PRK (Photorefractive Keratectomy) Lazer

PRK (Photorefractive Keratectomy) Lazer

PRK (Photorefractive Keratectomy) is a refractive surgical procedure used in eye surgery. In this procedure, the corneal surface is reshaped with a laser to correct vision defects such as myopia (nearsightedness), hyperopia (farsightedness), and astigmatism.

1. Objective:

  • PRK aims to correct the curvature of the cornea with a laser, allowing light to focus properly within the eye.
  • It is used to correct refractive errors such as myopia, hyperopia, and astigmatism.

2. Candidates:

  • Individuals with vision prescriptions, especially those with myopia, hyperopia, or astigmatism, can be candidates for PRK.
  • The procedure can be considered if eye health is suitable and other medical criteria are met.

3. Surgical Process:

  • The PRK procedure is generally performed under local anesthesia.
  • The epithelial layer on the surface of the eye is removed using a surgical instrument or an alcohol solution.
  • An excimer laser then reshapes the corneal surface, allowing light to focus properly inside the eye.

4. Recovery Process:

  • After PRK, the healing of the epithelial layer can take several days, during which temporary side effects such as discomfort, burning, and tearing may occur.
  • The full recovery process can take several weeks.
  • The patient should regularly use eye drops and medications prescribed by the doctor.

5. Advantages and Disadvantages:

  • Advantages:
    • There is a lower risk of flaprelated complications since no flap is created, unlike in procedures like LASIK.
    • PRK is more suitable for individuals with limited corneal thickness.
  • Disadvantages:
    • The recovery process may be longer and discomfort may be more pronounced.
    • Temporary blurred vision and discomfort may be more common.

6. Considerations:

  • PRK or similar laser surgery methods may not be suitable for every patient.
  • As with any surgical procedure, there are specific risks and complications.

7. Results:

  • PRK generally yields successful outcomes and can significantly improve patients’ vision quality.

If you are considering PRK or a similar laser surgery method, you should consult an eye doctor and obtain detailed information about a personalized treatment plan. It is important to seek professional advice before making decisions about your eye health and vision capabilities.
