Dry eye syndrome is a common disease of tear film and ocular surface developed in numerous aetiologies. Tear film instability and ocular surface disturbances that subsequently influence the tear film are among the primarily causes of this disease, but many other factors are involved in tear film disorders. Although eye surface is easily reached by classical ocular dosage forms, novel drug delivery systems for ocular administration offer advantages in terms of increased residence time on eye surface and/or controlled release of the drug, with enhanced therapeutic effectiveness. This book provides an overview on the potential benefits and limitations in dry eye syndrome management and reported successful formulations.
