aphakia

Absence of the internal crystalline lens of the eye. Aphakia results either from surgical removal or from penetrating injury, which may be followed by absorption. An aphakic eye is severely out of focus and requires a powerful lens for clear vision. Such a lens may be provided as a contact lens, so as to avoid the undue magnification and distortion of glasses. In some cases a lens implant within the eye may be considered feasible.

aphakia 

Ocular condition in which the crystalline lens is absent. It may be congenital but usually it is due to surgical removal of a cataract. As a result the eye has no accommodative power and is usually highly hyperopic. See aniseikonia; cataract; pseudophakic eye; aphakic lens; phakic; jack-in-the-box phenomenon; vitreous detachment.
