ABSTRACT:
A marking device is provided for marking the sclera and/or limbus of a patient's eye to standardize and define incision location and suture placement prior to cataract removal, and to aid in the intraoperative control of astigmatism. The device comprises a generally arcuate body member having opposed major surfaces with a plurality of projections extending from one of the major surfaces. The body member has an inferior arc and a superior arc with the inferior arc having a smaller radius than the superior arc. The projections are radially aligned, extending from the major surface and are adapted to be inked and to transfer ink marks to the sclera and/or limbal area of an eye. The ink marks represent the locations where incisions and sutures are to be placed.
