Aphakia is the medical term used to describe the absence of the lens from an eye.


The lens may be missing for various reasons, e.g. surgical removal (as may be performed during cateract surgery), a perforating wound or ulcer, or it may be congenital (that is the condition present at birth).

Treatments for aphakia may involve the prescription and use of spectacles or contact lenses or by implant of an artificial lens (pseudophakia).
