Despite the fact that laser vision correction surgery has been performed for more than 30 years, patients still have a large number of questions and fears.. Specialists ophthalmologists told in detail about the course of laser vision correction surgery, so that confidence replaces your fears.

Diagnostics and tests. Before surgery, all patients undergo a mandatory comprehensive eye examination.. Only by the results of the research can we say whether you need an operation, whether you have any contraindications for it, and what method can be used to perform laser correction..

The procedure includes a complete examination of your visual system using high-precision devices and a consultation with an ophthalmologist.

The operation is performed only if you are healthy. There is no inflammation in the body, all diseases are cured, and chronic? in remission. In most cases, chronic diseases are not a contraindication to surgery, with the exception of diabetes mellitus.. In the presence of this disease, additional consultation with a specialist is necessary..

Therefore, analyzes are mandatory, they are a kind of admission to the operation..

The list of required tests includes:.

Blood for HIV.

Blood for hepatitis B and C.

Blood for syphilis.

blood sugar.

You can read more about how complex diagnostics are carried out in the network of Omicron clinics in the article on the website of the ophthalmological center.

OperationThe whole operation lasts about 15 minutes and is divided into several stages.

Eye preparation Drops are instilled into the eyes, which provide an anesthetic effect.. The sensitivity of the eyes is removed, only the sensation of touching the eyes remains..

Then the surface of the eyelids is treated with a special disinfectant solution.. A sterile napkin is applied around the eye, an eyelid dilator is inserted into the eye. Here lies the answer to one of the most common questions: what if I blink or my eye twitches during the operation? You just can't do it? eyelid expanders will not allow.

Corneal preparationThis stage depends on the chosen correction method:.

LASIK. This method allows you to cut the top layer of the cornea and bend it to the side.

The incision is made with a special contact instrument - a microkeratome..

During the incision, the patient should look at the flashing green light in the laser unit for 10–15 seconds.. The laser is centered in relation to the optical axis of the eye, and the eye is gently fixed with a microkeratome, like a small vacuum suction cup..

A person at this time can feel a touch and briefly lose the green light from sight..

FemtoLASIK. This is a more advanced and technologically advanced method..

The main feature of FemtoLASIK is that no top layer incision is required to prepare the cornea.. Instead, a femtosecond laser non-contact exfoliates the desired part, - says Alexander Padar, founder and CEO of the Omikron network of ophthalmological centers.

The patient does not feel anything during the operation of the femtosecond laser, but can also lose sight of the green light for a fraction of a second..

Laser exposure After the cornea is prepared, vision correction itself takes place directly. This process takes an average of about 20 seconds per eye.. During this time, the excimer laser vaporizes the corneal tissue. The whole procedure is fully automated: your data is entered into the laser system in advance, and the program accurately calculates the effect on the cornea. During the operation, the doctor necessarily monitors the indicators, dynamics and condition of the patient.

Everything you need from a patient? look at the light and do not move your eye. Many people think that if you accidentally look away, the entire course of the correction will be disrupted, or something terrible will happen.. You should not be afraid of this, if you look away, the protection will work and the laser will stop. When the gaze returns to the desired point, work will resume.

According to the patients of the Omicron clinic, there are no sensations during the laser vision correction itself, only the noise of the laser is heard.

Completion of the operation At the end of the operation, the incised flap is returned to its place and gently smoothed. No stitches required. Due to the fact that the flap is not completely cut off, and due to the natural properties of collagen, it fits evenly and tightly with the cut site.

The eyes are then flushed with saline and the lid dilators are removed..

The patient puts on dark glasses and leaves the operating room on his own. He is waiting for a doctor's examination, after which he can go home.

After surgery: The first time after surgery, the eyes will be very sensitive, redness, itching, dry eye syndrome and blurred vision are possible.. All this? norm variant. It is necessary to responsibly follow the recommendations of the doctor so that the rehabilitation process goes quickly and without complications.. On average, the rehabilitation period takes about a month..

Fear is based on the unknown. That is why we told you about every, even the smallest step of the operation..

And if you still have questions, you can always ask them to an ophthalmologist at a comprehensive vision diagnostics.
