Sometimes, cataracts can cause double vision (also known as diplopia) when you look with 1 eye. This is different than the double vision that comes from the eyes not lining upwards properly, which would requite y'all double vision when looking out of both eyes together.

Cataract Symptom: Second Sight
Sometimes, a cataract may temporarily improve a person'southward ability to see close-upward, because the cataract acts as a stronger lens. This miracle is called second sight, considering people who may have once needed reading glasses find that they don't need them anymore. As the cataract worsens still, this goes away and vision worsens again.
Cataract Symptom: New Prescription
Frequent changes to your eyeglass or contact lens prescription can be a sign of cataracts. This is considering cataracts are ordinarily progressive, meaning they get worse over fourth dimension.
Who Gets Cataracts?
The majority of cataracts are related to crumbling. More than half of Americans over 65 accept cataracts. Babies are sometimes built-in with cataracts, besides called congenital cataracts, or children may develop them as a outcome of injury or illness. Exposure to Ultraviolet (UV) light can as well increase the risk of cataract and other heart conditions.
What Causes Cataracts?
The exact cause of cataracts is unknown. While the run a risk grows as you lot go older, these factors may too contribute:
- Diabetes
- Smoking
- Excess alcohol employ
- Eye Injury
- Prolonged apply of corticosteroids
- Prolonged exposure to sunlight or radiation
How Are Cataracts Diagnosed?
Most cataracts tin can be diagnosed with an eye exam. Your eye doctor volition test your vision and examine your eyes with a slit lamp microscope to look for problems with the lens and other parts of the eye. The pupils are dilated to amend examine the back of the eye, where the retina and optic nerve lie.
Surgery for Cataracts
If you have vision loss caused by cataracts that tin't be corrected with spectacles or contact lenses, you may need surgery to remove the cataracts. In cataract surgery, the cloudy lens is removed and replaced with an artificial lens. The surgery, which is done on an outpatient basis, is safe and extremely constructive at improving vision. If cataracts are present in both eyes, surgery will be done on one eye at a time.
Types of Cataract Surgery
There are 2 main types of cataract surgery. The more common type is called phacoemulsification (phaco) or "Ultrasonics." The medico makes a tiny incision in the eye and breaks up the lens using ultrasonic waves. The lens is removed, and an intraocular lens (IOL) is put in its place. In most modernistic cataract surgeries the IOL eliminates the demand for thick glasses or a contact lens after surgery.
Cataract Surgery Innovations
Recent developments in cataract surgery tin correct both nigh and altitude vision. They minimize or eliminate the need for reading glasses subsequently surgery. Conventional "monofocal" lenses only right for distance vision, pregnant reading glasses are all the same needed after surgery. Multifocal IOLs (Intraocular Lens) can be an option in some patients to help amend both distance and near vision. "Toric" implants are available to correct astigmatism. A lens for ameliorate color vision is in development (shown hither next to a dime).

Surgery slightly raises the take a chance of retinal disengagement, which requires emergency treatment. Sometimes, lens tissue left subsequently surgery and used to support the IOL can become cloudy, fifty-fifty years after surgery. This "after-cataract" is hands and permanently corrected with a light amplification by stimulated emission of radiation.
Should Yous Have Cataract Surgery?
