We all use sight 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. In addition, working on a computer, we do not spare our vision and often go to the doctor when serious ophthalmic problems begin.
Today, diagnoses such as myopia, farsightedness and astigmatism are familiar even to children. All these diseases are characterized by impaired visual acuity. Depending on the situation and the age of the patient, different methods are used to treat these pathologies - vitamin therapy, therapeutic exercises for the eyes, wearing glasses. When such therapeutic methods fail, the doctor suggests that the patient undergo an operation to restore vision. What kind of operation is this? Let's figure it out together.
Types of operations to restore sight
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, which allows you to restore visual acuity in just one day. It's about laser technology. Eye surgeries are performed with highly modern laser equipment. There are several different methods of laser vision correction. Let's look at them in detail:
Super crawler - the most common operation today, which is performed according to the individual parameters of each patient, which is why it gives the best results.Lasik - the main 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 standard Femto Lasik, but is performed taking into account the individual characteristics of the patient's eye.Presby Lazik - 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 in case of contraindications for standard procedures. For example, if the cornea is too thin.Epi-Lasik - a variation of the standard Lasik procedure that can sometimes be used for thin corneas.
Conducting an operation
The ophthalmic surgeon removes the top part of the cornea, then 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, the 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 carries out independently at home.
Contraindications for surgical intervention
Vision correction with laser surgery is not performed on persons 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, after laser surgery vision recovers very quickly. The patient only needs to observe the rules of eye hygiene, temporarily exclude physical activity. Complications from the laser procedure are minimized.
So, we found out that vision restoration surgery allows you to achieve the best results in eliminating problems such as myopia, farsightedness, glaucoma, fibroids, astigmatism. The vision correction procedure is quick, recovery and adaptation are painless. Even at an advanced stage 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 the operation.
Still, better than any surgery is the prevention of the disease. That is why it is necessary to protect vision and health in general from an early age.
