What's the difference between i.e. and e.g.?
abnormal position of the crystalline lens of the eye. The dislocation, which may be congenital, developmental, or acquired (typically via trauma), is usually caused by abnormalities of or injury to a portion of the suspensory ligaments (called zonular fibres) that anchor the lens to the ciliary muscle. Problems associated with lens dislocation include monocular double vision, decreased vision, and astigmatism
