PRK or photorefractive keratectomy is one of the laser vision correction methods. This operation was one of the methods of eye laser surgery, which replaced the radial keratectomy. This variant of the procedure has been studied, is very popular, and is used when other methods of correction are contraindicated for the patient.
Laser eye surgery is a high-tech way to correct a person’s vision. This variant of the operation is the most effective, as it can allow seeing well for a long time ahead. In addition, it is safe and comfortable for a person, since it has almost no negative consequences and practically does not cause discomfort. PRK is used to restore visual functions in hyperopia, myopia, and astigmatism.
This procedure can replace the wearing of glasses and contact lenses. Glasses can cause severe discomfort to a person while wearing them. They may not be convenient and it is enough just to break them, which in turn entails material losses. Lenses at the same time do not have these shortcomings, however, you need to allocate some time every day to put them on and take them off. In addition, while using them, it is possible to infect the eyes, which can result in serious unpleasant consequences. Laser correction will help you get rid of all these inconveniences and allow you to enjoy life with your vision.
The essence of the operation lies in the fact that with the help of a laser, the inner part of the cornea is destroyed and due to this, its curvature changes, and subsequently the light refractive ability. This method corrects a person’s vision and allows him to see better. Today, the PRK surgery is gentle and quite painless, but this was not always the case. Previously, this procedure was characterized by a long and unpleasant recovery period, during which the person experienced multiple painful sensations. In addition, it was impossible to do PRK eye surgery on both eyes at once, as it might not be safe. Now all the above disadvantages have been eliminated and the patient can feel much more comfortable during and after the operation. This effect was achieved, among other things, by using special lenses that are put on after the procedure.
The operation process is as follows:
· Before the start of the correction, a special anesthetic is instilled into both eyes of the patient, which allows you to feel as comfortable and calm as possible during laser eye surgery.
· After that, laser vaporization of the corneal tissue is performed. This action is performed according to the selected parameter, depending on the patient’s personal indicators and his refraction characteristics.
· A special contact lens is put on the eye, thanks to which the recovery period is as painless as possible. It must be in the eye for 5 days after the end of the correction.
· All the same actions listed above are carried out on the second eye
Let’s take a look at the main benefits of PRK:
