Contact Lens Abstract
A contact lens container includes a body defining a cavity that is sized to hold a contact lens. A stopper is in fluid communication with the cavity and the stopper includes a resealable portion that is received into a channel. The resealable portion has a predetermined wall thickness in an axial direction thereof, the resealable portion defines a needle penetration region that is pierceable with a needle to form a needle aperture therethrough, and is heat resealable to hermetically seal the needle aperture.

Contact lens carrying case
Contact Lens Abstract
A disposable-type carrying case wherein the parts that house contact lenses cannot be re-sealed is realized via an easy-to-use construction.In the case main unit 10B of a contact lens carrying case 10, when a handle 12 that is integrally formed with a cover unit 20B is rotated in the clockwise direction, end portions 27G and 27H that are integrally formed with the handle 12 are gradually lifted up starting with the parts thereof that are near the handle 12 while engaging members 40G and 40H are fixed in position. When this occurs, first bridges 29G and 29H that are connected to end portions 27G and 27H are strongly pulled in the direction of rotation of the handle 12 while maintaining connection to top portions 41G and 41H. As a result, the first bridges 29G and 29H are sheared off from the end portions 27G and 27H and the engaging portions 40G and 40H detach from the cover unit 20B.

Contact lens package
Contact Lens Abstract
A blister package housing a contact lens is described. The package generally includes a base member including a cavity having a bottom surface, for containing a contact lens immersed in a liquid medium. The base member can include a grip region including a curved top surface shaped to accommodate a thumb and a curved bottom surface shaped to accommodate an inner curve of a forefinger. Silicone hydrogel contact lenses located in the liquid medium have a reduced tendency to stick to the bottom surface of the cavity without requiring a surfactant and/or a surface modification of the bottom surface.

Colored contact lens with a more natural appearance
Contact Lens Abstract
A colored contact lens (10) having a non-opaque pupil section (20), an iris section (22) surrounding the pupil section (20), and a colored, opaque intermittent pattern made up of a plurality of elements located over the entire iris section (22) that leaves a substantial portion within the interstices of the pattern non-opaque, the pattern covering an effective amount of the iris section (22) to change the apparent color of the iris, the pattern having a plurality of portions, each of the portions being a different shade from each other portion, each of the portions overlapping each other portion at a plurality of points, thereby providing a lens (10) capable of changing the apparent color of the iris of a person wearing the lens (10) and imparting a very natural appearance.

Panretinal laser fundus contact lens
Contact Lens Abstract
An optical lens system is designed to speed and improve therapeutic laser irradiation of the inner eye. The device is housed in an external casing (10) in conjunction with a specialized fundus contact lens (22). Internally, a disc (12) is mounted with a rotary central mirror driven by a micromotor (14). Toward the periphery of the plate a ring of mirrors is arranged (20). Below the mounted disc lies an additional set of mirrors (24) set at inclinations to divert incident energy to the posterior segment of the eye. As incoming laser energy (28) strikes the central mirror it diverts the beam to a peripheral mirror which again deflects the light to another mirror at the posterior end of the device. A control box (30) facilitates coordinating laser bursts with the circumferential motion of the central mirror. The apparatus results in a ring of laser delivered to the internal eye.

Hydrodynamically operated multifocal contact lens
Contact Lens Abstract
This invention pertains to a soft contact lens that has a body with a central zone aligned with the optical axis of the eye when a wearer wears the lens. A micro-channel filled with fluid, is positioned at or near the optic zone and is arranged so that when the fluid is pressurized, the micro-channel expands and changes the optical characteristics of the central zone. The pressure in the microchannel is controlled through changes to a reservoir disposed in the lens below the optic zone.

Contact lens blister packages and methods for automated inspection of hydrated contact lenses
Contact Lens Abstract
A contact lens package includes a base member including a cavity dimensioned to accommodate contact lens and a liquid therein. The combination of the cavity, the contact lens, and the liquid cooperate to collimate partially collimated light directed toward a bottom surface of the cavity. The cavity can be sealed by attaching a removable sealing member to the base member around the cavity. Methods of inspecting ophthalmic lenses using the present packages are also described.

Liquid diagnostic contact lens
Contact Lens Abstract
A liquid diagnostic contact lens includes a main body having a concave lens, and a supporting element disposed at a bottom of the main body. A heavy fluid is placed on a top surface of the concave lens. A transparent plate is sealed over the top surface of the concave lens so as to define an encapsulating room and encapsulate the heavy fluid therein. In operation, an ophthalmologist places the supporting element onto the eye, and examines various interior spots of the eye by adaptively adjusting the eye. The liquid diagnostic contact lens is tilted along with the eye and the top surface of the heavy fluid is kept horizontal so the heavy fluid is formed as prisms of different diopters. Thus, the liquid diagnostic contact lens can examine various spots of the interior of the eye.

Contact lens manipulation and cleaning apparatus
Contact Lens Abstract
The present invention provides apparatus for manipulating and cleaning of contact lenses, together with methods for same. The apparatus comprises at least one eyepiece, at least one body and a cleaning housing. The at least one eyepiece is attached to the at least one body and defines an opening in the body. The at least one eyepiece comprises a head for engaging a contact lens and an eyelid opening mechanism. The at least one body includes a contact tens manipulation device. The apparatus is arranged such that when the at least one eyepiece is attached to the body and the face of the user is in contact with the eyepiece, the eyelid opening mechanism engages the upper and lower eyelids to retain them open while a retractable mechanism removes the contact lens from the eye of the user. The cleaning housing is engageable with the eyepiece and can effectuate cleaning of the contact lens once removed from the eye of the user.
