What is Uniocular cataract?

For the purpose of this discussion a monocular cataract will be defined as advanced opacification of the crystalline lens in one eye, while the other lens is clear or has opacities that have not yet affected visual acuity.

What is pseudo aphakia?

A congenital condition in which the crystalline lens has degenerated and been replaced by mesodermal tissue.

What is monocular aphakia?

Aphakia is a condition that involves not having an eye lens. The lens of your eye is a clear, flexible structure that allows your eye to focus. This condition is most common in adults with cataracts, but it can also affect infants and children.

What is a vitrectomy surgery?

A vitrectomy is a type of eye surgery to treat various problems with the retina and vitreous. During the surgery, your surgeon removes the vitreous and replaces it with another solution. The vitreous is a gel-like substance that fills the middle portion of your eye.

What is Uniocular diplopia?

Binocular diplopia occurs when both eyes are open and resolves when either eye is closed. It is caused by a misalignment of the eyes, also called strabismus. Conditions that affect the cranial nerves supplying the muscles that control the eyes can cause binocular diplopia.

What is brown cataract?

A brunescent, or brown, cataract is often correlated with the maturity of a cataract and can cause decreased visual acuity. Brunescent cataracts can cause poor contrast and color discrimination, especially at the blue end of the visible light spectrum.

How long do eye lens implants last?

Unlike natural lenses, IOLs do not break down over a person’s lifetime and do not need to be replaced. It is possible to exchange implants if necessary.

Can I join the military with a cataract?

Army: Cataracts are considered disqualifying in AR 40-501 Standards of Medical Fitness. They are discussed in the Cataract Aeromedical Policy Letter which articulates similar aeromedical concerns as the USAF.

What is congenital aphakia?

Congenital primary aphakia (CPA) is a rare eye condition that is present at birth in which the lens is missing. In some cases, CPA can be associated with other eye abnormalities including microphthalmia, absence of the iris, anterior segment aplasia, and/or sclerocornea (when the cornea blends with the sclera).

What is Pseudophakia of both eyes?

What are the signs and symptoms of aphakia?

This can produce other symptoms, such as: blurry vision. trouble focusing on objects. changes in color vision, which involves colors appearing faded. trouble focusing on an object as your distance from it changes. farsightedness, or trouble seeing things up close.

What is an external optical correction for aphakia?

EXTERNAL OPTICAL CORRECTION. An aphakic eye, especially in children, has optical properties which are different from normal phakic eyes. Nowadays optical correction of aphakia in children includes aphakic glasses, aphakic contact lenses (CLs) and primary or secondary IOL implantation each having specific advantages and disadvantages.

Can a baby be born with aphakia without lenses?

Babies with primary congenital aphakia are born without lenses, usually due to developmental issues or a genetic mutation. Babies with secondary congenital aphakia have a lens, but it’s either absorbed or detached before or during birth.

When can babies with aphakia have eye surgery?

The American Academy of Pediatrics recommends that babies with aphakia have surgery when they’re about a month old. They’ll need glasses or special contact lenses that they can sleep in and wear for long periods of time after surgery.
