  • Publication number: 20250018666
    Abstract: Provided is a method for manufacturing photoabsorbing contact lenses and photoabsorbing contact lenses produced thereby. The method comprises: (a) providing a mold assembly comprised of a base curve and a front curve, the base curve and the front curve defining and enclosing a cavity therebetween, the cavity containing a reactive mixture, wherein the reactive mixture comprises at least one polymerizable monomer, a photoinitiator which absorbs at an activating wavelength, and a photoabsorbing compound which displays absorption at the activating wavelength; and (b) curing the reactive mixture to form the photoabsorbing contact lens by exposing the reactive mixture to radiation that includes the activating wavelength, wherein the radiation is directed at both the base curve and the front curve of the mold assembly, and wherein the radiation's radiant energy at the base curve is greater than the radiation's radiant energy at the front curve.

  • Patent number: 7723387
    Abstract: A dermatologic peel comprising alpha hydroxyl acid and metal hydroxide nanocomplexes as neutralizing agents to continually reduce the activity of the system when the acid and neutralizer components are mixed. For example, a 30% glycolic acid gel mixed with a fluidized magaldrate neutralizer can be applied to the skin and will self-neutralize to a skin-compatible pH within a few minutes, effectively exfoliating the skin without a separate neutralization step. The peel is advantageously applied from a two-component system that mixes the components.

  • Patent number: 7156641
    Abstract: This invention provides a mold for forming a contact lens comprising an overflow collector, which causes the overflow reactive mixture to be accumulated, and not to spread out as it would upon the typically flat surface of a prior art mold. This invention further provides a method of preventing the formation of contaminating pieces of overflow reactive mixture comprising the step of: preventing the overflow reactive mixture from spreading out on the mold.
