Contact lens package

A method and apparatus for transferring a wet object, such as a contact lens, from a first station to a second station includes a probe having a barrel with a passage for communication with a vacuum source and a pressurized gas source, a nozzle at the end of the passage, and a hood around the nozzle in communication with a vacuum source. The barrel is moved in a first direction to place the nozzle adjacent the object in the first station and the vacuum from the nozzle attaches the object to the nozzle. Moving the barrel in a second direction removes the nozzle with the object attached from the first station. The probe is moved to the second station with the object attached. The barrel is moved in the first direction to place the object at the second station, the vacuum is removed from the nozzle and pressurized gas is applied through the barrel passage to remove the object from the nozzle and deposit it at the second station and, at the same time, blow off matter from the object. Vacuum is applied to the hood when the probe is at the second station for the hood to collect the matter blown the object by the compressed gas.

Contact lens transfer and material removal system

An apparatus is provided for removing and transporting articles, such as contact lens sections from a manufacturing line to inspection and packaging stations. The lenses are deposited in a transparent plastic primary package which carries the lenses through the inspection station and becomes part of the primary package when a cover is sealed thereto. The invention includes various assemblies, including lens transfer assemblies, deionized water filling and removal assemblies, a water degassing assembly, a lens inspection assembly, and a lens package sealing assembly. The lenses are removed from pallets at a post hydration station, transported and spatially redistributed, and deposited in the primary packages disposed on a second set of pallets. The packages on the second set of pallets are filled with degassed deionized water. The contact lenses and packages are then transported to an inspection station. After inspection, the lenses and packages are transported to a water removal assembly, and then to another transfer assembly. This transfer assembly separates those lenses which passed inspection from those which did not, and places those that did in a consolidating assembly. The lenses and packages are then filled with saline solution and a foil label is then sealed thereto to form the primary package.

This invention discloses an apparatus and method for hydrating or washing ophthalmic devices, comprising the step of directing to an ophthalmic device having a higher concentration of impurities fluid which has previously been directed to ophthalmic device having a lower concentration of impurities.

Method and apparatus for washing or hydration of ophthalmic devices

An automated means for hydrating and packaging a molded hydrophilic contact lens in one of the mold parts used to mold the lens is provided in which a first robotic assembly removes a plurality of contact lens molds from a production line carrier, each of the lens molds having a contact lens adhered therein. The first robotic assembly transports the molds to a first staging area where the lens molds are sandwiched between a lens mold carrier and a top chamber plate to form a first hydration carrier. The hydration carrier is then transported through a plurality of flushing or extraction stations wherein fresh deionized water is introduced into the hydration chambers at each hydration station to flush leachable substances from the hydration chamber. At each flushing station, fresh deionized water is introduced into the hydration chamber to remove previously extracted impurities and the products of hydrolysis. A final robotic dis-assembly device separates the top chamber plate and lens molds in the mold carrier plate, to provide fully hydrated lenses in a concave lens mold ready for transfer to inspection and packaging stations. Following inspection of the lens, the concave lens mold is dosed with saline and used to form part of the package used to distribute the lens.

Automated method and apparatus for single sided hydration of soft

A method for removing a liquid from a container having a bowl and a flange, the bowl holding the liquid and containing a hydrophilic ophthalmic lens, wherein there is provided a nozzle with a central face and a shoulder around the periphery of the face. The shoulder has a sealing means which is sized to fit on the flange of the container, where it forms a sealed volume above the container bowl, this volume including the volume of the bowl itself. The central face has through it at least one fluid entrance passage and at least one fluid exit passage arranged so that the flow is distributed substantially symmetric about the center axis of the lens so that when the purging fluid is introduced into the sealed volume, there is no migration of the lens. There is connected to the entrance passage a source of purging fluid that has a pressure and flow sufficient to remove substantially all the liquid through the exit passage.

Method for removing a solution from a container package

An automated means for hydrating a molded hydrophilic contact lens is provided in which a first robotic assembly removes a plurality of contact lens molds from a production line carrier, each of the lens molds having a contact lens adhered therein. The first robotic assembly transports the molds to a first staging area where the lens molds are sandwiched between a lens mold carrier and a top chamber plate to form a first hydration carrier. A first rotary transfer device then hands the first hydration carrier to a second robotic assembly which immerses the first hydration carrier in a hydration bath to hydrate the lens and to release the lens from the lens mold. While the lens is immersed in the hydration bath, each lens is transferred from its respective mold to a lens transfer means found within the top chamber plate. After a predetermined period of time, the second robotic assembly removes the first hydration carrier from the hydration bath and hands the hydration carrier off to a second rotary transfer device which rotates the first hydration carrier and aligns it for transfer to a third robotic assembly. The third robotic assembly then carries the top chamber plate and contact lenses through a series of steps in which the lens mold carrier and lens molds are removed from the top chamber plate. The lenses carried on the lens transfer means are then flushed and transported for assembly with a hydration base member to form a second hydration carrier for processing the lens in subsequent extraction stations. The second hydration carrier is then transported through a plurality of flushing or extraction stations wherein fresh deionized water is introduced into the hydration chambers at each hydration station to flush leachable substances from the hydration chamber. At each flushing station, fresh deionized water is introduced into the hydration chamber to remove previously extracted impurities and the products of hydrolysis. A final robotic dis-assembly device separates the top chamber plate and lens transfer means from the hydration base member, to provide fully hydrated lenses in a concave lens holding means ready for transfer to inspection and packaging stations.

Automated apparatus for hydrating soft contact lenses

The present invention, which relates to the transfer of contact lenses in post hydration processing of the lenses. A lens transfer and insertion assembly removes contact lenses from lens hydration pallets, alters their spatial distribution, and deposits them into packaging elements. The lenses are transferred with fluid and retained on the transfer assembly by surface tension.
