We all use sight to enjoy the beauty of the world, perceive information and store it in memory. However, few of us think about how this unique mechanism works. Moreover, working with a computer does not spare our vision, and we often consult a doctor when serious eye problems begin.
Today, diagnoses such as myopia, hyperopia and astigmatism are known even to children. All these diseases are characterized by deterioration of visual acuity. Depending on the condition and age of the patient, various methods are used in the treatment of these pathologies - vitamin therapy, therapeutic exercises for the eyes, wearing glasses. If such therapeutic methods fail, the doctor recommends 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 was not able to eliminate complex vision problems. Today, the technological process has brought about a major breakthrough in the field of ophthalmology, making it possible to restore visual acuity in a single day. It's about laser technology. Eye surgeries are performed with highly advanced laser equipment. There are many 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.It's easy - 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 performed taking into account the individual characteristics of the patient's eyes.Presby Lasik - the technique takes into account the age-related changes in near vision in patients over 40 years of age and tries to correct it at all distances without glasses.PRK – the method is applied to contraindications to standard procedures. For example, if the cornea is too thin.Epi-Lasik - a type of the usual Lasik procedure, which can sometimes be used for thin corneas.
Conducting surgery
The eye doctor 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 damage to the body is minimal. The patient feels well. After the operation, vision starts to recover after 2-3 days. Further procedures aimed at speeding up the healing period are carried out by the patient independently at home.
Contraindications to surgical intervention
Vision correction with laser surgery is not performed by people under the age of 18 and people over the age of 60. In addition, 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 mentioned earlier, vision recovers very quickly after laser surgery. The patient only has to observe the rules of eye hygiene and temporarily exclude physical activity. Complications from the laser procedure are minimal.
So, we realized that the operation to restore vision allows to achieve the best results in eliminating problems such as myopia, hyperopia, glaucoma, myoma, astigmatism. The vision correction procedure is quick, recovery and adaptation are painless. Even in the advanced stages of diseases of the organs of vision, surgery works wonders. In this case, the patient is not exposed to general anesthesia, does not experience discomfort before and after the operation.
And yet, prevention of the disease is better than any surgery. This is why it is necessary to protect vision and health in general from an early age.
