keratoconus Treatment in Iran

keratoconus Treatment in Iran

Keratoconus Treatment

A condition in which the clear tissue on the front of the eye (cornea) bulges outward. With keratoconus, the clear, dome-shaped tissue that covers the eye (cornea) thins and bulges outward into a cone shape. Its cause is unknown. Symptoms first appear during puberty or the late teens and include blurred vision and sensitivity to light and glare. Vision can be corrected with glasses or contact lenses early on. Advanced cases may require a cornea transplant.

In the early stages of keratoconus, you might be able to correct vision problems with glasses or soft contact lenses. Later, you may have to be fitted with rigid, gas permeable contact lenses or other types of lenses, such as scleral lenses. If your condition progresses to an advanced stage, you may need a cornea transplant.

A new treatment called corneal collagen cross-linking may help to slow or stop keratoconus from progressing, possibly preventing the need for a future cornea transplant. This treatment may be offered in addition to the vision correction options above.

Symptoms of Keratoconus

Signs and symptoms of keratoconus may change as the disease progresses. They include:

. Blurred or distorted vision

. Increased sensitivity to bright light and glare, which can cause problems with night driving

. A need for frequent changes in eyeglass prescriptions

. Sudden worsening or clouding of vision

Causes of Keratoconus

No one knows what causes keratoconus, although genetic and environmental factors are thought to be involved. Around 1 in 10 people with keratoconus also have a parent with the condition.

Risk factors

These factors can increase your chances of developing keratoconus:

. Having a family history of keratoconus

. Rubbing your eyes vigorously

. Having certain conditions, such as retinitis pigmentosa, Down syndrome, Ehlers-Danlos syndrome, hay fever and asthma

Complications

In some situations, your cornea may swell quickly and cause sudden reduced vision and scarring of the cornea. This is caused by a condition in which the inside lining of your cornea breaks down, allowing fluid to enter the cornea (hydrops). The swelling usually subsides by itself, but a scar may form that affects your vision.

Advanced keratoconus also may cause your cornea to become scarred, particularly where the cone is most prominent. A scarred cornea causes worsening vision problems and may require cornea transplant surgery.

When to see a doctor

See your eye doctor (ophthalmologist or optometrist) if your eyesight is worsening rapidly, which might be caused by an irregular curvature of the eye (astigmatism). He or she may also look for signs of keratoconus during routine eye exams.

Diagnosis

To diagnose keratoconus, your eye doctor (ophthalmologist or optometrist) will review your medical and family history and conduct an eye exam. He or she may conduct other tests to determine more details regarding the shape of your cornea. Tests to diagnose keratoconus include:

. Eye refraction. In this test your eye doctor uses special equipment that measures your eyes to check for vision problems. He or she may ask you to look through a device that contains wheels of different lenses (phoropter) to help judge which combination gives you the sharpest vision. Some doctors may use a hand-held instrument (retinoscope) to evaluate your eyes.

. Slit-lamp examination. In this test your doctor directs a vertical beam of light on the surface of your eye and uses a low-powered microscope to view your eye. He or she evaluates the shape of your cornea and looks for other potential problems in your eye.

. Keratometry. In this test your eye doctor focuses a circle of light on your cornea and measures the reflection to determine the basic shape of your cornea.

. Computerized corneal mapping. Special photographic tests, such as corneal tomography and corneal topography, record images to create a detailed shape map of your cornea. Corneal tomography can also measure the thickness of your cornea. Corneal tomography can often detect early signs of keratoconus before the disease is visible by slit-lamp examination.

Keratoconus Treatment

Treatment for keratoconus depends on the severity of your condition and how quickly the condition is progressing. Generally, there are two approaches to treating keratoconus: slowing the progression of the disease and improving your vision.

If your keratoconus is progressing, corneal collagen cross-linking might be indicated to slow or stop the progression. This is a newer treatment that has the potential to prevent you from needing a cornea transplant in the future. However, this treatment does not reverse keratoconus or improve vision.

Improving your vision depends on the severity of keratoconus. Mild to moderate keratoconus can be treated with eyeglasses or contact lenses. This will likely be a long-term treatment, especially if your cornea becomes stable with time or from cross-linking.

In some people with keratoconus, the cornea becomes scarred with advanced disease or wearing contact lenses becomes difficult. In these people, cornea transplant surgery might be necessary.

Lenses

. Eyeglasses or soft contact lenses. Glasses or soft contact lenses can correct blurry or distorted vision in early keratoconus. But people frequently need to change their prescription for eyeglasses or contacts as the shape of their corneas change.

. Hard contact lenses. Hard (rigid, gas permeable) contact lenses are often the next step in treating more-advanced keratoconus. Hard lenses may feel uncomfortable at first, but many people adjust to wearing them and they can provide excellent vision. This type of lens can be made to fit your corneas.

. Piggyback lenses. If rigid lenses are uncomfortable, your doctor may recommend "piggybacking" a hard contact lens on top of a soft one.

. Hybrid lenses. These contact lenses have a rigid center with a softer ring around the outside for increased comfort. People who can't tolerate hard contact lenses may prefer hybrid lenses.

. Scleral lenses. These lenses are useful for very irregular shape changes in your cornea in advanced keratoconus. Instead of resting on the cornea like traditional contact lenses do, scleral lenses sit on the white part of the eye (sclera) and vault over the cornea without touching it.

If you're using rigid or scleral contact lenses, make sure to have them fitted by an eye doctor with experience in treating keratoconus. You'll also need to have regular checkups to determine whether the fitting remains satisfactory. An ill-fitting lens can damage your cornea.

Therapies

. Corneal collagen cross-linking. In this procedure, the cornea is saturated with riboflavin eyedrops and treated with ultraviolet light. This causes cross-linking of the cornea, which stiffens the cornea to prevent further shape changes. Corneal collagen cross-linking may help to reduce the risk of progressive vision loss by stabilizing the cornea early in the disease.

Surgery

You may need surgery if you have corneal scarring, extreme thinning of your cornea, poor vision with the strongest prescription lenses or an inability to wear any type of contact lenses. Depending on the location of the bulging cone and the severity of your condition, surgical options include:

. Penetrating keratoplasty. If you have corneal scarring or extreme thinning, you'll likely need a cornea transplant (keratoplasty). Penetrating keratoplasty is a full-cornea transplant. In this procedure, doctors remove a full-thickness portion of your central cornea and replace it with donor tissue.

. Deep anterior lamellar keratoplasty (DALK). The DALK procedure preserves the inside lining of the cornea (endothelium). This helps avoid the rejection of this critical inside lining that can occur with a full-thickness transplant.

Cornea transplant for keratoconus generally is very successful, but possible complications include graft rejection, poor vision, infection and astigmatism. Astigmatism is often managed by wearing hard contact lenses again, which is usually more comfortable after a cornea transplant.

10 common question about keratoconus

1Can keratoconus be corrected?
Keratoconus treatment In the mildest form of keratoconus, eyeglasses or soft contact lenses may help. may help. But as the disease progresses and the cornea thins and becomes increasingly more irregular in shape, glasses and regular soft contact lens designs no longer provide adequate vision correction.
2Can keratoconus be cured?
Currently there is no cure for keratoconus. It is a lifelong eye disease. Thankfully, however, most cases of keratoconus can be successfully managed. For mild to moderate keratoconus, scleral contact lenses made of advanced rigid gas permeable lens materials typically are the treatment of choice.
3Can keratoconus be treated by laser surgery?
However, the changes to the cornea make it impossible for the eye to focus without eyeglasses or contact lenses. Keratoconus can be dangerous if laser vision correction surgery (LASIK or PRK) is performed on the eye, because it can make the condition worse.
4Can you go blind if you have keratoconus?
A: Keratoconus does not typically lead to complete blindness. But the disease can degrade vision to a level where one will experience difficulty leading a normal life. ... A: If someone has very mild keratoconus, then it is possible that they may not require glasses or contact lenses after receiving keratoconus treatment.
5How quickly does keratoconus progression?
KERATOCONUS MAY PROGRESS FOR 10 TO 20 YEARS OR LONGER Keratoconus usually starts after puberty or in the early teenage years. Both eyes are usually affected but not to the same extent. The active period of keratoconus lasts for around 5 years.
6Is Keratoconus serious?
Keratoconus is an eye disease that may or may not cause loss of visual acuity that is severe enough to be considered a disability. ... Thankfully, in most cases, treatments such as scleral contact lenses and/or corneal cross-linking can prevent even advanced keratoconus from causing this level of severe vision loss.
7Can I live a normal life with keratoconus?
The good news is that it does not have to be this way and that patients with keratoconus can go on to live normal lives just like any other person with good sight.
8What causes keratoconus to get worse?
When the fibers are weakened, they cannot hold their shape. This causes the cornea to change from a dome to more cone-like in shape. When the Collagen continues to weaken, the Keratoconus gets worse, and there are factors that contribute to this.
9What happens if Keratoconus is not treated?
This condition can also cause swelling and scarring of your cornea. These changes to the cornea can cause vision problems, such as nearsightedness (myopia) and astigmatism. Keratoconus has different types. They are based on the shape and location of the thinned cornea.
10Can keratoconus go away on its own?
In most people who have keratoconus, both eyes are eventually affected, although not always to the same extent. ... With severe keratoconus, the stretched collagen fibers can lead to severe scarring. If the back of the cornea tears, it can swell and take many months for the swelling to go away.

    What is mild keratoconus? Is it about eyelid?

    • Iranian Surgery Adviser says:

      The keratoconus consists of five stages of development, depending on which stage of treatment the individual is in.
      These include: Pre-Corneal Stage, Mild Stage of Disease, Moderate Disease Stage, Severe Progressive Stage, and the last stage where the disease progresses to the point where corneal transplant surgery is required.

      When the keratoconus is mild, one’s vision can be corrected with glasses. If the disease progresses to a greater extent, one should use hard contact lenses in order to be able to see better.

    hey there. I’m a 48 year old female with keratoconus problem. I’m a none smoker athlete and haven’t done any eye surgery and I don’t use any contact lenses but somehow I have keratoconus
    is there a way to cure my sickness with any method that doesn’t Involve surgery?

    • Iranian Surgery Adviser says:

      Keratoconus does not fade on its own. The shape of your cornea can’t permanently change, even with medications, special contact lenses, or surgery. Remember, we have various options for reshaping your cornea, but keratoconus is a chronic, lifelong disorder.
