Abstract: A container (10) has a base (12) on a cap (14). The container (10) has a chamber (38) for liquid. The base (12) on the cap (14) are arranged to be interengaged so as to seal hermetically the chamber (38). The base (12) and the cap (14) have multi-sided portions which interengaged to form the hermetic seal. The cap (14) has outwardly flared sides so that as the cap (14) is rotated relative to the base (12) the cap is caused to move out of the base and the hermetic seal is broken so that the contents of the chamber (38) may be accessed.

Abstract: A liquid container (10) has a base (12) and a cap (14) which interengage to form a hermetically sealed chamber (42). The cap (14) has a curved outer wall (18) and the base has a curved inner wall (36). The outer and inner walls (18, 36) have perspective non-circular portions and are of complementary shape. The cap (14) is able to be rotated axially relative to the base (12) by means of a handle (24) so that the outer and inner curved walls (18, 36) interact such that the cap (14) is released from the base (12) upon axial rotation thereof and the hermetic seal is broken.

Abstract: A liquid container (10) has a base portion (12) and a cap portion (14) which are engaged with one another for relative slidable linear movement. The cap has an upwardly facing recess (29). Initially, the cap portion (12) and the base portion (13) define a hermetically sealed chamber (42) containing a liquid (40). Upon relative movement of the cap portion (14) and the base portion (12), the base enters the chamber (42) and the hermetic seal is broken so that the liquid (40) is urged into the recess (29) of the cap portion (14).

Abstract: A method of preparing intraocular lenses in situ is disclosed. The method involves the injection of an unsaturated macromonomer of Formula I: The macromonomer is then polymerized to give a polymer suitable for use in an intraocular lens.

Abstract: A hydrophilic ethylenically unsaturated macromonomer is disclosed that is prepared by the addition polymerization of addition polymerizable monomers that include monomers that have hydroxyl or amino functional groups, some of which may be subsequently reacted to provide (meth)acryl ethylenic unsaturation. The macromonomers may be used to form intraocular lenses in situ by polymerization of the macromonomers, and thus treat presbyopia.
