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
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
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
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.
