Ophthalmic diseases present unique challenges to effective treatment. For instance, high degrees of physical dexterity and coordination are needed to apply ocular drops, which are sometimes uncomfortable once instilled and often expensive to purchase.
Treatments for the back of the eye require precise anatomic administration of an injection by a physician, which are frightening to patients, and frequency of these injections may include undesirable side effects and safety concerns.
All of these factors create a substantial healthcare burden for patients, caregivers, and physicians, and frequently lead to poor compliance or discontinuation of treatment.
Significant research and financial support has been dedicated to creating alternatives that will address these factors, and that will increase the quality of life and therapeutic effect in the ophthalmic realm.
