New drug delivery system in ophthalmology: results studying the surface structure of soft contact lenses from various polymer

The development of an ophthalmic therapeutic system includes research on the spatial structure soft contact lens polymers and study processes saturation release medicinal substances from them. This allows you to determine methods lenses with agents will open up new opportunities in treatment ophthalmological diseases. purpose this preliminary fragment large-scale was surface made various polymers. following were used work: Nelfilcon A, Hilafilcon B, Nezofilcon Etafilcon Lotrafilcon B. pharmaceutical used: Brimonidine Tartrate, Betaxolol Hydrochloride, Pyridoxine Hydrochloride. studied using atomic force microscopy. Each material under has a different character, which together differences pore properties determines its individuality. Based this, it should be assumed that affects possibility their potential use as means delivering drug agent molecules eye tissues. In all cases saturation, highest absorption capacity demonstrated by B A similar surface.
