We all use sight to enjoy the beauties of the world, to perceive information and to store it in our memories. However, few of us think about how this unique mechanism works. In addition, when working at the computer, we do not spare our eyesight and often go to the doctor when serious ophthalmological problems begin.
Diagnoses such as myopia, hyperopia and astigmatism are now familiar even to children. All of these ailments are characterized by impaired 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, wearing glasses. When such therapeutic methods fail, the doctor suggests the patient to undergo surgery to restore vision. What is this operation? Let's find out together.
Types of operations to restore vision
A few decades ago, humanity was unable to eliminate complex vision problems. Today, the technological procedure has made a significant breakthrough in the field of ophthalmology and allows you to restore visual acuity in just one day. It's about laser technology. Eye operations are performed with state-of-the-art laser equipment. There are different methods of eye laser correction. Let's look at them in detail:
- Great Lasik- the most common operation today, which is carried out according to the individual parameters of each patient and therefore 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 it 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 old and tries to correct them at all distances without glasses.
- PRK– the method is used in the case of contraindications to standard methods. For example, if the cornea is too thin.
- Epi Lasik- one of the variants of the standard Lasik procedure, which can sometimes be used for thin corneas.
perform surgery
The ophthalmologist removes the top part of the cornea, after which the laser removes the inner part and puts the top layer back in place. The operation is performed under local anesthesia, not general anesthesia. Accordingly, damage to the body is minimal. The patient feels great. After the operation, vision begins to recover after 2-3 days. Other procedures to speed up the recovery period are carried out by the patient himself at home.
Contraindications for surgical intervention
Vision correction with laser surgery is not performed on people under 18 and over 60 years of age. This surgical intervention is also 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 have already said, vision recovers very quickly after laser surgery. The patient just needs to follow the rules of eye hygiene, temporarily exclude physical activity. Complications from the laser procedure are minimized.
So, we found that vision restoration surgery allows you to get the best results in getting rid of such problems as myopia, hyperopia, glaucoma, fibroids, and astigmatism. The vision correction procedure is quick, and recovery and adjustment is painless. Even with advanced diseases of the organs of vision, the operation works wonders. In this case, the patient is not subjected to general anesthesia and does not experience any discomfort before and after the operation.
And yet prevention of the disease is better than any surgery. Therefore, it is necessary to protect vision and health in general from an early age.
