Abstract:
1. A guide for use with a needle to prevent damage to a patient's eye when the needle is injected into the patient's eye, the guide comprising: a shield having an inner contour that conforms to the exterior of the patient's eye, at least partially beyond its cornea, when the shield is positioned on the front of the patient's eye; a guide aperture extending through the shield, the guide aperture being configured so that the needle can be inserted through the guide aperture and into the patient's eye, wherein the guide aperture extends through a cylindrical member extending beyond an exterior surface of the shield to provide an internal guiding surface having a length greater than the thickness of portions of the shield spaced from the cylindrical member; and a visibly alignable alignment member on the shield, the alignment member being configured so that the shield can be visibly aligned relative to the cornea of the patient's eye and the guide aperture can be positioned relative to the eye so that the needle will not damage the patient's eye when the alignment member is visibly aligned with the cornea.
