Abstract
A cannula may include a tubular section having a distal end, a proximal end, and forming a passage, and an elastomeric membrane coupled to and encircling the tubular section. The cannula may also include a valve that is movable between an open condition and a closed condition to selectively provide access to the passage defined by the tubular section. When the tubular section is inserted into an eye during an ophthalmic surgery, a concave surface of the elastomeric membrane acts as a suction cup to retain the cannula device onto a surface of an eye.
