A method for preparing an ophthalmic device for slowing, inhibiting or preventing myopia progression involves (a) soaking an ophthalmic device in one or more first solvent solutions to swell the ophthalmic device; (b) soaking the swelled ophthalmic device in one or more second solvents solutions comprising one or more red-light blocking compounds blocking greater than about 5% to about 25% of red-light transmission through the ophthalmic device at a wavelength of from about 550 nanometers (nm) to about 800 nm to de-swell the swelled ophthalmic device and entrap the one or more red-light blocking compounds in the de-swelled ophthalmic device; and (c) sterilizing the de-swelled ophthalmic device.

Ophthalmic devices

An ophthalmic device for slowing, inhibiting or preventing myopia progression which is a polymerization product of a monomeric mixture comprising (a) greater than 50 wt. %, based on the total weight of the monomeric mixture, of one or more non-silicone-containing hydrophilic monomers; (b) one or more crosslinking agents; and (c) one or more red-light blocking compounds blocking greater than 5% to about 25% of red-light transmission through the ophthalmic device at a wavelength of from about 550 nm to about 800 nm, wherein the one or more red-light blocking compounds have one or more ethylenically unsaturated reactive end groups.

Method and apparatus for molding an IOL comprising first and second mold halves each having an optic forming surface and haptic forming surfaces which together define a mold cavity in the shape of the IOL to be molded therein when the mold halves are assembled together. An injection port is formed and connects to one of said haptic forming surfaces or the optic forming surface wherethrough a polymerizable material is injected into the mold cavity. A venting port is formed and connects to another haptic wherethrough air escapes from the mold cavity as the polymerizable material is injected through the injection port.

Apparatus and method for making intraocular lenses

A method for obtaining contact lenses having optimized visual acuity involves providing the anterior surface or the posterior surface of the contact lens with a conic section having a shape factor value within the range of about 0.3 to 2.0, the shape factor value being selected so as to adjust spherical aberration in the central optical zone to a value within the range of about &minus;0.2 diopter to about &minus;0.6 diopter and to a value that provides optimal visual acuity.

Contact lenses providing improved visual acuity

A method and apparatus for practicing the method of making toric contact lenses having a toric axis and ballast axis located on the anterior and posterior surfaces of a lens. Detectable features are formed on the anterior and posterior mold sections corresponding to the location of the toric axis and ballast axis, respectively. An axis alignment tool having detecting means thereon is used to set the mold sections to a known angular position. The desired axial offset is input into a computer which establishes the axial offset between the mold sections.

Toric axis alignment machine and method

A method for obtaining contact lenses having optimized visual acuity involves providing the anterior surface or the posterior surface of the contact lens with a conic section having a shape factor value within the range of about 0.3 to 2.0, the shape factor value being selected so as to adjust spherical aberration in the central optical zone to a value within the range of about -0.2 diopter to about -0.6 diopter and to a value that provides optimal visual acuity.
