PRK
PRK is a laser vision correction procedure used to correct refractive errors without creating a corneal flap. In this technique, the laser is applied directly to reshape the surface of the cornea.
In PRK, the superficial layer of the cornea is removed, and an excimer laser is then used to reshape the cornea according to the type and degree of refractive error. After treatment, a temporary bandage contact lens is usually placed on the eye to allow the corneal surface to heal over the following days.
After a specialized evaluation, PRK may be considered for correcting certain cases of myopia, hyperopia, and astigmatism. The final decision depends on the condition and thickness of the cornea, the eye prescription, and the individual characteristics of each patient.
In PRK, no corneal flap is created and the treatment is performed on the surface of the cornea. In Femto-LASIK, a very thin corneal flap is first created, and the excimer laser is then applied to the tissue underneath. Initial recovery after PRK is generally longer.
Before surgery, specialized eye examinations and the necessary corneal imaging are performed so that the ophthalmologist can determine whether PRK is suitable and plan the appropriate treatment.
Whether PRK is appropriate can only be determined after a specialized eye examination. Prescription stability, corneal thickness and shape, ocular surface health, and the absence of certain eye diseases are among the factors assessed before surgery.
Because the superficial corneal layer needs time to heal, patients may experience blurred vision, sensitivity to light, tearing, or discomfort during the first few days. The bandage contact lens is removed according to the doctor's assessment after the initial healing of the corneal surface, and visual quality gradually improves.
Regular use of prescribed eye drops, avoiding eye rubbing, protecting the eyes from contamination, and attending scheduled postoperative follow-up visits are important. Sunglasses may also be recommended during the healing period according to the doctor's advice.
The goal of PRK surgery is to correct refractive errors and reduce dependence on glasses or contact lenses. Treatment outcomes may vary between patients and depend on the initial condition of the eye, the degree of refractive error, and the corneal healing process.
When choosing between PRK, Femto-LASIK, SMILE, and other refractive correction procedures, the decision should not be based solely on the name of the procedure. Corneal structure and thickness, eye prescription, age, and overall eye health should be evaluated by an ophthalmologist.
No corneal flap is created during PRK. The superficial corneal layer is removed, and the refractive error is corrected with laser treatment on the corneal surface.
Visual recovery is gradual and varies between patients. Vision may fluctuate during the first few days and generally improves as the cornea heals.
In some patients, PRK may be considered as an option compared with certain flap-based procedures. However, corneal thickness is only one of several factors used in decision-making. A final assessment requires a detailed examination and evaluation of corneal mapping.
Both are surface refractive surgery procedures, but the way the corneal surface is prepared and the treatment steps are performed may differ. The appropriate procedure depends on the condition of the eye and the surgeon's evaluation.
To select the most appropriate vision correction procedure, the condition of the cornea and the overall health of the eyes should first be evaluated by an ophthalmologist.
