Parts Of Visual System Affected

Aphakia (a-FAY-key-ah) is the term used to describe an eye that does not have a natural lens.


Aphakia is the absence of the lens of the eye, due to surgical removal, a perforating wound or ulcer, or congenital anomaly. It causes a loss of accommodation, hyperopia, and a deep anterior chamber. Complications include detachment of the vitreous or retina, and glaucoma. Aphakic people are reported to be able to see ultraviolet wavelengths that are normally excluded by the lens. This may have had an effect on the colors perceived by artist Claude Monet, who had cataract surgery in 1923.

Effects Of The Condition On Visual System

  • Rarely seen at birth

  • It most often seen as a result of surgery to remove congenital cataracts (clouding over the lens of the eye, which blocks light)

  • Congenital cataracts usually develop as a result of infection or as part of other conditions

  • The exact cause of these cataracts may be hard to figure out, especially if only one eye is affected

  • Congenital and stable



It is very important to remove the cataracts and treat the aphakia. Treatment for aphakia can include glasses, but contact lenses are often the best choice. These contacts lenses are safe for your baby to sleep in.

If the child has aphakia, other treatments may be needed in addition to wearing contact lenses. This might include using eye drops or an eye patch, or both. The goal is to make sure your child uses the eye with aphakia, so it does not become lazy. Aphakia is non-progressive and congenital.
How This May Affect Your Student At School
Students with Aphakia may suffer from peripheral field distortions, reduced visual acuity, and poor depth perception.

Common accommodations may include:

  • preferred seating

  • good visual contrast

  • avoid glare

  • extra time for refocusing

  • monocular cues for depth
