Nanotechnology in Ophthalmology

Abstract

Despite various attempts, the delivery of ocular drugs appears to be a problem for pharmacologists. Most eye diseases are treated with topical applications of the drugs. But this does suffer from low bioavailability and other drawbacks. In recent years, Burgeoning interest in nano pharmaceutical products has produced several advances with a focus on engineering novel applications. Nanotechnology also provides disease detection capabilities at much earlier levels. Recent advances in research into the eye drug delivery system have provided important insights into developing drugs. Now we are looking at the recent discoveries and applications in ocular drug delivery of various nanosystems such as nanosuspensions, nanospheres, liposomes, and microemulsions.
