We all use vision to enjoy the beauties of the world, to perceive information and store it in memory. However, few of us think about how this unique mechanism works. Moreover, working at a computer, we do not spare our eyesight, and often go to the doctor when serious ophthalmological problems begin.
Today, diagnoses such as myopia, hyperopia and astigmatism are 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 that the patient undergo surgery to restore vision. What kind of operation is this? Let's figure it out together.
Types of surgery to restore vision
A few decades ago, humanity 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. It's about laser technology. Eye surgeries are performed using highly advanced 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 according to 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 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 old, 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.
Conducting surgery
The ophthalmologist surgeon removes the upper part of the cornea, after which the laser removes its inner part and returns the top layer to its place. The operation is performed under local anesthesia, not general anesthesia. Accordingly, harm to the body is minimal. The patient feels great. After the operation, vision begins to recover after 2-3 days. Further procedures to speed up the recovery period, the patient conducts at home on their own.
Contraindications for surgical intervention
Vision correction with laser surgery is not performed on people under 18 and over 60 years of age. 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 after laser surgery very quickly. The patient only needs to follow the rules of eye hygiene, temporarily exclude physical activity. Complications from the laser procedure are minimized.
So, we found out that the operation to restore vision allows you to achieve the best results in eliminating problems such as myopia, hyperopia, glaucoma, fibroids, astigmatism. The vision correction procedure is quick, recovery and adaptation is 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 experience discomfort before and after surgery.
And yet, better than any operation is the prevention of the disease. Therefore, it is necessary to protect vision and health in general from an early age.
