Cataract Contact
Lenses - Aphakia
Aphakia Defined
Aphakia is a
condition where the eye no longer has a lens to focus light on the
retina. There
are congenital conditions where from birth the lens in the eye does
not exist, but more commonly Aphakia is a result of a cataract
operation where the patient was unable to receive an intraocular
lens implant surgically. Aphakia can be similar to "High
Hyperopia" in contact lens fittings.
Correction of
Aphakia with Contact Lenses
The preferred method of correction of
Aphakia is contact lenses instead of eyeglasses. Many different contact lenses are
available including disposable contact lenses which are now
available as high as +20.00 diopter. Contact lenses can restore
vision with complete peripheral vision and little minification
error. Magnification error is when looking through a high plus prescription all images are
increased in size. This is especially difficult when only one eye is
Aphakic. Wearing eyeglasses would cause the Aphakic eye to have a much
larger magnified image compared to the normal eye. Contact lenses of the same
correction will allow images to have less magnification error.
