Symptoms of astigmatism

El astigmatism It is a refractive error that occurs when the shape of the eye does not allow the cornea or lens to function properly and, therefore, it is not possible to focus properly.

To identify it, the main astigmatism symptoms It is blurred vision, headache and difficulty focusing small details from near and far.

What is astigmatism?

Astigmatism occurs when the light that comes from the objects is focused on more than one point of the retina preventing the images from being seen clearly.

The cause of astigmatism is a irregular curvature in several areas of the cornea, the transparent and external part of the eye.

Many people who suffer from this condition are not aware of it and spend years suffering from trouble to focus without knowing the reason.

Symptoms of astigmatism in children

El astigmatism in children usually presented as a genetic cause condition, that is, hereditary. Therefore, adults must be very attentive to any signal that may indicate that your child is beginning to suffer from this condition, so common, and that must be treated on time.

When this condition occurs in children it is usually accompanied by farsightedness or myopia, which is why among the main symptom of the child astigmatism find headache, dizziness, itchy eyes y eye congestion.

Astigmatism and other refractive errors in children usually deal with the use of glasses, Since the surgery to correct this vision problem must be performed from 18 years of age.

Symptoms of astigmatism in adults

Astigmatism is a condition that usually appears during childhood, however, as the years go by it can become more intense and further affect vision, which is why they can occur different symptoms in adults than in children.

The symptoms of astigmatism in adults are:

  • Eye irritation After forcing the view.
  • Redness of the eyes.
  • Tired sight.
  • Double vision or blurred.
  • Headache.
  • Ocular fatigue when focusing on a nearby object.
  • Inflammation of the eyes.
  • Difficulty driving at night.
  • Need to squint to be able to focus

It is possible for a person present mild astigmatism and don't know it. For this reason, in the presence of any of the symptoms mentioned above it is vital go to the eye doctor so you can perform an exhaustive examination to check if there is any deformity in the curvature of the cornea.

Types of astigmatism

Depending on type of astigmatism, this condition can affect vision to a greater or lesser extent.

The types of astigmatism are:

  • myopic astigmatism: it happens when one or both axes of the eye focus in front of the retina.
  • hyperopic astigmatism: it happens when one or both axes of the eye focus behind the retina.
  • Mixed astigmatism: it happens when one axis is focused in front of the retina and another behind. Usually, one meridian focuses as myopic and the other as hypermetropic.

Treatment without surgery

Once the symptoms of astigmatism are experienced, it is important to go to an ophthalmologist or eye doctor for an opportune diagnosis. Once the refractive error is confirmed, the vision problems can be treated by:

Glasses

The use of glasses is the simplest way to treat astigmatism symptoms quickly and effectively.

Depending on the results of the eye exam, the specialist ophthalmologist will prescribe the appropriate graduation to correct vision and recover visual sharpness.

If this option were to be chosen, it is essential to wear prescription glasses for night driving.

Contact lenses

All the contact lenses they act by becoming the first layer of refraction that will receive the rays of light that enter the eyes.

For this reason, for many people it is the best option to have a better approach and a clearer vision, since they offer a campor visual much more ampmess that glasses.

However, the use of contact lenses is much more expensive y requires a series of care that not all people are willing to assume.

Treatment with surgery

    All degrees of astigmatism can be corrected through a astigmatism refractive surgery.

    Astigmatism surgery is the only option to change way permanent bases the shape of the cornea and to correct so refractive error helping the rays of light to focus precisely on the retina and produce a clear vision.

    There are different techniques that we explain below:

    All the surgical techniques to treat astigmatisno They last 10 minutes, they are of type ambulatory and require the application of anesthesia through drops.

    FemtoLasik

    El FemtoLasik, is the technique of eye laser refractive surgery to correct the most modern astigmatism that exists today.

    Through the laser of Femtosecond we made a cut in the cornea and then, through the excimer laser we will correct the astigmatism that the patient has.

    This technique is the only type of fully laser refractive surgery to correct astigmatism.

    LASIK

    The technique Lasik It is the most used today. Consists in lift a thin layer of the cornea, with the help of a microkeratome (blade), to correct astigmatism with excimer laser, an instrument that will shape the shape of the cornea in approximately 45 seconds.

    PRK

    under the technique PRK se separates the most superficial part of the cornea (epithelium) with the use of an alcoholic substance and subsequently the Excimer laser is applied to correct the shape of the cornea.

    Subsequently, the epithelium and a protective lens are put back in place which must remain in the eye to protect it for a few days.
