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

Abstract:
The present invention provides a method for treating a contact lens to provide an optically clear, hydrophilic coating upon the surface of a silicone hydrogel lens by subjecting the surface of the lens to a process comprising plasma treatment, hydration, and heat sterilization that is controlled to result in a silicate-containing film having a mosaic pattern of projecting plates surrounded by fissures when viewing a 50×50 micron square AFM image, wherein the peak-to-valley distances of the fissures are on average between about 100 and 500 angströms and the plate coverage is on average between about 40% to 99%.

Abstract:
An inspection system includes an inspection station configured to receive a plurality of ophthalmic devices, and a fluid supply fluidly connected to the inspection station. The fluid supply contains a working fluid. The system also includes an ultrasonic degassing assembly configured to remove at least one bubble carried by the plurality of ophthalmic devices upstream of a packaging station.
An apparatus and method for inverting a plurality of contact lenses between separate processing steps which treat the opposite concave and convex surfaces of the lenses. The lenses are initially placed convex side-up on a perforated lens support surface and are subjected to the first processing step which treats this surface of the lens. The support surface is then passed over an elongated air stream which traverses and is directed to impinge upon the bottom surface of the support whereby the air stream passes through the perforations in the support and inverts the lenses from the convex side-up position to a concave side-up position whereupon this surface of the lenses may be treated in a subsequent processing step.

Abstract:
The present invention provides an optically clear, hydrophilic coating upon the surface of a silicone hydrogel lens by subjecting the surface of the lens to a process comprising plasma treatment, hydration, and heat sterilization that is controlled to result in a silicate-containing film having a mosaic pattern of projecting plates surrounded by fissures when viewing a 50. times. 50 micron square AFM image, wherein the peak-to-valley distances of the fissures are on average between about 100 and 500 angstroms and the plate coverage is on average between about 40% to 99%.
A contact lens package includes a base including an upper surface and a receptacle having a volume. The contact lens package also includes a flexible cover including an interior surface that is coupled to the upper surface of the base. A stiff dome is attached to an interior surface of the cover and the stiff dome displaces an amount of volume from the volume of the receptacle. The contact lens package may also include a lens having an anterior surface and a posterior surface disposed in the receptacle with the posterior surface of the lens disposed adjacent to the stiff dome. By peeling the flexible cover away from the base, the lens remains mounted on the stiff dome causing the anterior surface of the lens to be presented to a user.
