Presbyopia or presbyopia: lasers and eye training


Refractive surgery

Refractive surgery changes the shape of the cornea.

For presbyopia, this treatment can be used to improve near vision of the non-dominant eye (similar to monovision with contact lenses).

The American Academy of Ophthalmology recommends that people try contact lenses with monovision to determine if they are sufficient to correct presbyopia before considering refractive surgery.

Refractive surgery is not possible for everyone, it is necessary to perform some examinations to assess, for example, the thickness of the cornea, its curvature, etc.

Conductive keratoplasty (CK). In this procedure, the energy of radio waves is used to apply heat to very small areas of the cornea.
In this procedure, the cornea in the outer ring is shrunk, making the corneal curvature steeper.
The change in corneal curvature depends on the number and size of the areas to be treated.

The results of CK are different and do not have long-term effect for many people.

Laser-assisted in situ keratomileusis (LASIK). This procedure is carried out as follows:

  1. The surgeon uses a special laser or instrument called a keratome to lift a thin flap out of the corneal tissue.
  2. The surgeon then uses an excimer laser to remove the inner layers of the cornea and increase the degree of curvature compared to the much too round shape that currently exists.

An excimer laser differs from other lasers in that it does not generate heat.
A newer procedure, called Epi-LASIK, was designed to avoid some of the risks associated with LASIK.
Epi-LASIK provides for the separation of the epithelium from the corneal stroma by using a so-called epicular atom instead of an alcoholic solution.

Epithelial keratomileusis (LASEK). Instead of an incision in the cornea, the surgeon proceeds as follows:

  1. He puts a valve in the corneal epithelium.
  2. He then uses an excimer laser to model the outer layer of the cornea and increase the degree of curvature.
  3. At the end, the epithelial valve is reattached.

Photorefractive keratectomy (PRK). This procedure is similar to LASEK, but the surgeon removes and eliminates the epithelium.
This grows back and adapts to the new corneal shape.

Intraocular lens implantation for presbyopia

Another procedure used by eye specialists is the removal of the natural lens and its replacement for a synthetic lens inside the eye (intraocular lens implantation).
The latest intraocular lens implants are designed to allow the eye to see near and distant objects.
However, these special implants have not yet brought completely satisfactory results. The optical advantages of these lenses are sometimes overshadowed by side effects, such as glare sensitivity and blurred vision.

In addition, this procedure carries the same risks as conventional cataract surgery:

However, the development of the latest technologies is likely to improve these systems in the future.

Corneal inserts
A new procedure is the insertion of small plastic rings (Intacs) at the edge of the cornea.
However, this intervention does not bring the desired results and is still considered experimental.
Although the rings can also be removed, this operation is not without risks.

Natural treatment for presbyopia

The eyes are made of living tissue that can change and adapt.
According to nature hygiene, the use of glasses can worsen the situation because the eye gets used to not having to do anything to focus on the images.
Presbyopia is the result of a lack of coordination between the two eyes, for example, one looks at an object while the other looks in a slightly different direction (further to the right, left, up or down).

Nutrition and diet for presbyopia
Nutrition plays a fundamental role in the treatment of the eyes.
Good digestion promotes a peaceful sleep and causes the eyes to be less irritated and tired during the day.

There are two nutritional theories that have helped many patients:

  1. The blood group diet according to Dr. D’Adamo/Mozzi.
    According to this diet, the diseases are caused by some foods that can be harmful to members of a certain blood group.
    For the people of a different blood type, there are other pollutants and other permitted foods.
    Allowed foods:
  • Vegetables are basically allowed to everyone.
  • You can eat meat, but red meat should be avoided for blood types A and AB.
  • Fish may be consumed by everyone, but beware of crustaceans.
  • Fruit is allowed, especially in summer; only blood type 0 may have some symptoms.
  • Everyone is allowed to eat eggs.
  • Some nuts and seeds are recommended, but one should not exaggerate the amounts and

Beware of Erdnüssen.Es there are some foods that can basically cause diseases and symptoms:

  • sausages and pork;
  • milk and dairy products;
  • Gluten; Members of blood groups 0 and B must also limit or omit other cereals altogether, but can eat pseudocereals (quinoa, buckwheat and amaranth);
  • Chewing gum;
  • sugared and light drinks;
  • fried and smoked foods.
  1. The vegan diet/raw food diet is based on raw, simple and natural foods.
    This type of nutrition focuses on the duration of digestion. Quickly digested foods do not cause fermentation and rot in the intestines.
    In this way, diseases and diseased blood can be avoided.
    The human body has the same digestive system as frungivores (chimpanzees, gorillas, etc.), so we should eat the same foods with vegan and generally raw diets.
    The natural medicine of Lezaeta and hygienism advocate such a diet and are against drugs because they are considered poisons.
    Allowed foods include:
  • Fruit
  • raw vegetables,
  • Pulses
  • Nuts
  • Seed
  • Potatoes
  • The cooking of food should be avoided as much as possible, especially at high temperatures, steaming is preferable.

Exercises against presbyopia

You can look at the sun for a few seconds; this exercise can be done in the early morning or late afternoon.
For very light-sensitive eyes, the eyelids should remain closed; in this case you need to stay in the sun for a few minutes.

Examples of eye muscle exercises to improve vision:

All exercises must be repeated at least 20 times.

  1. Look as far up as possible and then with effort a little more; Then look down as far down as possible.
  2. Like the previous exercise, but in a horizontal direction: first look to the right and then to the left.
  3. Fix the most extreme point at the top left, then direct your gaze to the bottom right.
  4. Turn the pupil in a circle, first in one direction, then in the other.
  5. Look at the bridge of the nose and then rest the eyes.

Natural remedies for presbyopia

According to conventional medicine, one can help to maintain vision with the following precautions:

  • Perform regular eye exercises.
  • Keeping chronic diseases under control that could lead to vision loss, such as diabetes or high arterial blood pressure.
  • Wear sunglasses.
  • Wear goggles when performing activities that could cause eye disorders.
  • Put on glasses that allow good correction.
  • When reading, choose a sufficiently lit place.
  • Healthy nutrition. It is recommended to eat fruits, green leafy vegetables and other vegetables. These foods contain high levels of antioxidants such as vitamin A and beta-carotene, and are also important for keeping the eyes healthy.
  • Method according to Bates. Dr. Bates has found that people with impaired vision move their eyes less than others. This fact and the fatigue of the muscles lead to vision loss. The method according to Bates consists of a series of exercises based on movement, centralization and relaxation of the eyes.
