1. A device for delivering an active agent to an eye of a subject, comprising:
- an ocular lens-shaped housing operable to contact a surface of the eye;
a reservoir coupled to the housing and operable to deliver an active agent into the eye, wherein the reservoir surface area configured to face the eye is less than about 50% of the surface area of the housing configured to face the eye; and
a vacuum device coupled to the housing and operable to create negative pressure between the housing and the surface of the eye.

13. A method for enhancing ocular delivery of an active agent to the eye of a subject, comprising:
-
contacting an ocular lens-shaped housing having a reservoir containing the active agent against an eye surface such that the reservoir contacts a delivery region of the eye, wherein the reservoir surface area configured to face the eye is less than about 50% of the surface area of the housing configured to face the eye; applying a vacuum between the housing and the eye surface sufficient to maintain the reservoir substantially in alignment with the delivery region during delivery of the active agent; delivering the active agent from the reservoir into the eye; and removing the housing from the eye. - View Dependent Claims (14, 15, 16, 17, 18)
