Kinds

Today in the ophthalmologic practice there are several methods of laser correction. This should include:

• Super Lasik.This technique is one of the most popular. Perform it taking into account the individual characteristics of the human body, so you can get pretty good results.
• Lasik.This is the basic technique. It does not take into account the individual features of the structure of the cornea, so its effectiveness is less.

Technique of Lasik

Perform such an operation in those clinics where there is no modern equipment.

• Femto Lasik.This type of laser operation involves cutting the cornea using a special femto-laser.
• Femto Super Lasik.The operation is performed similarly to the previous procedure, but only takes into account the individual features of the structure of the organ of vision.
• Presbye Lasik. Within the limits of laser vision correction, changes in the imaging of objects at close range are taken into account. The main task, which involves such an intervention - is to guarantee a person an excellent vision without glasses. Thus, he can see objects well at any distance from the eye.
• KFKIs a more painful method of correction. It is used only by those people who have contraindications to the rest of the manipulations.

The peculiarity of FRK is that the rehabilitation period lasts long and painfully. Additional recovery methods are required as special contact lenses.

• Epi-Lasik.The technique is rarely used, and it is used for patients with a thin cornea.

Indications for conduction

Super Lasik is used to correct defects that occurred after surgery on other excimer lasers. Femto Super Lasik is prescribed for vision correction with all the same diseases, but only this technique allows to restore the visual function even with a too thin cornea.

Process of procedure

Precise computer calculations are necessary before carrying out the operation. They need to be done for each individual case.Thus, it is possible to preserve the anatomical layers of the cornea.

The operation is carried out in several stages:

1. First stepinvolves the separation of the upper layers of the cornea with a shredder. It is performed by the doctor with an automatic microsurgical instrument, whose name is microkeratome. Thus, it is possible to open access to the middle layers of the corneal tissues. The duration of this stage is about 3 seconds, while the patient does not feel any pain at all.
2. Second phaseIt involves evaporation of the homogeneous inner layers of the cornea to the depth at which the cornea can receive the desired curvature.
3. The third stageassumes the return of the protective layer of the cornea to its place.
