  • Publication number: 20240041907
    Abstract: Polymeric compositions are provided that include a poly(ethylene glycol), a viscoelastic polymer, and an antioxidant, where, in polymerized form, the compositions have a refractive index of about 1.30 to about 1.40. Methods of synthesizing the compositions are also provided and include the steps of heating an amount of water, adding a buffering agent to the water to form a buffer solution; mixing a poly(ethylene glycol) and a viscoelastic polymer into the buffer solution to form a reactive mixture; adding a plurality of antioxidant particles to the reactive mixture; and removing suspended gas bubbles from the reactive mixture. Methods of preventing oxidative damage to an eye lens of a subject are further provided and include administering the foregoing polymeric compositions to the eye lens of the subject.

  • Publication number: 20230046275
    Abstract: Methods of reducing oxidative damage to an eye of a subject are provided. Aspects of the method include intravitreal injection an antioxidant composition consisting essentially of a non-reducing sugar or a hydrate thereof. In some embodiments, the non-reducing sugar is trehalose. The methods can further include surgical removal of at least a portion of the subject's vitreous humor during a vitrectomy. Also provided are ophthalmic compositions, kits and pre-loaded injection devices for use in vitrectomy surgery which find use in the subject methods.
