus flexibility (or patient adjustment from farsightedness to nearsightedness and minimized exposure to reading glasses). required capabilities).

Abstract

The present invention relates to a haptic for fixation to and manufactured with an intraocular lens so as to be embedded within the natural lens capsule of the human eye. The haptics hold the lens in place within the natural capsule such that better visual acuity is provided through the aphakic lens. The tip of the haptic is designed to position the lens naturally in the middle, anterior or posterior of the lens capsule. At the point of attachment of the ribbon to the solid end plate of the haptic, the haptic may be notched to facilitate pressing the lens into its syringe for insertion into the eye through an opening in the cornea. Once compressed and passed through the cornea, the implanted lens is secured by haptics within the lens capsule from which all possible natural lens material and epithelial cells have been removed.

Description

[0001] Refer to related applications [0002] This application claims the equally titled U.S. Provisional Application 61 / 118,085, filed November 26, 2008, and the equally titled U.S. Provisional Application 61 / 157,781, filed March 5, 2009, and Priority to similarly titled U.S. Provisional Application 61 / 184,655, filed on , the entire contents of each of which are hereby incorporated by reference. technical field [0003] The present invention relates to a haptic device for an intraocular lens that provides enhanced comfort and performance for the patient. In particular, the present invention relates to haptic devices and designs including injectors for inserting intraocular lenses without turning the lens, and to methods for performing the inserts. In particular, the present invention and its various iterations are designed, when used with single vision lenses, to provide an appropriate degree of focus flexibility or accommodation and, in certain circumstances, to reduce the ...
