Execution of the procedure

The operation is under local anesthesia. The specialist carries out the treatment of eyelids and eyelids with the help of an antiseptic. He can also drip antibacterial drops to prevent the development of the infectious process. To fix the eye, the eyelid expander is used.

The first stage of the operation involves the removal of the epithelium. For this, a laser is used. Then the process of evaporation of the cornea occurs.

This method requires the residual thickness of the cornea. To ensure that it fully fulfills its functions, its thickness will be 200-300 microns.

There are situations when you can refuse excising the epithelium. Then surgical intervention is faster and with a low risk of complications.

Postoperative period

In the first day after the operation, the patient is prescribed antibiotics and corticosteroids. This helps prevent the development of infection and inflammation. Beta-blockers can be used to prevent intraocular pressure.

Within a few days after correction, the patient should comply with the following recommendations:

1. To be in a darkened room.If the light is too bright, pain and eye pain may occur. It will irritate the cornea and prevent it from healing.
2. Do not touch the eye.
