Using a motorized blade known as a keratome, Seedor cut a circular flap around the cornea, about one-third of an inch wide and one-150th of an inch thick, and peeled it back.

During surgery, the flap-cutting keratome might jam or create a wrinkle in the cornea, in perhaps one in 500 eyes, said Dr . Jonathan Carr, director of medical services for the Lasik Vision chain.

Unlike keratome-and-scissors incision, a well-performed von Graefe knife maneuver produced a corneal or limbal incision with well-opposed edges that resulted in rapid healing and a scar that was almost invisible to the naked eye.

In the 1980s, with the ever-increasing popularity of the Kelman phacoemulsification technique that emphasized a small incision and extra-capsular cataract extraction ( ECCE ), the keratome-and-scissors, large incision surgery technique combined with intracapsular cataract extraction ( ICCE ) became obsolete, although the use of the von Graefe knife still continued in India.
