What is Presbyopia?
Presbyopia is the loss of the lens' ability to change the focus of the eye through alignment. Presbyopia begins in the early forties and eventually everyone is affected.
The real problem is the same as in hyperopia. The focus of light rays from nearby objects remains behind the retina and is out of focus. In hyperopia, this is because the eyeball is shorter than normal. This is the case in presbyopia because the older lens becomes stiffer and less flexible. This makes it difficult or impossible to bend the light rays more sharply, which is necessary for harmony to occur, which brings the focal point in front of the retina.
Reading at night or in low light can be even more difficult when you're tired. Presbyopia occurs regardless of your visual defect.
The first symptom of presbyopia is the need to put objects away while reading. In the future, this blurred vision increases and pain occurs in the forehead and temple area. Focusing the eye on close objects by force brings other problems with it over time. After reading, it may also be temporarily difficult to see distant objects clearly, because distant objects also require alignment in order to be able to focus.
The only solution to presbyopia is mostly optical correction (reading glasses). People with corrective lenses for myopia need bifocals (the upper part is for distance vision and the lower part is for near vision) or they use two separate glasses.
Because of the progressive worsening of presbyopia, prescriptions written through the late 60s often change. When it comes to this age, presbyopia becomes stable. From the age of 60-65, the eye's focusing ability actually stops due to the loss of flexibility of the lens; At this stage, near vision becomes completely dependent on glasses. However, those who are nearsighted remove their distance glasses while looking close and can see more easily while doing their close work.
What Are the Symptoms of Presbyopia?
Presbyopia patients have difficulty in seeing and observing objests which are closer than 50 cm. Therefore, they can see objects away from them. In the future, if the near vision is still impaired, headache in the forehead and temple area may accompany.
How Is Presbyopia Treated?
There are many treatment methods applied on this subject in the world. These treatment methods have their own advantages and disadvantages. Currently, intraocular multifocal lens operations and presbyond laser treatments, which are accepted as the most reliable method for the treatment of presbyopia, are successfully applied in Turkey.
Treatment with Glasses
Bifocal Glasses
Multifocal (Progressive) Glasses
Contact Lens Treatment
Multifocal contact lenses: Patients who are suitable for lenses get successful results when they use these lenses. However, patients over the age of 40 may experience problems in use due to the decrease in tear quality.
Monovision with contact lenses (nearsightedness in one eye): Your suitability for this treatment can only be determined at your first examination.
An Option for Presbyopia Patients; PRESBYOND
In the aging eye, the problem of adaptation in close-up vision begins around the age of 45. By using the PRESBYOND Laser Compliance Field method, this compatibility problem can be overcome with a refractive surgery approach and good vision can be achieved at far, medium and close distances. It provides the opportunity to provide visual acuity by providing depth of visual field by making use of corneal refractive surgery, which allows extremely sensitive intervention.
By using spherical aberration, which is naturally found in the eye, the scope of personalized laser intervention expands to include more people than the conventional monovision laser method in many respects.
Suitable for Many Patients
A major advantage of treatment with the PRESBYOND Laser Compliance Field is that it is more patiently accepted than conventional monovision. The PRESBYOND Laser Adaptation Field is effective in treating presbyopia-related disorders in up to 97%, while in conventional monovision this figure remains at 59-67%. Even patients with astigmatism who do not need glasses at a distance can be treated. Indeed, it has far greater potential for success than any comparable method.
