What is Visual Impairment?

In order for the eye to see clearly, the incoming rays must be refracted correctly, and as a result of this refraction, the image must focus on the retina at the back of the eye. Light is refracted through the cornea, the most transparent part of the eye, and the lens. When light from different distances is refracted correctly and the image focuses clearly on the retina, this is called emmetropia. When this delicate balance is disturbed, visual impairment occurs.

What are the Symptoms of Visual Impairment?

In eyes with visual impairment, rays coming from different angles cannot focus correctly on the retina. This leads to a blurred and asymmetrical image. This condition can manifest itself with various symptoms. Common symptoms due to refractive errors should be shown to a specialist. So, what are the symptoms of visual impairment?

  • Numbness and pain in the eye.
  • Burning and burning sensation.
  • Lachrymation and burrs in the eyes.
  • Itching and redness of the eyes.
  • Narrowing of visual fields.
  • Symptoms such as decreased vision are common.
These symptoms can also include droopy or swollen eyelids. These symptoms can increase the negative impact of visual impairment on daily life.

How to Treat Visual Impairment?

Visual impairments usually last a lifetime as they are caused by differences in the anatomical structure of the eye. However, with available treatment methods, it is possible to alleviate the symptoms of this condition and provide a more comfortable life.

Sometimes, these impairments may be asymptomatic for many years, but may suddenly appear with advancing age. While mild vision problems are usually corrected with glasses or contact lenses, more severe cases require surgery or laser techniques. Laser techniques and smart lens applications are generally preferred for patients seeking a permanent solution.

Smart lenses are special lenses implanted in the eye. Dulling or loss of flexibility of the natural lens in the eye can lead to various visual impairments. In this case, the eye loses the ability to see near or far. Smart lens application is a frequently used method in cataract treatment. Here, the deteriorated natural lens is replaced with a lifelong smart lens. In addition, smart lens treatment can also be applied for visual impairments such as high-grade hyperopia, myopia and astigmatism. Laser eye surgeries are performed with different techniques such as Femto LASIK, PRK, i-LASIK and LASIK. In this way, it becomes easier for patients to regain eye health.

Visual Impairment Treatment with Laser

Laser vision correction is an important treatment method that is widely preferred today. This method, popularly known as “eye scratching”, is a safe technology approved by the World Health Organization.

Laser visual impairment treatment is usually painless. This method, known as a mild operation, is applied with different techniques such as Femto LASIK, PRK, i-LASIK and LASIK. Therefore, the process after laser vision correction is quite comfortable.

Types of Visual Impairment

Refractive problems are the basis of eye diseases that occur for various reasons. Such problems are usually categorized under four main headings: hyperopia, myopia, astigmatism and presbyopia. So, what are the types of visual impairment?
Hyperopia (Near Vision Impairment)
Hyperopia is the inability to see close objects clearly. It is generally thought to be caused by genetic factors. This condition is caused by the anterior-posterior diameter of the eye being shorter than normal. People over 40 years of age may experience both near and distance vision problems as the degree of hyperopia increases. People with hyperopia have to read by shifting letters and lines. They may also see letters intertwined in close texts. Prolonged reading can cause headaches and discomfort around the eyes. Treatment options include the use of glasses or contact lenses. However, in advanced stages, intraocular lens surgery may also be preferred.
Myopia (Distance Vision Impairment)
Myopia refers to the inability to see distant objects clearly. This is usually caused by the rays focusing in front of the retina. It develops when the length of the front and back of the eye is too long or the refractive power of the retina is higher than normal. Myopia is characterized by mild to moderate degrees. It is usually treated with glasses or contact lenses, but surgical methods are also available as an option. Due to aesthetic concerns, many patients prefer contact lenses more than glasses.
Astigmatism
Astigmatism is a visual impairment usually caused by a deformity of the cornea or the lens of the eye. People with astigmatism see objects in a blurred and hazy way. This can cause the edges of objects to spread or elongate. Damage to the eye can also trigger astigmatism. Treatment methods include glasses, contact lenses and laser surgery.
Presbyopia
It is a nearsightedness disorder that occurs when the lens of the eye loses its ability to focus with aging. This condition develops when the lens in the eye loses its flexibility and hardens. Although it has similar symptoms to hypermetropia, the causes are different. While hyperopia is due to a shorter than normal eyeball, presbyopia is an aging-related process. The most common method of treatment is to use reading glasses. Individuals who are uncomfortable with glasses may prefer contact lenses. In both cases, the appropriate type of lens or glasses, which should be prescribed by a doctor, is determined by the patient’s comfort level.
These types of visual impairment, along with their treatment methods, should be carefully considered to maintain eye health and improve quality of life.

Sudden Vision Loss

Vision loss is an important health problem that seriously affects the quality of life of individuals. Especially sudden visual impairment can lead to feelings of shock and confusion. To prevent permanent vision loss, it is vital to consult a doctor immediately in case of sudden vision loss.

People who lose weight rapidly and those who work under intense stress are at higher risk for this condition. Around 80% of people with vision loss worldwide have a condition that is preventable or treatable. This shows how important it is to seek medical help immediately for any problems that arise in eye health. In cases such as sudden vision loss, the seriousness and urgency of the loss should not be underestimated.

Loss of vision can sometimes be short-lived and go unnoticed, or it can be so mild that it is not taken seriously. Therefore, it is important to pay attention to the symptoms to avoid wasting time and to consult a specialist immediately if necessary. Early intervention in case of vision loss can prevent permanent problems and help individuals maintain their quality of life. For healthy eyes, regular check-ups and awareness play a critical role in early detection of conditions that threaten eye health. It should not be forgotten that taking care of eye health offers a better experience in all areas of life.

Recovery After Visual Impairment

Itching, discomfort, burning and watering in your eyes are normal during the healing process after visual impairment. At first, your vision may be blurred. Usually pain is minimal and your vision will improve quickly. To keep you comfortable, your doctor may give you pain medication or eye drops to use for a few hours after the procedure.

You may also be advised to wear a protective device over your eyes at night during the healing process. You can see immediately after surgery. However, your vision will not be clear immediately. The healing and vision stabilization process usually takes 2 to 3 months. You will have a follow-up appointment with your ophthalmologist within 1 to 2 days after surgery. At this appointment, your doctor will observe the healing process of your eye and check for any complications.

It is important that you do not neglect the follow-up appointments recommended by your doctor during the first 6 months. During recovery from visual impairment, it may take several weeks before you can use cosmetics around the eyes again. You may also need to avoid strenuous physical activities and situations that can damage the area for a certain period of time. It is important to pay attention to your doctor's recommendations about when to return to your normal daily activities. Protecting your health by following your doctor's advice during this process will speed up your recovery process.

Visual Impairment Costs

Major advances in vision impairment treatment options in recent years have enabled patients to be treated more quickly and effectively. Therefore, there are several factors that determine the cost of visual impairment. The location and equipment of the health institution where the operation will be performed, the experience of the surgeon and his team, and the quality of the materials used are among these factors.

It is important that the patient undergoes a detailed examination before the visual impairment surgery and the most appropriate treatment method is determined. Without completing this process, it is not possible to give clear information about the cost of visual impairment.
