Azaam Alli has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 11958923
    Abstract: Disclosed are co-polymers which are produced from reactive monomer mixtures and which have both high refractive index and a high Abbe number. These materials are well suited for use as implantable ophthalmic devices and have a refractive index which may be edited through application of energy. When used for an intraocular lens, the high refractive index allows for a thin lens which compresses to allow a small incision size.

  • Patent number: 11945180
    Abstract: The present invention relates to a method of manufacturing a contact lens including the steps of: (i) adding reactive components to a mold, wherein the reactive components comprise (a) at least one hydroxy-containing silicone component having a weight average molecular weight from about 200 to about 15,000 g/mole and (b) at least one mono-ether terminated, mono-methacrylate terminated polyethylene glycol having a weight average molecular weight from about 200 to about 10,000 g/mole; (ii) curing the reactive components within the mold to form the contact lens; and (iii) removing the contact lens from said mold.

  • Publication number: 20230416470
    Abstract: Described is a silicone hydrogel contact lens having non-uniform morphology. The contact lens may be made from a reactive mixture comprising: a silicone-containing component; a hydrophilic component; a non-reactive polymeric internal wetting agent; and a polymerization initiator, the contact lens having an oxygen permeability of at least about 60 barrers, and wherein the molar ratio in the lens of the polymeric non-reactive internal wetting agent to silicone, without a surface treatment, is greater in the lens's surface than in its bulk.

  • Patent number: 11828913
    Abstract: Described are silicone hydrogels that are more biocompatible than current ocular materials. The silicone hydrogels are formed from a reactive monomer mixture comprising: a mixture of hydroxyl substituted silicone containing components, at least one polyamide; and at least one hydrophilic monomer. The silicone hydrogels also display a desirable balance of properties, including clarity, oxygen permeability, wettability and desirable protein uptake.

  • Patent number: 11829008
    Abstract: A molded contact lens comprising a stiffer optic zone relative to the peripheral zone of the contact lens provides an optical element for correcting astigmatism without the need for or substantially minimizing the need for the correction of rotational misalignment. The higher elastic modulus optic zone vaults over the cornea thereby allowing a tear lens to form. The tear lens follows or assumes the shape of the back surface of the contact lens. The combination of the tear lens and the optical zone provide an optical element for correction of refractive error.
