Surface Lasik Process – prk

LASIK is a type of refractive surgery to correct myopia, myopia, and astigmatism

PRK was the first type of laser eye surgery to correct vision. Although the PRK process takes slightly longer than
LASIK eye surgery, PRK is still generally performed and offers more advantages than LASIK for some patients

The surface laser process works by reshaping the cornea using Exim laser, allowing the light to enter the eye to focus properly on the retina for a clear vision

How is surface LASIK performed?

The eye surgeon removes a central area of ​​the corneal epithelium with an alcohol solution, a surgical device or a surgical instrument.
After that, an excimer laser is used to accurately refine the corneal surface of the cornea.
This computer-controlled laser, which is highly specialized, will provide pulses of cold ultraviolet light that remove microspheres of tissue in a precise pattern and
then place a contact lens bandage On the cornea to help protect the eye,
the new epithelial cells grow in about four or five days, after which contact lenses are removed by the ophthalmologist.
Prk is used at most with people who want to progress to police or military colleges
because the advantage of surface iszik is that the sheds of the beam of Alzheimer’s on the surface of the cornea and waiting for the growth of corneal cells again, it was not detected in the examination of the war and others

Pre-operation tests

Check the bottom of the eye.
Measuring the pressure of the eye.
Draw a map of the cornea and measure its thickness.
Do not wear contact lenses before the operation for about a week.
Stop taking blood thinners.
Do not put cosmetics before the operation by 3 days.
