Sterile strips have a printed mm scale for easy test interpretation. These strips have smooth, rounded tips. The strips are individually packaged in an easy-to-open 'band-aid' wrapper.
Instructions: Do not apply any topical medication to the eye or perform any manipulation of the eye before performing this test. Position patient in examining chair with head against a headrest. Examination room lights should be dimmed. Carefully open strips according to directions shown on the box. While patient looks up, insert the rounded end into the lower temporal lid margin of the eye, making sure the strip fits snugly.
