An apparatus (1;2) for removing an ophthalmic lens from a mold half (3;4), comprises a ring member (10;20) movable towards and away from the mold half (3;4), the ring member (10;20) comprising a central opening (103;203) and a plurality of nozzles (100;200) circumferentially distributed about the ring member (10;20), each nozzle (100;200) having an outlet opening directed towards the mold half (3,4) as the ring member (10;20) is placed on the mold half (3;4), and a gripper member (11;21) arranged to be movable towards and away from the mold half (3:4) through the central opening (103;203) of the ring member (10;20).

A tubing and junction assembly and method of making the same are disclosed. The assembly includes a shell having a bore extending from a first opening to a second opening, and a third opening extending from an exterior surface of the shell to a first end portion of the bore. A tubing is seated within the bore. A bonding agent is disposed between the tubing and the shell. The method of making the tubing and junction assembly includes forming or providing a shell, inserting an end of the tubing through the first opening into the shell, inserting a bonding agent through the third opening of the shell into a gap between the tubing and the shell, and curing the bonding agent to join the tubing to the shell.

An acoustic lens for an ultrasonic probe includes a vulcanization-molded article of a rubber composition including a first silicone rubber composition having a plasticity number of 100 or less, and a second silicone rubber composition having a plasticity number of 150 or more and 300 or less.

Solution casting a nanostructure. Preparing a template by ablating nanoholes in a substrate using single-femtosecond laser machining. Replicating the nanoholes by applying a solution of a polymer and a solvent into the template. After the solvent has substantially dissipated, removing the replica from the substrate.

The invention is related to contact lenses that not only comprise the much desired water gradient structural configurations, but also have a minimized uptakes of polycationic antimicrobials and a long-lasting surface hydrophilicity and wettability even after going through a 30-days lens care regime. Because of the water gradient structural configuration and a relatively-thick, extremely-soft and water-rich hydrogel surface layer, a contact lens of the invention can provide superior wearing comfort. Further, a contact lens of the invention is compatible with multipurpose lens care solutions present in the market and can endure the harsh lens care handling conditions (e.g., digital rubbings, accidental inversion of contact lenses, etc.) encountered in a daily lens care regime. As such, they are suitable to be used as weekly- or monthly-disposable water gradient contact lenses.

The invention provides a contact lens manufacturing method comprising a process for removing unprocessed molded silicone hydrogel contact lenses from mold halves in a relatively efficient and consistent manner. A method of the invention comprising the steps of formulating a lens formulation by dissolving/blending all polymerizable components in a mixture a hydrophobic acrylic monomer as a reactive diluent and an organic solvent as a non-reactive diluent at a weight ratio of least 0.24 (reactive diluent over the sum of reactive and non-reactive solvents) per gram of the polymerizable composition and using a relatively low ultrasonic vibration energy for delensing. This method of the invention can be easily implemented in a production environment for enhancing the production yield.

A method for manufacturing a silicone hydrogel contact lens is described that comprises curing a polymerizable composition comprising at least one siloxane monomer and at least one hydrophilic vinyl-containing monomer in a contact lens mold comprising a molding surface having a coating comprising a hydrophilic polymer. The hydrophilic coating is not solubilized by the polymerizable composition during the curing step. The resulting polymeric lens body is removed from the mold, washed to remove any of the hydrophilic polymer that may have transferred from the mold surface to the lens during the curing or lens removal process, and packaged to provide a silicone hydrogel contact lens having a contact angle that is lower than what it would otherwise be had the lens been cured in the same contact lens mold lacking the hydrophilic coating.

A preparation method of a bionic adhesive material with a tip-expanded microstructural array includes the following steps: machining through-holes on a metal sheet; modifying morphology of a through-hole by electroplating, using the metal sheet in step 1 as an electroplating cathode, and arranging the electroplating cathode and an electroplating anode in parallel to prepare a hyperboloid-like through-hole array assembly, fitting a lower surface of the hyperboloid-like through-hole array assembly tightly to an upper surface of a substrate assembly to prepare a through-hole assembly of a mold; and filling the mold assembly with a polymer, curing, and demolding to obtain the adhesive material with the tip-expanded microstructural array.

A medical device including a pre-defined space such as a geometric shape or void. In one approach, the pre-defined space provides desired rigidity and more comfort for a user. There is also provided an approach which enables engravings and accommodates electronics, mechanical objects, or other rigid or unique shapes to be embedded within a medical device such as a contact lens. When adapted to swellable substrates, the resulting swelled material can leave a gap around a perimeter of embedded structure.
