An ophthalmic formulation is provided for the prevention and treatment of adverse ocular conditions, including presbyopia, arcus senilis, age-related macular degeneration, and other conditions associated with aging. The formulation is also useful in the prevention and treatment of other adverse ocular conditions such as those associated with oxidative and/or free radical damage within the eye; these conditions can involve a condition, disease, or disorder of the cornea, retina, lens, sclera, anterior segment, or posterior segment of the eye. In one embodiment, the formulation contains at least 0.6 wt. % of a biocompatible chelating agent, an effective permeation enhancing amount of an ophthalmic permeation enhancer such as methylsulfonylmethane (MSM), an anti-AGE agent, i.e., a compound that serves to reduce the presence of advanced glycation endproducts (AGEs) in the eye, and a pharmaceutically acceptable ophthalmic carrier suited to the particular formulation type (e.g., eye drops or ointments). In another embodiment, the formulation contains an ophthalmologically active agent and MSM as a penetration enhancer. |
