The word-stem "cantho-" refers to the canthus, which is the corner of the eye (strictly the angle at which the upper- and lower- eyelids meet). It is useful to recognise this terminology as used to refer to procedures concerning the corner(s) of the eye(s).
A cantholysis is a surgical procedure in which the attachment of the canthus (corner of the eye) is separated / divided from the underlying tendon, tendon being in turn attached to bone.
A cantholysis is not a stand-alone procedure but is carried-out as a part of some delicate operations on the eyelid (see related term blepharoplasty).
