Nanoparticles are solid colloidal particles ranging in size from 10-1000 nm. They can be used as drug carrier with the drug encapsulated, dissolved, adsorbed or covalently attached. Nanoparticles are able to interact and remain associated to the ocular mucosa for extended periods of time, thus being promising carriers for enhancing and controlling the release of drugs to the ocular surface. Current studies are aimed at investigating in further detail how the interaction and internalization of these particles occurs and their toxicity following repeated administration. With breakthroughs in...

Nanoparticles are solid colloidal particles ranging in size from 10-1000 nm. There are material used for preparation of nanoparticle, but most commonly they are polymers such as poly-alkylcyanoacrylate, polymethylmethacrylate, polybutylcyanoacryalate, or are albumin or gelatin. The substantial value that ophthalmic interventions confer to patients with eye diseases has led to intense research efforts in this area in recent years, with corresponding improvements in treatment, ophthalmic instrumentation and surgical techniques. As a result, the future for ophthalmology holds great promise as...
