Apparatus and methods for injection molding intraocular lenses includes an embodiment having first and second runners extending into first and second optic cavities of a mold configured to make a dual optic lens device.

Method for injection molding an intraocular lens device

Apparatus and method for injection molding an intraocular lens device

The present invention provides a holder for supporting a two optic accommodating intraocular lens device. The holder is capable of holding the device while taking measurements or performing manufacturing process steps on the device and/or packaging the device. In a preferred embodiment, the holder supports the device along the haptics thereof such that the optics remain untouched and unobstructed by the holder. As such, testing and/or processing of the optics during their accommodative and unaccomodative positions may be taken, and the device may be safely packaged and shipped with the holder.

Universal accommodating IOL holder for lens processing and packaging

Intraocular lenses or contact lensesare placed on a lower spindleand held there by a vacuum in conduit. Noble and reactive gasesare introduced and a voltage is applied across upper spindleand lower spindleto plasma treat one surface of the lens. The lens is transferred to the other spindle and the process is repeated.

Plasma treatment of contact lens and IOL

An assembly for orienting and fixturing an array of contact lenses in a lens-fixturing tray to enable automated picking of the lenses includes an array of tubes to which a first support tray having an array of lens receptacles each having a respective contact lens therein is removably mounted. A lens-fixturing tray having an array of lens receptacles is removably mounted to the other end of the tubes and the assembly is rotated and submerged in a fluid bath whereby the lenses release from the first support tray and float downwardly through a respective tube coming to rest in a centered, concave side-up position in a respective receptacle of the lens-fixturing tray.

Handling assembly for fixturing ophthalmic lenses

Toric contact lenses are provided with markings that enable identification of the offset between the cylindrical axis of the toric zone and the ballast axis. Surfaces of the lenses include two markings, a first identifiable marking that is aligned with the cylindrical axis, and a second identifiable marking that is aligned with the ballast axis.

Toric contact lens markings

A method and apparatus for practicing the method of making toric contact lenses having a toric axis and ballast axis located on the anterior and posterior surfaces of a lens. Detectable features are formed on the anterior and posterior mold sections corresponding to the location of the toric axis and ballast axis, respectively. An axis alignment tool having detecting means thereon is used to set the mold sections to a known angular position. The desired axial offset is input into a computer which establishes the axial offset between the mold sections.

Toric axis alignment machine and method

Contact lenses include a posterior surface including a first identifiable marking, and an anterior surface includes a second identifiable marking different from the first marking, the first and second markings in combination designating the optical correction of the lenses. The lenses are useful in methods where the markings are used to identify characteristics of the lens.

Method for identifying characteristics of contact lenses

An improved method for forming plastic molds for casting articles having an optical surface such as contact lenses employs a plastic tool having an optically smooth surface.

Method of making plastic molds

Apparatus for making plastic molds

A mold assembly includes first and second mold sections having respective first and second mold cavity defining surfaces, the first mold cavity defining surface terminating in an encircling peripheral rim and the second mold cavity defining surface terminating in a deformable peripheral annulus disposed at a diameter corresponding to the rim, and cooperating tapers depending from each of the first and second molds for relatively centering the molds.
