• We describe a new instrument specifically designed to perform a "wedge" punctoplasty. The Reiss punctal punch was designed to be an enhancement of the one-snip punctoplasty by providing greater uniformity and improved tear access to the punctum via an excised posterior tissue wedge as well as inhibiting reapproximation of the cut edges leading to recurrent punctal stenosis.
