Abstract: The fixation members of an anterior chamber intraocular lens (IOL) are provided with indicators for aiding the sizing and placement of the IOL. In one embodiment, the indicators are lines, dots or other contrast based indicia formed at a predetermined distance away from the distal tips of the fixation members. In another embodiment, the indicators are colored zones extending a predetermined distance radially inwardly from the distal tips. The predetermined distance is selected such that the indicators are visible at the edge of a patient's cornea, even though the distal tips of the haptic members are hidden behind the scleral rim. The surgeon can evaluate whether the IOL is centered by checking that the indicators are symmetrical relative one another. Similarly, the surgeon can tell whether the IOL is properly sized by determining the distance between each line, or the edge of each colored zone, and the edge of the scleral rim, and comparing this distance to a desired value.

Abstract: Disclosed is a method for producing an intraocular lens including an optic and at least one haptic. In one embodiment, the method comprises: exposing the lens bonding region of the haptic to a plasma at conditions effective to enhance the bondability of the lens bonding region to the optic; and bonding the exposed lens bonding region to an optic. The plasma exposed haptic may be coated with a material, e.g., to preserve the enhanced bondability property, prior to bonding the coated lens bonding portion to the optic. Intraocular lenses having enhanced haptic-optic bonding are also disclosed.

Abstract: Lenses and methods of lens attachment are disclosed which provide for highly effective, e.g., secure, attachment of the lens to the patient's cornea. Lenses are configured which are particularly adapted to be overlaid with corneal tissue to protect the lenses from forces parallel to the radial axis of the lens and generally parallel to the anterior surface of the lens optic.

Abstract: A system useful for holding a lens device is disclosed and comprises: a chamber having a hollow interior space therein; a seal element capable of being placed in association with said chamber to substantially seal said interior space from the environment surrounding said chamber; a carrier assembly sized and adapted to carry a lens device and to be placed in said interior space; and an absorbent member located in said interior space and capable of carrying a material which is released into said interior space over a period of time.

Abstract: An intraocular lens comprising a deformable optic and first and second fixation members. Each of the fixation members has a proximal end portion. First and second elongated anchors are coupled to the proximal end portions of the fixation members, respectively, and the anchors and the proximal end portions are within peripheral regions of the optic so that the anchors can assist in attaching the fixation members to the optic. The anchors are spaced apart so that the deformable optic can be folded to facilitate insertion of the optic through a relatively small incision into the eye.

Abstract: A method of treating an intraocular lens or ophthalmic surgical tool with a water-soluble adherent film forming material, such as polyvinyl alcohol, in a liquid media after which the liquid media is evaporatively removed to provide a dehydrated coating that is both water-soluble and liquid swellable. The device is packaged and sterilized, such as by ethylene oxide, and supplied to the ophthalmologist. Immediately prior to its use in surgery, the ophthalmologist rehydrates the coating by submerging in a sterile aqueous bath causing the coating to swell into a soft sluffable cushion for protecting a corneal endothelium during both static touch contact and dynamic sliding contact with the coated lens or tool.

Abstract: An intraocular lens or surgical tool used for eye surgery which is covered with a biocompatible water-soluble adherent film coating that has a very slow dissolution rate which maintains at least 40% of the coating on the lens for at least 30 minutes, but not more than 24 hours, when submerged in an aqueous media simulating the surgical environment. Polyvinyl alcohol is an example of such coating that is dissolvable in water and provides swellable outer portions of the coating that are sluffable so as to be self-sacrificing in protecting against both static and sliding contact with a corneal endothelium.
