How to Use

Proper Sizing: Determine the proper plug size prior to optional dilation. Start with the smallest gauge size (.5 mm). Gently insert the head of the gauge into the punctum, being careful not to go beyond the neck. When entering and leaving the punctal opening, the gauge head should slightly flex the punctal ring. If there is no resistance to the gauge, the next larger size should be tried. The gauge size is too large if there is substantial resistance and the tip is difficult to insert. The proper plug size is found when the punctal opening flexes moderately when the gauge is inserted and removed and the gauge tip is “snug” when in the punctum. In some patients, the left and right eyes may have different size punctum, therefore it is useful that the punctum of both eyes are measured.
