Abstract

An amniotic membrane perforator tool having a tip portion, a shaft portion, a flexing portion, and a handle portion. The shaft portion is adjacent the tip portion and is preferably of a generally T-shaped cross-section having a vertical component and a horizontal component. The shaft portion is intermediate the tip portion and the flexing portion. The flexing portion is intermediate the shaft portion and the handle portion, and includes at least one crest and at least one valley. The shaft portion is pivotable at the flexing portion relative to the handle portion. The handle portion is dimensioned such that the handle portion is wider than high. Furthermore, the handle portion preferably includes a plurality of ribs.
