ABSTRACT:
An ophthalmic instrument for removing foreign objects from an ocular surface includes a multi-purpose tool head attached at an angle to the end of a handle. The generally flat tool head includes a main body and an upwardly angled distal tip. A pair of side scoops are arranged on the sides of the main body, and an omnidirectional plane is arranged between the side scoops. A V-shaped notch with a sharply beveled front edge is arranged on one side of the main body. The upturned distal tip is usable for prying out partially embedded objects. The V-shaped notch is usable for securely engaging both sides of an object and gently rocking it loose. The side scoops and the plane are usable for scooping or rocking loose objects. A graduated scale is provided on the tool head for measuring the size of the foreign objects. Accordingly, the present ophthalmic instrument provides several tools for removing foreign objects of different sizes, shapes, and consistencies. Additionally, the tool head is made of an optically clear plastic, so that it does not obscure the surgical field.
