PRESBYOPIA: AGE-RELATED NEARSIGHTEDNESS

Age-related nearsightedness is one of the most common cosmetic problems of humankind. While the patient is deciding on whether or not to have the surgery, cosmetic nature of the problem should be explained to the patient and no harm should be caused during the surgery.

PRESBYOPIA; The intra-ocular lens changes its shape to increase refractivity and focuses on the near. We can liken this to the zoom function of a camera.
After the age of 40, lenses lose this capability and experience difficulty focusing on near. This is result of physiological aging and eye-glass number increases by +1 number every ten years following age 40.

Difficulty seeing in the soft light, or holding the newspaper further to see it better are signs of presbyopia.

How do other eye diseases affect presbyopia?

While myopic patients can usually stop using their existing glasses after the age of 40 and see near, hypermetropic patients usually need a new set of reading glasses.
Presbyopia usually starts at forties and unfortunately can be seen in everyone. It is the most important problem still not solved by doctors of refractive surgery.

TREATMENT OF PRESBYOPIA

Eye-glass usage: Lenses called progressive that show near and far clearly are the most preferred treatment in the world. Although it takes a long time to get used to by the patient, they can be very comfortable later.

Multifocal Contact Lenses; If patients can adapt, they can be very satisfied with the results; however, dryness in eyes should be noted.

LCK-LightTouchConductive Keratoplasty; FDA approved this method was replaced with multifocal IOLs (intraocular lenses) 1-2 years ago.

This method has various advantages and disadvantages.

One of these advantages is that it is non-surgical; however, because it is a manual surgery, there are factors affecting surgery outcome depending on the person, such as sensitivity to light or moving the eye. On the other hand, lasik surgery is performed at a sensitivity level of microns.

While it is still used, it is no longer a widely-preferred method.

MULTIFOCAL INTRAOCULAR LENSES

It is a surgical method used on patients with cataract, and hypermetropy at over the age of 40, or myopic patients who would also like to see near.

Patient population this method is used on is over the age of 40, who have difficulty seeing near and far, and preferably have hypermetropy.

The most common complaint is glistening and diffusion of lights at night.

MONOVISION LASER TREATMENT

A full treatment is done on the person´s far-dominant eye. The other eye is treated more than a full treatment and is left at -0.75 -1.00 diopter myopic.

After all, presbyopia treatment is a cosmetic treatment. For this reason, we should not harm the patient. Patient selection is crucial.

In the future, this problem will be possible to be solved with efficient lenses.

NEW METHODS OF PERSBYOPIA TREATMENT

1) INTRACOR

This method that corrects near-vision and ends eye-glass usage is only done with Femtec Femtesecond Laser instrument developed specifically for IntracorPresbyopia treatment.
Femtosecond Laser focuses 15,000 laser beams per second at a micron-level accuracy on desired spots with high degree of sensitivity, creates 1-3 micron-sized bubbles containing water, and these bubbles cause histolysis.

As a result, Presbyopia can be done without cutting the outer layer of the eye or thinning the cornea fiber.

It is performed differently than Lasik treatment. While Lasik involves flap lacerations from the cornea, there is no need to perform flap lacerations from the cornea in this new treatment. Because there is no contact with the front surface of the cornea, it can be performed in a short period of 20 seconds, with no risk of pain and infection. It can be performed on thin and dry eyes.

The patient can go back to their normal lives right after the treatment. The advantage of this method over others is that it can be performed on both eyes and can correct near-vision without hindering far-vision.


Advantages

This treatment, also called Intra COR, is first performed on one eye, and can be performed on the other eye after 3 or 6 months. Contrary to other procedures, it does not affect far-vision. There is no harm on performing it on eyes that have previously had cataract or laser surgeries. READING GLASSES NUMBER OF approximately 2 D CAN BE CORRECTED...

Is it possible to obtain a success rate of 100 % after the surgery?

Its most important characteristic is that it corrects near-vision without hindering far-vision.

There is no risk of losing the eye with this method.

90 persons out of every 100 who have had this treatment became capable of reading the newspaper without reading glasses and their problems did not repeat.
This treatment cannot be applied to people with preliminary cataract or with thin cornea.

It is applied on patients not exceeding the age of 45.

Previous laser surgeries do not constitute an obstacle for this surgery.

2) SUPRACOR

Suppracor is a simple procedure to correct near-vision. During this procedure, excimelaser is applied to the external surface of the eye and reshapes the cornea delicately. Supracor is a safer procedure compared to other refractive procedures in presbyopia surgery.

The purpose of supracor treatment is to strengthen your near-vision to enable you to read writing you will see every day on the newspaper, restaurant menus, computers and cell phones without glasses. Supracor is a safe and effective method that corrects near and far vision in a single procedure without hindering far-vision.

IT IS A PRESBYOPIA SURGERY THAT LEAVES POSITIVIE RESULTS AND HAS A SUCCESS RATE OF 90 %.

SUPRACOR, is a new corneal method that can be applied with TeknolasExcimeLaser 217 P. It can be applied to both eyes at the same time due to its presbyopic algorithm. It can be applied in post-LASIK cases, as well as, Hypermetropic, Emmetropic and Myopic eyes. Both far and near vision can be corrected in a single procedure. Intracor was developed through experience and has become the best in the world. While other presbi-Lasik methods hinder far-vision by creating unwanted aberrations in the Pupil, this method does not create unwanted aberrations.

There are some suitability criteria for Supracor.

The treatment can be performed after these criteria are evaluated through examinations and measurements. Supracor can be applied on every eye that is suitable for Lasik. Eye diseases such as dry eyes, cataract, thin cornea, glaucoma, and keratoconus deem a patient unsuitable, as in lasik candidates.

While the success rate of Intracor was at 80%s, we managed to increase the success rate of near-vision treatments to 90% with Supracor. Also, for the first time far hypermetropy and near hypermetropy (presbyopia) were able to be treated simultaneously with Supracor. Its most important success, besides its success rate of 90%, is not to cause any losses in quality of far-vision. All other presbyopia treatments could result in losses in quality of far vision.
