  • Patent number: 11931291
    Abstract: A first sponge device for use to manipulate and prepare the surface of the epithelium of an eye prior to application of an ophthalmic solution has a handle and a sponge head secured to the handle. The head is made of an absorbent, wicking sponge material and has a non-sharp, tissue preparation surface of predetermined shape for rubbing across the surface of the epithelium layer in order to manipulate the tissue. After the surface is prepared, a second, holding sponge is placed over the eye to act as a reservoir and to hold ophthalmic solution against the eye surface.

  • Publication number: 20230285451
    Abstract: Methods and compositions for treating various indications by lessening oxidative stress in a patient are provided. A pharmaceutical composition comprises between about 0.001% to about 10.0%, or more specifically between about 0.015% to about 5%, sodium iodide or catalase by weight. The iodine ion or the catalase dissociates hydrogen peroxide into water and molecular oxygen to interrupt biological events that result in negative side effects. The pharmaceutical composition further comprises in some cases a reducing agent or various carrier materials. The pharmaceutical composition is in some cases formulated for a variety of delivery methods.

  • Publication number: 20220211542
    Abstract: Ophthalmic treatment systems and methods of using the systems are disclosed. The ophthalmic treatment systems include (a) a light source device; (b) at least one optical treatment head operatively coupled to the light source device, comprising a light source array, and providing at least one treatment light; and (c) a light control device, which (i) provides patterned or discontinuous treatment light projection onto an eye (e.g., the cornea and/or sclera of an eye); or (ii) adjusts intensity of part or all of the light source array, providing adjusted intensity treatment light projection onto an eye (e.g., the cornea and/or sclera of an eye). The at least one treatment light promotes corneal and/or scleral collagen cross-linking.
