PropertyValue
?:definition
  • Surgical punches designed to excise a segment of eye tissue (frequently in the form of a disc) or from grafts taken from donors. These punches are typically handheld, manual instruments with a sharp, hollow tip at the distal end or a rotary mechanism that may be integral or attached and operated by squeezing a two-part handle. Eye surgical punches are used mainly for ophthalmic graft implantation and to open a hole in the trabecular meshwork; they are less frequently used to obtain grafts from the sclera of cadaver donors.
