We all use vision to enjoy the beauty 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 the computer, we do not spare our sight and often go to the doctor when serious ophthalmic problems begin.
Today, diagnoses such as myopia, farsightedness and astigmatism are known even to children. All these diseases are characterized by impairment of visual acuity. Depending on the situation and age of the patient, different 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 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 step forward in the field of ophthalmology, allowing you to restore visual acuity in just one day. It is 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, and therefore 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 sight.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, 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 variants of the standard Lasik procedure, which can sometimes be used for thin corneas.
Performing an operation
An 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. Consequently, the damage 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 are carried out by the patient at home independently.
Contraindications for surgical intervention
Vision correction with laser surgery is not performed on people under 18 and over 60 years old. 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 recovers very quickly after laser surgery. The patient should only follow the rules of eye hygiene, temporarily exclude physical activity. Complications of the laser procedure are minimized.
So, we discovered that vision restoration surgery allows achieving the best results in eliminating problems such as myopia, hyperopia, glaucoma, fibroids, and astigmatism. The vision correction procedure is quick, recovery and adaptation are painless. Even with advanced stages of diseases of the organs of vision, surgery works wonders. In this case, the patient is not exposed to general anesthesia, he does not feel discomfort before and after the operation.
And yet, better than any surgery is disease prevention. Therefore, it is necessary to protect vision and health in general from an early age.
