Refractive surgery for myopia (LASIK and LASEK)
This therapy allows correcting myopia by reshaping the curvature of the cornea.
The different methods of refractive surgery are:
LASIK (Laser-Assisted in situ Keratomileusis)
The LASIK technique is an operation in which an ophthalmologist makes a thin circular incision that extends to a part of the cornea.
Then the surgeon removes the central layers of the cornea to flatten the dome shape.
This type of surgery is also done to correctastigmatism or farsightedness .
The surgeon lifts a flap on the corneal epithelium.
The surgeon uses a laser to reshape the outer layers of the cornea and flatten the curvature; then repositions the epithelial flap.
To facilitate healing, it is necessary to wear a contact lens for several days after surgery.
Photorefractive keratectomy (PRK)
This procedure is similar to LASEK, but the surgeon removes the corneal epithelium.
It develops again naturally, adapting to the new shape of the cornea.
The PRK involves the application of a protective contact lens for 3-4 days after the operation.
Phakic intraocular lenses (IOLs)
These lenses are surgically implanted in the eye, in front of the lens.
They may be an option for people with moderate or severe myopia.
Intraocular lens implants are not currently considered a traditional treatment option.
All surgeries have a certain degree of risk.
The possible complications of these operations are:
- Infections ,
- Corneal Scars,
- Blurred vision at a distance,
- Loss of vision ,
- Visual aberrations (eg, see halos around lights at night).
Testimony of a patient undergoing PRK surgery
Patient with severe myopia (operated in 2006)
There are exams to be performed in the clinic a few days before the operation:
- Consultation to control the eye fundus with eyewash
- Pachymetry to know the thickness of the cornea
Anyone who wears contact lenses should stop using them a few weeks before.
I did not stop taking medication because I did not take any medication anymore.
On the day of surgery I could not use perfumes and had to be fasting.
Surgery is very brief. First the doctor puts on the anesthetic and lets it act; the total duration is half an hour.
I was only 10 minutes in the operating room.
First, the doctor monitors the heartbeat with the instrument applied to the finger and then applies the ocular retractor.
The doctor places eye drops. Then it is necessary to wait because it should apply more drops after a few minutes. The eye drops are applied about 3 times.
Then I went into a room with a dentist-type chair, but in which the patient lies completely down.
The doctor holds his head in his hands and a technician activates the laser.
It is necessary to look at a red lightthat it does not move, but I had the feeling that it moved.
If you look at another point, the laser stops working.
In the first part of the operation you feel a lot of pain : the doctor scratches the cornea and it is painful.
After that, the laser is powered for about 1/2 minutes.
Then the doctor applies the protective lens which should be kept for about a week and does not allow to see well because it collects the tears, eye drops and dead skin cells.
The pain is strong, but the doctor prescribes a therapy with anesthetic eye dropsand disinfectant. It is also necessary to take antibiotics and medication for pain.
After the surgery
The pain in the postoperative lasts one day, it is strong and I had the sensation of a foreign body in the eyes and tearing .
I could not take a shower or wash my hair in the postoperative because chlorine is a healing and could be a problem if it entered the operated eye.
At the clinic where I was operated on do not do surgery on both eyes simultaneously.
The second surgery was unsuccessful and I had to wait a few months to get back to work .
Anisometropia was created, that is, I could see very well with one eye (10/10), but the other one had gotten worse.
There was a visual diversity that could not be corrected.
There are no glasses that allow you to see this problem.
After six months, I repeated the surgery on the eye that still had the vision problem.
After the third surgery I waited 7/10 days to get back to work.
Certainly I would refine the operation, however in another clinic and with more recent techniques.
The effect of the surgery lasted for several months, but my myopia was very strong and therefore it was not possible to get a 10/10 result.
After a year I had to correct the defect with glasses, but I went from 3/10 to 7.5 / 10 with the surgery.
The Side Effects of Surgery
For a brief period after surgery I became a hyper-meter.
Other effects that can be attributed to surgery are dry eye and, therefore, low tolerance to contact lenses. In addition, dryness also occurs at night and in the morning it is difficult to open the eyes; When I can open them I feel a lot of pain.
The doctor prescribed the application of a gel for this side effect, but did not give good results.
There is a trick to being able to open your eyes glued in the morning: it is the rotation of the eyes to one side, and it is much easier.
The night visionis a problem, in my case because I have dilated pupils and even before the operation I had difficulties at night to evaluate the distance of the luminous objects.
In the street I can not judge how far the car is in front of me. If a pedestrian crosses between me and the other car, I might not be able to see it.
Results of surgery for myopia
Generally, the results of the three techniques are good.
Although it is not always possible to completely cure myopia, about 9 out of 10 people have a considerable improvement.
Who can not undergo laser surgery for myopia?
Patients younger than 21 years should not undergo refractive surgery because the view should still stabilize and it would be dangerous to alter the structures of the eyes at this stage.
The ophthalmologist should check prescriptions for contact lenses or glasses to confirm that vision has not changed significantly in the past two years.
Laser surgery may not be appropriate in the following situations:
1. Diabetes – This disease can cause abnormalities in the eyes that may be aggravated by surgery.
2. Pregnancy or breastfeeding – the body has hormones that cause slight fluctuations in sight and focusing, making surgery very difficult.
3. Diseases that affect the immune system, such as HIV or rheumatoid arthritis , affect the ability to recover after laser operation .
4. Other eye diseases such as glaucoma (a disease that can cause blindness) or cataracts (the lens hardens and becomes cloudy).
Natural Remedies for Myopia
Diet and nutrition
According to natural hygiene, eye diseases depend on toxemia (accumulation of toxins in the body and blood).
If the patient changes his diet and lifestyle can improve greatly, until he has normal vision.
The recommended diet is vegan and tends to be raw .
Drawing on Shelton’s experience at his fasting clinic, there are people who have recovered their vision completely and forever after a fast .
The Bates method for curing myopia. Dr. Bates, of the New York Eye Infirmary, made a great discovery in his research on the eye. He discovered that most eye diseases can be cured for good.
How did Dr. Bates make this discovery?
He discovered that when eyes are not under stress they can have perfect vision.
But as soon as the eyes become tense and tired , problems occur.
Through his research, Dr. Bates found that byregularly exercising for the eye muscles, vision returns to normal.
This is because muscle tension disappears and vision returns to normal.
Dr. Bates has tested thousands of patients with surprising results.
There are many different eye exercises that can be done
Here are some of them:
- Concentrate on the relaxation of the eyes . Move your eyes back and forth, up and down. Repeat 6 times.
- Sitting on a chair; Rub your hands until they are warm.
It is now necessary to close your eyes and cover them with warm palms.
Do not put pressure on the eyes.
Do not cover your nose.
It is important that light rays do not enter the eyes through the space between the fingers.
Repeat this exercise for 3 minutes.
- Focus on a distant object about 40 m for 15 seconds.
Then slowly orient your eyes toward a nearby object, about 10 m away.
This exercise should only be done with the eyes without moving the head.
Repeat 5 times.
- Close your eyes tightly for 5 seconds. Then keep them open for 5 seconds.
Repeat this procedure about 8 times.
- Hot compresses : wet a piece of flannel or a small towel with hot water.
Twist and cover eyes slightly. This effectively relaxes the eye muscles.
- Massage the eyelid : close your eyes and do a very gentle massage with circular motions for 1-2 minutes.
To improve eyesight, this exercise should be done regularly.
Visual re-education with the De Angelis
method The De Angelis method, known as the Power Vision System, is based on specific exercises that address the causes of myopia.
According to De Angelis, myopia is caused by prolonged hyperaccommodation, that is, an adaptation mechanism that occurs when the eye often works at a short distance, losing visual acuity from afar.
The movements performed aim to relax the ocular muscles and avoid stress due to hyperacomodation of the ciliary muscle.
