What is Aphakia?

Aphakia (pronounced “uh-FAY-kee-uh”) means that you're missing the lens in your eye. The lens sits behind your pupil and iris, which is the colored part of your eye. Your iris is protected by the clear cornea and is surrounded by the sclera (the white part of your eye).

  • Blurred vision.
  • Problems seeing things that are close and far away.
  • Problems seeing the brightness of colors. Colors may seem to be faded.
  • An iris that jiggles. This is called iridodonesis.
  • Problems adjusting to differences in how far away or close something is

Open-angle or angle-closure glaucoma is a possible complication of cataract removal and pediatric aphakia. This type of glaucoma is called aphakic glaucoma. Children who have cataract surgery will need to wear bifocal glasses even if they have implanted lenses or aphakic contact lenses.

  • Cataract surgery. A cataract is clouding of the eye's natural lens. With surgery, the cataract is removed.
  • Injury. The lens can be damaged or lost due to eye trauma.
  • Congenital defect. Very rarely babies are born without lenses. Others are born with detached or abnormal lenses.

Aphakic glaucoma. If a person has surgery to treat aphakia, one of the risks is aphakic glaucoma, a condition in which pressure inside the eye builds up to the point that it damages the optic nerve. Untreated glaucoma can lead to vision loss. Retinal detachment.
