We all use sight to enjoy the beauties of the world, to perceive information and keep it in our memory. However, few of us think about how this unique mechanism works. In addition, working on the computer, we do not spare our eyesight and often go to the doctor when serious ophthalmological problems begin.
Today diagnoses such as myopia, farsightedness and astigmatism are familiar even to children. All these disorders are characterized by reduced visual acuity. Depending on the situation and age of the patient, various methods are used in the treatment of these pathologies: vitamin therapy, therapeutic exercises for the eyes, glasses. When such therapeutic methods fail, the doctor suggests the patient to undergo surgery to restore vision. What kind of operation is this? Let's find out together.
Types of surgery to restore vision
A few decades ago, humanity lacked the ability to eliminate complex vision problems. Today, the technological process has made a significant breakthrough in the field of ophthalmology, allowing you to restore visual acuity in just one day. It's about laser technology. Eye surgeries are performed using highly advanced laser equipment. There are several methods of laser vision correction. Let's see them in detail:
- Super Lasik- the most common operation today, which is carried out according to the individual parameters of each patient, so it gives the best results.
- Lasik- the basic method of vision correction. It does not take into account the individual characteristics of the patient's corneal structure.
- Femto Lasik- a technique that uses a special femto-laser to restore vision.
- Femto Super Lasik- the method is similar to the standard Femto Lasik, but is performed taking into account the individual characteristics of the patient's eye.
- Presby Lasik- the technique takes into account age-related changes in near vision in patients over 40 years of age, trying to correct it at all distances without glasses.
- PRK- the method is used for contraindications to standard procedures. For example, if the cornea is too thin.
- Epi-Lasik- one of the varieties of the standard Lasik procedure, which can sometimes be used for thin corneas.
Conduct surgery
The ophthalmologist surgeon removes the upper part of the cornea, after which the laser removes its inner part and returns the upper layer to its place. The operation is performed under local anesthesia, not under general anesthesia. As a result, the damage to the body is minimal. The patient feels great. After the operation, vision begins to recover after 2-3 days. Additional procedures to speed up the healing period, the patient leads home on his own.
Contraindications to surgery
Vision correction with laser surgery is not done on people under the age of 18 and over the age of 60. Also, this surgical intervention is contraindicated in the presence of such diseases in the patient as tuberculosis, diabetes, oncology. Laser correction is strictly not recommended for pregnant and lactating women.
Postoperative period
As we said earlier, vision is restored very quickly after laser surgery. The patient only needs to follow the rules of eye hygiene, temporarily exclude physical activity. The complications of the laser procedure are minimized.
Thus, we found that the operation to restore vision allows to obtain the best results in eliminating problems such as myopia, hyperopia, glaucoma, fibroids, astigmatism. The vision correction procedure is quick, recovery and adaptation are painless. Even with advanced stages of diseases of the organs of vision, the operation works wonders. In this case, the patient is not exposed to general anesthesia, does not experience discomfort before and after surgery.
Still, better than any operation is the prevention of the disease. Therefore, it is necessary to protect eyesight and health in general from an early age.
