Photorefractive keratectomy (PRK), commonly known as a laser vision correction procedure has recently proven itself in the treatment of eye correction. This is a simple eye surgery with laser and local anesthesia, which includes cataract treatment, contact lens implantation, glaucoma treatment, PRK refractive surgery, refractive lens replacement surgery and strabismus surgery, etc. Therefore, using this procedure, it is believed that most vision problems can be cured, but it is necessary to have a general understanding of the procedure, as well as its diseases and surgical procedures, before making the decision to correct the sight.
The procedure is processed into corneal tissue, so before surgery, the surgeon must first remove a thin, transparent protective layer on the cornea (known as epithelium) to expose corneal tissue. The surgeon then changes the shape of the cornea using laser technology, removing part of the tissue. Therefore, the ability to concentrate is restored. So, the achievement of the operation is obvious. A “dressing” contact lens will be implanted into the cornea to protect the eyes until the epithelium is restored and periodic drops are needed to keep the eyes moist. Usually 5-7 days are enough to restore the eyes.
After the operation, a frequent visit to the surgeon is necessary, every two weeks at the beginning and every two to three months, when the eye condition stabilizes. Thus, the kraff eye institute will be maximally protected from infection and accelerate the healing process.
Any surgical procedure is important for everyone, as well as vision correction. In addition to knowing the above information, you should also contact a professional eye health center that will provide you with comprehensive guidance, and in most cases photorefractive keratectomy (PRK) is always your preferred recommendation.
Summary
Photorefractive keratectomy, or PRK, is the first laser procedure to use excimer lasers to change the shape of the cornea. During PRK, some cells on the surface of the cornea, called corneal epithelium, are removed before treatment begins.
