摘要： An apparatus and method for the production of ophthalmic lenses, and particularly contact lenses, which minimizes damage of the lens in removal from the mold. The ophthalmic lens is produced in a mold having a male part and a female part that are placed in proximate relation to each other to create a lens-forming cavity. At least the female surface of the female part mold is preferably coated with plasma and is irradiated for a predetermined time such that the female surface and/or surface coating is at least partially cured. Once the female surface, and alternately the male surface and other surfaces of the mold, is at least partially cured, a curable lens-forming material is placed into the lens-forming cavity and cured to form an ophthalmic lens.

摘要： In a process for removing bubbles from viscous polymer solutions (P) in which the content of dissolved gases lies below the saturation limit, the viscous polymer solution (P) is subjected to a superatmospheric pressure. The superatmospheric pressure is such that the gases contained in the bubbles of the polymer solution (P) dissolve.

摘要： A method of incorporating radiation-absorbing agents (i.e., dyes) into polymeric materials. A preferred method involves crosslinking or polymerizing a polymerizable or crosslinkable material in the presence of a polymeric dye. A preferred product is a tinted contact lens comprising poly(vinyl alcohol). The methods offer advantages in reduced fabrication cycles, reduced extractables, elimination of post-polymerization activation steps, elimination of post-polymerization extraction steps and reduced scrap and costs associated with lens handling.

摘要： The blister pack comprises a base portion and a cover layer. The base portion comprises a hollow chamber that contains a soft hydrophilic contact lens and a sterile aqueous preserving solution, and a substantially flat flange that extends right round the outside of the hollow chamber. The cover layer is releasably sealed to the flange in a sealing zone that extends right round the circumference of the hollow chamber. The flange comprises a grip region that extends from one side of the hollow chamber beyond the sealing zone and is covered by a corresponding grip region of the cover layer but is not sealed thereto. The hollow chamber comprises a dish-shaped main chamber and, adjoining the side of that main chamber, a secondary chamber in the shape of a channel tapering on all sides away from the main chamber, the main chamber making a smooth transition into the secondary chamber, and the main chamber and the secondary chamber together having a drop-shaped contour in the plane of the flange, the tip of which contour is directed towards the grip region of the flange. Provided in the grip region of the flange is an oval opening by means of which the overlying grip region of the cover layer can be lifted from the flange. A support element that is angled with respect to the plane of the flange is arranged in the grip region of the flange. An angled grip element or facilitating the handling of the blister pack is arranged at the edge of the flange on both sides of the hollow chamber. The base portion is so shaped that the blister packs can be nested in pairs with their undersides one inside the other, in each case the hollow chamber of one blister pack lying in the region of the grip region of the other blister pack. The blister pack is extremely handy, space-saving and stable, requires only an extremely small amount of preserving solution and enables the contact lens it contains to be removed especially easily.

摘要： The instant invention pertains to a method and a fluid composition for producing contact lenses with improved lens quality and with increased product yield. The method of the invention involves adding a phospholipid into a fluid composition including a lens-forming material in an amount sufficient to reduce an averaged mold separation force by at least about 40% in comparison with that without the phospholipids.
