A contact lens case includes a platform portion. The platform portion can include a receiving body, an inner wall formed in the receiving body, a floor connected to the inner wall, the inner wall and the floor defining a chamber, and a lens positioning guide formed in the floor of the chamber.

Contact lens case

A contact lens case including a container main body provided with a housing recess for storing a contact lens and a liquid agent, and a lid that is connected to the container main body via a hinge in a freely openable and closable manner. A lens holding body is displaceably housed in the housing recess, and by connecting the lid and the lens holding body via a connecting member, the lens holding body can undergo rising and falling displacement following open and close action of the lid around the hinge. A displacement restricting member is provided that restricts a direction of the rising and falling displacement of the lens holding body to the vertical direction that coincides with a depth direction of the housing recess.

A fastening device for a conveying cart is used for fastening the conveying cart to a to-be-fastened apparatus. The device includes a flange provided on a side of the to-be-fastened apparatus, and having a pin standing therefrom, and a recess formed therein; and a fastening mechanism provided on a side of the conveying cart, and having a first hook member engaging with the pin of the flange so as to position the conveying cart with respect to the to-be-fastened apparatus, and a second hook member engaging with the recess of the flange so the to fasten the conveying cart to the to-be-fastened apparatus.

A method of molding an ophthalmic lens product by using a mold assembly which has a mold cavity, the lens product having a configuration corresponding to that of an ophthalmic lens or a precursor of the ophthalmic lens and being obtained by polymerizing a liquid monomer composition in the mold cavity to provide a polymer product which gives the lens product, the method comprising the steps of: preparing the mold assembly having a monomer storage space for storing the liquid monomer composition, which storage space is held in fluid communication with the mold cavity; filling the mold cavity of the mold assembly with the liquid monomer composition while the liquid monomer composition is accommodated in the monomer storage space; and polymerizing the liquid monomer composition at a temperature of 10-80&deg; C. while a pressure higher than the atmospheric pressure is applied directly to a liquid surface of a mass of the liquid monomer composition accommodated in the monomer storage space.

An intraocular lens of one-piece body consisting of supporting portions 34 and an optical portion 32 is formed by forming an annular supporting-portion-forming blank 2 composed of a polymerization product for supporting portion 34, which has a thickness to form the supporting portion 34 for an intraocular lens and has a through hole 4 formed by concentrically drilling the central portion on the basis of the outer diameter of the blank; forming a composite-lens-forming blank 24 by filling in the through hole a monomer composition 16 for forming another polymerization product 22 for the optical portion followed by polymerizing it whereby the polymerization product 22 is formed integrally in the through hole; and processing the blank 24 on the basis of its outer diameter.

Method for producing an intraocular lens

A balloon for an intraocular lens, which is a unitary elastic hollow body made of an elastomer and having a convex lenticular shape without projections along its circumference, which gives, when inserted in a lens capsule, a configuration corresponding substantially to the shape of the lens capsule, said hollow body having a wall thickness of from 0.001 to 0.1 mm at its optical portion and a diameter of from 6 to 13 mm, and capable of being inflated in the lens capsule to form an intraocular lens when a light transmitting injection material is injected into the hollow body.
