Latest Patents

Shinzo Ohkada holds a patent for producing soft contact lenses. The patent describes a method that involves pouring an excess amount of an original solution for producing a soft contact lens into a concave mold. A convex mold is then placed on the concave mold, allowing the excess solution to overflow and uniformly fill the space between the two molds. The original solution is gelled between the molds to form a lens with a tensile strength of at least about 0.1 kgf/cm². The lens is then immersed in a liquid to facilitate peeling it from the molds, followed by an extraction treatment with water. This innovative process improves the manufacturing of soft contact lenses, making them more accessible and effective for users.
