We all use vision 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 computers, we don't keep an eye on our eyesight and often go to the doctor when serious eye problems start.
Today, diagnoses such as nearsightedness, farsightedness, and astigmatism have become familiar even to children. All of these diseases are characterized by impaired vision. Depending on the condition and age of the patient, different methods are used in the treatment of these pathologies - vitamin therapy, therapeutic eye exercises, glasses. When such treatments fail, doctors recommend surgery to restore vision. What kind of activity is this? Let's explore it together.
Types of surgery to restore vision
A few decades ago, humanity was incapable of eliminating complex vision problems. Today, the technological process has made a significant breakthrough in the field of ophthalmology, allowing you to restore your vision in just one day. It's about laser technology. Eye surgeries are performed using advanced laser equipment. There are several different methods of laser vision correction. Let's look at them in detail:
- Super Lasik- a most popular surgery today, performed according to the individual parameters of each patient, so it gives the best results.
- Lasik- basic vision correction methods. It does not take into account the individual features of the patient's corneal structure.
- Femto Lasik- a technique that uses a special femto laser to restore vision.
- Femto Super Lasik- the same method as the standard Femto Lasik, but carried out taking into account the individual characteristics of the patient's eyes.
- Presby Lasik- the technique takes into account age-related changes in near vision in patients over 40 years of age, attempting to correct at all distances without glasses.
- PRK— the method used for contraindications to standard procedures. For example, if the cornea is too thin.
- Epi-Lasik- one of the styles of the standard Lasik procedure, which can sometimes be used for thin corneas.
Performing surgery
The ophthalmologist removes the upper part of the cornea, then the laser removes its interior and returns the top layer to its place. The surgery is performed under local anaesthesia, not under general anaesthesia. Accordingly, the harm to the body is minimal. Patient feels great. After surgery, vision begins to recover after 2-3 days. Follow-up procedures to speed up the recovery time, patients conduct themselves at home.
Contraindications for surgical intervention
Vision correction with laser surgery is not performed on people under 18 years of age and over 60 years of age. In addition, this surgical intervention is contraindicated in the presence of diseases such as tuberculosis, diabetes, oncology. Laser correction is not recommended at all for pregnant and lactating women.
Post-operative period
As we said earlier, vision is restored after laser surgery very quickly. The patient only needs to adhere to the rules of eye hygiene, temporarily excluding physical activities. Complications from the laser procedure are minimized.
So we found that vision restoration operation allows you to achieve the best results in eliminating problems such as nearsightedness, farsightedness, glaucoma, fibroids, astigmatism. The vision correction process is quick, and recovery and adaptation are painless. Even with advanced stages of diseases of the organ of vision, the operation works wonders. In this case, the patient does not need general anesthesia, does not feel discomfort before and after surgery.
And yet, better than any activity is disease prevention. Therefore, it is necessary to protect eyesight and general health from an early age.
