What is a cataract eyes: facts about cataracts

Worldwide, about 285 million people suffer from visual impairment

One third of all visual impairment in the world accounts for this disease.We deal with a specialist that is cataract eyes, how to get rid of, and how to prevent it.


In fact, it is a progressive clouding of the lens of the eye.The disease proceeds without pain, but it leads to a decrease in visual acuity and often even to its complete loss.

Most often, cataracts are found in older people, but can also occur in young people.


Blurry vision

Blurred vision at any distance is the most common symptom of a cataract.Vision may be blurred , there is a feeling of film covering the eye.Over time, the light gets smaller on the retina.Special vision problems may occur at night.

Light sensitivity

Another early symptom of cataracts is photosensitivity.In bright light, it may be difficult to focus your eyesight.Even artificial light sources that haven’t bothered you before can now seem too bright and annoying.Driving a car at night due to the bright light of lanterns or headlights of oncoming cars also becomes a problem.

Double eyes

Sometimes a cataract causes double vision.And double vision can even with one closed eye.

Change in color perception

Cataracts affect the perception of colors: some shades begin to appear faded, with time all the images become brown or yellowish.At first, these changes may go unnoticed , but over time it will become difficult for you to distinguish between shades of blue and violet.

“Second” vision

Sometimes a cataract causes a temporary improvement in vision.Under the influence of changes, the lens begins to act as a powerful magnifying glass – this phenomenon is called the second vision, because patients who used reading glasses suddenly realize that they do not need them.However, as the disease progresses, vision deteriorates again.

The need for new glasses

Due to frequent vision changes, patients with cataracts have to constantly change glasses or contact lenses.It’s all about the progressive nature of the disease.Vision continues to deteriorate.

How does a cataract affect your vision?

In normal vision, light penetrates and passes through the lens of the eye. The lens focuses this light in the form of a distinct image on the retina, which is transmitted through the optic nerve to the brain. If the lens is clouded due to a cataract, the image becomes fuzzy. Some other diseases of the eye, such as myopia, also cause blurred vision. But some other symptoms are characteristic of cataracts.


* Here is what can be done to reduce the risk of developing cataracts:

* Do not smoke

* Always wear a hat and sunglasses.

* Keep diabetes under control if you have it

* Limit alcohol intake.


In most cases, this is an age-related disease; more than half of people over 65 have such a diagnosis.But cataracts can also be congenital.It can also develop in children as a result of damage or eye disease.


The exact causes of the cataract are unknown.The risk of developing the disease increases with age.But the following factors may play an important role:

* Diabetes

* Smoking

* Alcohol abuse

* Mechanical damage to the eyes

* Long-term use of corticosteroids

* Prolonged exposure to solar radiation

* Also, ultraviolet radiation can sometimes cause cataracts and other visual impairments.


At the reception at the oculist or ophthalmologist.The specialist determines visual acuity, visual field, measures intraocular pressure, performs studies of the retina and optic nerve.Using a slit lamp, the doctor determines the degree of maturity of the cataract and lens opacities.

How to get rid of it?

If, as a result of a cataract, your vision has deteriorated so much that the situation cannot be corrected with glasses or contact lenses, you may need surgery.During the operation, the clouded lens is removed, replacing it with an artificial lens.

This operation is completely safe and very effective.If both eyes are affected by a cataract, the operation is performed first on one of them.

The most common and least traumatic way to remove cataracts today is phacoemulsification .The doctor makes a tiny incision and destroys the lens with ultrasound waves.The removed lens is replaced with an artificial intraocular lens.After such an operation, most often there is no need to wear glasses or contact lenses.

There is another way – installing intraocular lenses.This allows not only eliminating cataracts, but also eliminating the need to wear reading glasses, correcting hyperopia and myopia (multifocal intraocular lenses) and corneal astigmatism (toric intraocular lenses).


For several days after surgery, the eyes may be sensitive to light and itch.You may be prescribed special drops and recommended to wear an eye patch or goggles.The eyes are fully restored after the operation within eight weeks, although the vision improves much earlier.You may need to use reading glasses for a while.


Postoperative complications are extremely rare.The most common risks are associated with bleeding, infections, and changes in eye pressure.If detected early, the effects of these risks are treatable.In rare cases, surgery can cause retinal detachment, which requires immediate treatment.Sometimes the lens tissue left to maintain the lens may become cloudy, but this phenomenon is easily eliminated with a laser.


Only your ophthalmologist will decide this.In rare cases, a cataract needs to be removed immediately, but most often the vision changes occur gradually, and patients postpone the operation until the glasses and contact lenses stop helping.If the cataract does not cause you any obvious inconvenience, you can wait with the operation.
