title: A new microsurgical corneal trephine.
abstract: A new corneal trephine has been described which allows the surgeon to see the circumference of the cutting edge, as well as most of the cornea, lens and iris, while looking through the operating microscope. The trephine has a 3-mm cutting ring supported by an open "branding iron" structure.
