We all use vision to enjoy the beauties of the world, perceive information and store it in memory. However, few of us think about how this unique mechanism works. In addition, working at a computer, we do not spare our eyesight and often go to the doctor when serious ophthalmological problems begin.
Today, such diagnoses as myopia, hyperopia and astigmatism are familiar even to children. All of these conditions are characterized by impaired visual acuity. Depending on the situation and age of the patient, different methods are used in the treatment of these pathologies - vitamins, therapeutic exercises for the eyes, wearing glasses. When these therapeutic methods fail, the doctor suggests that the patient undergo surgery to restore vision. What type of operation is it? Let's find out together.
Types of surgery to restore vision
A few decades ago, mankind did not have 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. This is laser technology. Eye surgeries are performed using state-of-the-art laser equipment. There are several different methods of laser vision correction. Let's look at them in detail:
- Super LASIK- the most common operation today, which is performed depending on the individual parameters of each patient, therefore it gives the best results.
- LASIK- the basic method of vision correction. It does not take into account the individual characteristics of the structure of the patient's cornea.
- Femto-Lasik- a technique that uses a special femto-laser to restore vision.
- Femto Super Lasik- the method is similar to standard Femto Lasik, but is carried out 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, 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.
Surgery
The eye surgeon removes the upper part of the cornea, after which the laser removes its inner part and puts the upper layer back in place. The operation is performed under local anesthesia and not under general anesthesia. As a result, damage to the body is minimal. The patient feels well. After the operation, vision begins to recover after 2-3 days. Other procedures to speed up the recovery period, the patient performs alone at home.
Contraindications to surgery
Vision correction by laser surgery is not performed on people under the age of 18 and over the age of 60. Also, this surgical intervention is contraindicated in the presence of diseases such as tuberculosis, diabetes, oncology in the patient. Laser correction is strictly not recommended for pregnant and breastfeeding women.
Postoperative period
As we said before, 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 have discovered that the vision restoration operation allows you to obtain the best results by 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 visual organs, the operation works wonders. In this case, the patient is not exposed to general anesthesia, does not feel discomfort before and after surgery.
And yet, better than any operation is the prevention of disease. Therefore, it is necessary to protect vision and general health from an early age.
