A homemade corneal marker was contrived from a Pharmacia Superblade disposable corneal trephine by cutting away one arm of the trephine and then bending the single remaining arm to an angle of 45 degrees to the handle. The radii of the trephines ranged from 6.5mm to 8.5mm, at successive increments of 0.25mm. In optical corneal grafts, this marker can be used to pinpoint the center of the cornea, thus providing more accurate centralization of the area to be grafted. In therapeutic corneal grafts, the marker provides a more accurate determination of the most suitable area to be grafted. Unnecessary removal of healthy tissue or incomplete removal of diseased tissue are thus avoided. This marker is made easily and at no additional expense, and show itself to be a useful instrument to accurately determine the graft area in corneal surgery.
一种自制角膜标记器是由法玛西亚一次性角膜环钻改制而成，具体方法是将环钻的一个臂切除，然后将剩下的单个臂弯曲至与手柄呈45度角。环钻的半径范围为6.5毫米至8.5毫米，以0.25毫米的连续增量递增。在光学角膜移植中，这种标记器可用于确定角膜中心，从而更准确地确定移植区域的中心位置。在治疗性角膜移植中，该标记器能更准确地确定最合适的移植区域。这样就避免了不必要地切除健康组织或未完全切除病变组织的情况。这种标记器制作简便且无需额外费用，是角膜手术中准确确定移植区域的有用工具。
