摘要:
Lacrimal inserts such as punctal plugs may be utilized for delivery of medication to the eye. The plug includes a body portion sized to pass through a lacrimal punctum and be positioned within a lacrimal canaliculus of the eyelid. The plug may contain a core, or reservoir, at least partially within the body portion comprising a therapeutic agent that is configured for controlled, pulsatile release into the eye.

A lacrimal insert such as a punctal plug may incorporate a balloon or other similar structure to facilitate anchoring of the punctal plug within the lacrimal canaliculus. The balloon may be inflated once it is positioned and deflated if removal is required or desired. The balloon may be affixed to an external portion of the punctal plug or incorporated into a chamber within the punctal plug.

摘要:
This invention provides a mold comprising a first mold half which works in conjunction with a second mold half for forming ophthalmic devices wherein said first mold half comprises at least one changeable cassette comprising inserts for forming said ophthalmic devices. The mold is particularly well-suited for use in an injection molding machine.
摘要:
This invention relates to a device for removing and transporting articles, such as ophthalmic lens mold sections, or packaging elements from a mold. The invention, in one embodiment includes first, second, and third assemblies; the first of which removes the articles from the molding station at a first location and transports them to a second location; the second assembly receives the articles from the first assembly and transports them to a third location, and the third assembly receives the articles from the second assembly and transports them to a fourth location. A second embodiment includes a flipper assembly disposed between the first and second assemblies, which flipper receives the articles from the first assembly and inverts them before depositing them onto the second assembly. This second embodiment is useful in conjunction with molded articles which are transported to the flipper assembly in an inverted position. A third embodiment includes second and third assemblies which further include means for altering the relative spacing of the articles while the articles are transported.
