Presbyopia Treatment

Presbyopia, which is a problem of not being able to see closely, is an age-related vision defect. Presbyopia, especially seen in people aged 40 and over, is a discomfort that the lens loses its flexibility with advancing age and is unable to see the relatives. 

The lens, which has the ability to change shape, has a flexible structure. The lens that swells in order to provide high-quality vision in close distance provides the opportunity to see better. The lens, which is deformed especially with the advancing age after the age of 40, loses this feature and does not provide quality vision at close range. The main feature that distinguishes presbyopia from hyperopia is the age factor. 

The defect of the focal point of the incoming rays in the hyperopia, that is, behind the retina, causes imperfection. Hyperopia, which is not dependent on age and can be seen in young people, is due to the shorter than normal eyeball. Presbyopia occurs due to the aging of the eye lens by losing its elasticity due to aging.

FAQ about Presbyopia

The most commonly used method in the treatment of presbyopia is glasses. While aiming a clearer vision with glasses treatment, eye and headaches due to presbyopia are also eliminated. Another treatment method used besides glasses is using lenses. 

You can use the lenses that you have provided with a doctor’s prescription in accordance with the degree of your eyes. In addition to the distant problem, people who have difficulty in seeing the relatives prefer multi-focus progressive lenses. 

If you don’t want to wear two glasses and want to have clear vision with monocle glasses, it may be better for you. You can also choose progressive glasses as well as bifocal lenses with double focus. The main feature that distinguishes progressive glasses from bifocal glasses; progressive lenses have 3 focal points, far middle and close, while bifocal lenses have 2 focal points far and close. There is also a sharp line in the middle of the bifocal lenses that separates the far and near focus point.

When an object at a distance is close, the signals reaching the brain are evaluated and transmitted back to the eye. In line with the signals transmitted to the brain, with the contraction and relaxation of the eye muscles, it is stretched and relaxed with fibers. However, depending on the age, the eye muscles lose this feature and vision defects occur at close range over time. 

Vision defect, which increases every year after the age of 40, increases its effect over time. However, people with nearsightedness see better, and the two diseases overlap and show a defect-reducing effect. In other words, people who have difficulty in seeing far will see their relatives better. 

The problem of not seeing relatives, which started in the 40s, varies continuously until the age of 60. The degree that increases with time becomes stagnant after the age of 60. The lens, which loses its flexibility and hardens, actually loses its ability to focus after 60 and 65 years of age. For presbyopia patients, reading glasses after the age of 60 are indispensable. However, people with myopia will see much more clearly that they have removed their distance glasses.

The most common symptom in presbyopia patients is that they realize while reading a newspaper or book. Presbyopia patients, who provide better vision farther away, need to constantly remove the objects they read or the articles they read. Over time, they encounter problems such as blurred vision, pain in the forehead and temple parts. They have difficulty focusing and concentrating when dealing with tasks that require attention at close range. After a presbyopia patient reading a book or newspaper for a while, he has difficulty seeing the distance clearly.

Myopia Treatment

An eye with a blurred distance and a clear eye is called a myopic eye. Myopia is not a disease or discomfort, but just a focusing defect that can be fixed with glasses or lenses. This visual defect is eliminated with concave, that is, lenses that scatter light.

Myopia_color the formation of the image in front of the retina layer, which senses light inside the eye, creates a blurred image. Just like a camera with a close focus, the image is blurry away and is very clear soon.

FAQ about Myopia

  • If the eye is too long, the image appears in front of the retina.
  • If the eye is too strong, it creates the image in front of the retina.
  • Low myopia: up to -3.50
  • Middle myopia: from -3.50 to -6.00
  • High myopia: higher than -6.00

Congenital myopia: It is known as child myopia. It continues from birth to childhood. Therefore, it is necessary to take the children to regular eye exams from the first 6 months.

Youth myopia: It occurs in the 20s.

School age myopia: Occurs during childhood, especially during school age. In this form of myopia, the eye gets tired from looking nearby while working.

In early adulthood: It starts between the ages of 20 and 40.

In late adulthood: Seen after age 40.

Since myopes who cannot see far can see their relatives clearly, they become very advantageous since they can easily see the relatives during presbyopia, after 40 years of age.

Daytime vision of myopic individuals is slightly better than night vision. The reason is that because the pupil is closed with daytime light, the rate of fuzzy light entering the eye decreases, so myopic people get clear vision when they squeeze their eyes. Likewise, a myopic person without glasses can clearly see the articles he / she cannot read and the objects that he cannot see by opening a hole in the paper with a needle.

Cataract Treatment

We can compare our eyes to a camera or a camera. When the light is reflected from the objects around us and enters our eyes and focuses on the point of view by breaking it, clear vision emerges.

With the formation of cataracts, rays reflected from the objects do not fully focus at the point of vision and clear vision is not possible. Since the lens, which has lost its transparency completely, will prevent the passage of light, it is not possible for the person to see his / her environment and this is a blindness, and its treatment is surgery.

FAQ about Cataract

Cataract formation is generally proportional to age. Cataract formation begins as a result of the aging of the lens in middle-aged and older people. The eyepiece (lens) that accumulates protein and old cells cannot be expelled because it is closed and causes eye to lose its transparency. At the same time, not using sunglasses causes cataracts to occur at an earlier age. The use of cheap and unhealthy sunglasses triggers cataract formation with more eye damage. Other causes besides aging, which is the main cause of cataracts;

  • Diabetes
  • Hypertension
  • Thyroid gland diseases
  • Prolonged exposure to sunlight, i.e. not using sunglasses
  • The blow to the eye
  • Long-term drug use
  • Vitamin C deficiency
  • Diseases such as measles and measles used by the mother during pregnancy cause cataracts in the baby.

The first symptom of cataracts is decrease in vision. The most important symptoms are getting disturbed by light at nights, having decreased vision in the dark or in the sunlight, faded colors and yellowing in colors.

Cataract, a disease that is very important and can cause blindness even though it is not treated, cannot be treated with medication. Treatment of the patient is done only by surgery. The frequently used treatment method is “Phacoemulsification”. Nowadays, a small hole is placed in the eye with a method with a high success rate. There is no need for narcosis in a very short process.

Cataract surgeries are performed in the hospital as an outpatient treatment. The pupils are enlarged by applying drops in your eyes 1 hour before cataract surgery. The eyes are usually numbed with drops. With the phaco method, which is the type of cataract surgery, entry is made into the eye through a 2 mm incision. With the ultrasound energy, the cataract layer is melted and taken out, the intraocular lens is placed. The duration of cataract surgery is 15 minutes. The vision levels of patients who are operated with the phaco method increase in a short time. They can return to their daily lives shortly after surgery. You can do your daily activities like reading, watching TV and driving in a few days.

Lasik Surgery

LASIK

LASIK is a surgical procedure applied to reduce the person’s dependence on glasses or contact lenses and takes its name from the initials of the Laser-Asisted In SituKeratomileusis (laser shaping of the cornea). In the LASIK method, the transparent corneal layer covering the front part of the eye, such as watch glass, is permanently reshaped with excimer laser to eliminate the existing refractive error. LASIK surgery has been successfully applied to more than 8 million eyes since the mid-1990s.

Excimer laser device has the ability to shape the cornea layer with an accuracy of 0.25 microns by using ultraviolet laser beam at 193nm wavelength. As a result of scientific researches, LASIK method has been found to be safe in myopia treatment – up to 10 diopters, in hypermetropia treatment up to + 6 diopters and in astigmatism treatment up to 6 diopters. However, depending on the eye structure of each person, the maximum degree of refraction that can be treated is different.

Lasik Surgery and After

In order to get the best results from LASIK surgery, you should stop using contact lenses as before the evaluation examination before surgery. It is important to discontinue use of all kinds of cosmetics such as make-up and perfume on the day before the surgery, as the residues on the bottom of the eyelashes increase the risk of infection. 

Since your vision will not be very clear due to irrigation, stinging and sensitivity to light immediately after the operation, you should come with a relative who will help you on the day of surgery and have dark sunglasses with you. You will not need to take off your clothes during the surgery. We recommend that you wear comfortable clothes when coming to the surgery and prefer shirt-style clothes instead of sweaters for ease of undressing after surgery.
