Rapid exchange iol insertion apparatus and methods of using
A system for easily transferring an intraocular lens (IOL) from a lens case to an inserter, and then into a patient's eye. The lens case has a transfer mechanism therein which retains the IOL until engagement with the inserter. The transfer mechanism may include jaws having a closed configuration for retaining the IOL and an open configuration for releasing the IOL. Engagement of the inserter with the lens case automatically opens the jaws and transfers the IOL to the inserter. The IOL is transferred into a load chamber of a nosepiece rotatably coupled to a handpiece. After transfer of the IOL, the nosepiece is rotated from a load position to a delivery position. The IOL may have an optic and a haptic coupled to the optic, and the lens case may be capable of configuring the haptic as desired to facilitate its transfer into an inserter and / or into the eye. For instance, the lens case may fold one or both of the haptics over the optic. Preferably, the lens case maintains the haptic in this position during transfer of the intraocular lens into an inserter and / or inserter cartridge. A manifold for easily distributing a viscoelastic medium to the load chamber of the inserter is also provided.

Intraocular lens and method for preventing secondary opacification
InactiveUS6027531APrevent proliferationImprove stabilityDiagnosticsSurgeryCataract extractionPosterior capsulorhexis
An intraocular lens for use in extracapsular cataract extraction has a haptic pat that surrounds the optical pat of the lens and further contains a groove of such shape to accommodate the anterior and posterior capsules of the lens bag after anterior capsulorhexis, extracapsular cataract extraction and posterior capsulorhexis. The lens is preferably inserted in a calibrated, circular and continuous combined anterior and posterior capsulorhexis, slightly smaller than the inner circumference of the groove as to induce a stretching of the rims of the capsular openings. This new approach is believed to prevent the appearance of secondary opacification of the capsules, allows a very stable fixation of the intraocular lens and ensures a tight separation between the anterior and posterior segment of the eye. This new principle of insertion is called the bag-in-the-lens technique, in contrast with the classical lens in-the-bag technique.

ActiveUS6923539B2Add depthSolve lack of contrastIntraocular lensOptical partsIntraocular pressureImage resolution
The present invention provides monofocal ophthalmic lenses that exhibit extended depth of field while providing sufficient contrast for resolution of an image over a selected range of defocus distances. In some embodiments, a lens of the invention can include a refractive surface having controlled surface modulations relative to a base profile. The surface modulations are designed to extend a depth of field of the lens such that a single image can be resolved, albeit with somewhat less contrast, over a range of distances greater than the focal region of a conventional lens. The ophthalmic lenses of the invention can be employed in various vision correction applications, including, but not limited to, intraocular lenses, contact lenses, instrastromal implants and other refractive devices.

Accommodating intraocular lens system with aberration-enhanced performance
An accommodating intraocular lens implantable in an eye. The lens comprises an anterior portion having an anterior biasing element and an anterior optic having refractive power. The lens further comprises a posterior portion having a posterior biasing element and a posterior optic having refractive power. The anterior optic and the posterior optic are relatively moveable in response to action of the ciliary muscle to change the separation between the optics and the refractive power of the lens. The lens has an aberration-inducing force characteristic of about 70 mg to about 115 mg to allow aberration-inducing relative movement of the optics when the lens is in the eye, thereby adding optical aberration to the lens which increases depth of focus of the lens. In one variation, the lens has an aberration-inducing force characteristic of 70 mg to 115 mg. Related methods are also disclosed.
