Aphakia - Eye defect
Aphakia is rare eye defect that is defined by the absence of an eye lens. This condition may either be congenital or due to injury or cataract surgery, during which the lens must be removed from the eye. Without the focusing power of the lens, the eye becomes very farsighted, it is therefore necessary to use a correction. Contact lenses or intraocular lenses (surgically implanted in the eye) are primarily used to treat aphakia.
