Iridodonesis () is the vibration or agitated motion of the iris with eye movement. This may be caused by lens subluxation, the incomplete or partial dislocation of the lens; or by aphakia, the absence of a lens. The term originated from irido- (Latin: iris) + doneo (Greek: δονεο, to shake to and fro). See also
Phacodonesis
