Contact Lens Abstract
Contact lenses ready for use in an eye are provided including a contact lens body containing a hydrophilic polymeric component and a water soluble polymer component. Such contact lenses, which preferably are wet cast molded, are particularly useful as disposable or single use lenses. New contact lens packaging systems and production methods are also provided.

Contact lens storage container with needle penetrable and laser resealable stopper, and related method
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.

Methods for designing tinted contact lenses
Contact Lens Abstract
The invention provides methods for designing patterns for use in tinted contact lenses in which the patterns are generated using algorithms. The method of the invention provides an objective description of the pattern for purposes of tooling, metrology and manufacturing of a lens incorporating the pattern.

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.

Soft contact lenses displaying superior on-eye comfort
Contact Lens Abstract
The present invention relates to soft contact lenses having an overall comfort preference of at least about 2 to 1 as compared to an Acuvue.RTM. contact lens and measured after one week of daily wear. The present invention further relates to a soft contact lens comprising an oxygen transmissibility greater than about 70 barrers/mm and physical properties suitable to provide wearer comfort over at least about 9 hours in at least about 80% of wearers, as measured in a randomized, double masked clinical study.

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.

Method for designing multifocal contact lenses
Contact Lens Abstract
The invention provides methods for designing contact lenses that takes into account pupil size and vergence. The lenses of the invention augment the eye’s accommodative gain and take advantage of the eye’s residual accommodation amplitude.
