Even after stimulation of the erector papillae, the small size of the tip (0.4 mm) allows easy entry into the small aperture. The tip is approximately 1 mm in length, and the remainder of the probe is sufficient in size to dilate the punctum, although a separate dilator may be preferred. Early (1962) in the use of these probes, there was concern about the sharp points damaging the canaliculus. However, this has not been a problem in practice.
