For presbyopia, this treatment can be used to improve close-up vision in the non-dominant eye (equivalent to wearing monovision contact lenses).

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

Not everyone can undergo refractive surgery; it is necessary to do some tests to evaluate, for example, the thickness of the cornea, the curvature, etc.

Conductive keratoplasty (CK) . This procedure sends radiofrequency energy to apply heat to very small areas of the cornea.
With this type of intervention, the cornea is narrow in the outer ring, the result is an extroversion (protrusion) of the central part.
The change in corneal curvature  depends on the number and size of the area being treated.

The results of CK vary and are not valid in the long term for many people.

Laser-assisted in situ keratomileusis (LASIK)
With this procedure:

  • The surgeon uses a laser or instrument called keratome to lift a thin flap of tissue from the cornea.
  • Then the surgeon uses an excimer laser to remove the inner layers of the cornea and increase the degree of curvature regarding the very rounded shape it currently has.

An excimer laser is different from other lasers because it does not produce heat.
A more recent procedure called Epi-LASIK was developed to avoid some of the risks associated with LASIK.
In Epi-LASIK the surgeon performs the separation of the epithelium from the corneal stroma, using an instrument called epikeratome instead of an alcoholic solution.

Laser-Assisted-Epithelial Keratomileusis (LASEK)
Instead of making an incision in the cornea, the surgeon:

  • Creates a flap only on the epithelium of the cornea.
  • It then uses an excimer laser to reshape the outer layers of the cornea and increase the degree of curvature,
  • Finally, reposition the epithelial flap.

Photorefractive keratectomy (PRK). 
This procedure is similar to LASEK, but the surgeon removes and eliminates the epithelium.
This naturally grows again, adapting to the new shape of the cornea.

Intraocular lens implants for  presbyopia

Another procedure used by some ophthalmologists is the removal of the natural lens and its replacement with a synthetic lens inside the eye (intraocular lens implant).
The latest intraocular lens implants are designed to allow the eye to see objects from near and far.

However, these special implants did not give completely satisfactory results. The optical advantages of these lenses are sometimes outweighed by visual side effects such as blurring and blurred vision.

In addition, this surgery has the same risks of a conventional cataract surgery :

  1. Inflammation ,
  2. Infection ,
  3. Hemorrhage ,
  4. Glaucoma,
  5. Retinal displacement .

However, the development of newer technologies will probably improve these implants in the future.

Corneal Ring or Intacs
A new surgical procedure involves the insertion of small plastic rings (Intacs) at the edge of the cornea.
However, this surgery did not give the expected results and is still considered experimental.
Although the rings can be removed, the operation is not risk free.


Natural Treatments for Presbyopia

The eyes are made up of living tissue that can change and adapt.
According to natural hygiene, wearing glasses can worsen the situation because the eye gets used to not working to focus the images.
Presbyopia is a consequence of lack of coordination between the two eyes, for example, one looks at one object, but the other looks in a different direction (more to the right, to the left, up or down).

Correct diet and exercise can greatly improve eyesight.


Diet and diet for presbyopia

Food is essential for eye care.

Proper digestion allows you to sleep better and have less irritated and tired eyes during the day.
There are two types of nutrition that have helped many patients to heal:

1. The blood type diet of Dr. D’Adamo / Mozzi .
According to this type of diet, diseases are caused by certain foods that can be harmful to people of a certain blood type.
Based on the blood type of each individual, there are harmful and other substances allowed.
Food allowed:

  • Vegetables are good for everyone.
  • You can eat meat, but people of type A and AB should avoid red meat.
  • Everyone can eat fish, but beware of the seafood.
  • One can eat fruit, especially in the summer, except those of type O  , that can have some symptoms.
  • Everyone can eat eggs.
  • Some nuts and seeds are recommended, but one should avoid overeating and be careful with peanuts.

There are certain foods that can often cause illness and symptoms in the patient:

  • Cold cuts, sausages and pork
  • Milk and dairy products
  • Gluten, people of type O and B should limit or avoid  other cereals, but may eat pseudocereals (quinoa, buckwheat and amaranth)
  • Chewing gum
  • Sugary and light drinks
  • Fried and smoked foods.

2. The vegan or crudivorous diet is based on raw, simple and natural foods.
This type of diet focuses on the speed of digestion. Foods that are digested quickly do not cause fermentation and intestinal putrefaction.
This way you can avoid diseases and sick blood.
The human body has a digestive system like that of frugivorous animals (chimpanzees, gorillas, etc.), so according to the vegan and basically raw diet we should eat the same foods.
The  natural medicine Lezaeta and hygienist are in favor of this diet and oppose any medication because the drugs are considered poisons.
Foods allowed are:

  • Fruit,
  • Raw vegetables,
  • Legumes,
  • Nuts,
  • Seeds,
  • Potato,
  • Avoid baking food, especially at elevated temperatures, and prefer steam cooking.


Exercises for presbyopia

Look at the sun for a few seconds, this exercise can be done early in the morning or late afternoon.
If the eyes are very sensitive to light, it is best to keep the eyelids closed. In this case you need to stay in the sun for a few minutes.

Here are some examples of eye exercises that improve vision:
All exercises should be repeated at least 20 times.

1. Look up as high as possible, then make the extra effort to look even higher. Now, look down as much as possible.
2. As in the previous exercise, but first looking to the right and then to the left.
3. Look to a higher point on the left, then look down to the right.
4. Draw a circle with the pupil in one direction and then the other.
5. Look at your nose and then relax.

Natural Remedies for Presbyopia

According to conventional medicine, we can help protect the eyesight by taking these precautions:

  • Have regular eye exams.
  • Check for chronic diseases that could contribute to vision loss, such as diabetes or high blood pressure .
  • Wear sunglasses.
  • Wear protective eyewear when practicing activities that may cause eye disease.
  • Wear the correction glasses.
  • Read with sufficient lighting.
  • Eat a healthy diet . Eat fruits, green leafy vegetables and other vegetables and vegetables.
    These foods contain high levels of antioxidants, such as vitamin A and beta carotene , and are also vital to keeping eyes healthy.
  • The Bates method . Dr. Bates noted that people with sight problems move their eyes less than people with normal eyesight. This, along with muscle fatigue, causes vision problems. The Bates method consists of a series of exercises based on moving, centralizing and relaxing the eyes.
