<p>An ophthalmic device (10, 31, 50, 81) in the form of a cup (11, 31, 51) having a periphery (12, 32, 52, 85) substantially scaphoid in plan for contacting a facial region in the vicinity of an eye. The interior of the cup is accessible from its exterior by way of at least a first port (14, 34, 58, 86) and a second port (15, 35, 60, 87). The first port (14, 34, 58, 86) provides an inlet for a dispensing unit (17, 38, 63) for material to be supplied to the eye. The second port (15, 35, 60, 87) provides a target for viewing by an eye about which the periphery (12, 32, 52, 85) is disposed. The device (10, 30, 50, 81) is preferably fabricated from a material which is substantially opaque or imperfectly transparent and the second port (15, 35, 60, 87) is an aperture which provides a viewing target for an eye with which the device is being used. Alternatively the device can be in the form of a transparent shell with a distinctive target supported on the shell. A projection (16) can be located on the device (10, 30, 50, 81) outside the periphery (12, 32, 52, 85) to form an initial contact point for the device (10, 30, 50, 81) on a facial region in the vicinity of an eye. The projection (16) serves to enhance contact with, and displacement of, a displacable surface in the region of the eye on which it is located on movement of the device (10, 30, 50, 81) relative to the eye.</p> |
