Eye Disorders and Eye Surgery

In order for the eye to see clearly, it is necessary to refract the rays to the eye and focus on the mesh layer at the back of the eye called the retina. This refraction of light is provided by the cornea (the clearest layer outside the eye) and eye lens If the eye can focus the rays from different distances on the retina, the refractive function of the eye becomes normal and this is called emetropia. In eyes with refractive defects, the rays cannot focus on the retina and a blurred or distorted image is formed.

This occurs for two reasons:

What is Myopia?

It is a refractive defect in which the nearby objects are clear and the distant ones are blurred. Due to the excess length of the anterior and posterior eye or the refractiveness of the cornea and lens, the incoming rays focus in front of the retina, not on the retina.

What are the Symptoms and Symptoms of Myopia?

Especially in children, there may be complaints such as watching the television closely, not being able to see the board at school and squinting. Adults, on the other hand, experience a lack of clarity when driving and looking at the road or traffic signs. Other symptoms of myopic disease are headache, fatigue and pain in the eye.

Myopia usually begins at the age of 8-12 under the age of 20. It may show rapid progress in adolescence. It usually reaches a constant value around the age of 20. Myopic degrees;

Mild myopia if below 3 degrees,

Moderate myopia if in the range of 3-6 degrees

If it is 6 degrees and above, it is considered as high myopia.

Myopia may be mild or high. For the treatment of this defect, glasses, contact lenses and refractive surgery methods are used.

Since the glasses used for myopia have thick edges and the middle of the glass is thick, an aesthetic problem also arises. Even it is more advantageous than glasses, contact lenses can cause allergies and infections. In addition, the fact that it requires continuous maintenance is another disadvantage. Laser is a surgical method based on reshaping the cornea on the other hand. In cases where the laser is not possible, intraocular lenses appear as an option.

What is Hyperopia?

It is a refractive defect in which the incoming rays focus on the back of the retina, not on the top of the retina, because the anterior posterior length of the eye or the refractiveness of the cornea or lens is less than normal.

Infants and young children are usually hypermetropic. As the eye grows with age, hypermetropia usually decreases.

What are the Symptoms and Indıcations of Hyperopia?

The eye must adapt in order to reduce the image on the retina. Thanks to this harmony, young hypermetropes can see clearly both far and near. However, they may have complaints such as headache and fatigue in the eyes as they force the eye muscles to adapt. After close work, blurred vision, discomfort and fatigue occur in the person. The person sees nearby objects blurred and the letters snap together while reading something. The eye starts to get tired while it constantly tries to focus the light.. Symptoms of hyperopia due to eye fatigue are observed as blurred vision of objects or words, narrowing the eyes to see better, pain or burning sensation around the eyes, headache after looking at something nearby or reading. Cross-eye, known as strabismus in medical language, may occur if hypermetropia is not treated in children and infants. Hyperopia is also the cause of lazy eye. The degree of hyperopia is determined by the rate of refractive disorder. If this disorder

What is Astigmatism?

It is a type of refractive defect caused by the axes of the eyeball having different refractive power. Astigmatism is usually caused by the curvature of the cornea having a slightly egg shape Myopia can be seen as hyperopia or a mixture of the two, i.e. mixed astigmatism. Astigmatism can be at a regular 90 degree angle, or irregular astigmatism can occur due to corneal keratitis (infection), corneal ulcer, trauma and irregularities in the lens. The cause of astigmatism is also often inherited.

What are the Symptoms and Findings of Astigmatism?

There may be complaints such as blurred, double vision and shaded vision, headache and eye pain. Patients receiving heavy astigmatism see objects around them as distorted. If not corrected, it may lead to eye laziness. Glasses, contact lenses and refractive surgery are used in the treatment of astigmatism. Rarely, corneal implantation may be required.

What is Presbyopia?

It is the difficulty of seeing the relative that occurs with age. In young people, the eyepiece is elastic and easily adapts to ensure that nearby objects are clearly visible. With age, this elasticity decreases and close-up vision becomes difficult. Therefore, similar to the hyperopia, rays from nearby objects focus behind the retina. It starts at the age of 35-40 and progresses to the age of 60.

How is Presbyopia Treated?

Glasses or contact lenses can be applied in appropriate patients. There is also the possibility of refractive surgery for presbyopia. Especially when there is a high gap between the two eyes in hyperopia and astigmatism, the eye that is higher may have a persistently low level of vision because one of the eyes tolerates the diseased eye for a long time and the visual impairment is noticed late. It's called amblyopia, or lazy eye. Children should have a refraction examination at the latest 2 years of age. Because, especially after the age of 7-8, it is more difficult to treat in terms of early diagnosis. Despite different treatment methods such as neurovision, the most effective treatment is still early treatment and eye closure treatment.
