    Photorefractive keratectomy (PRK) is a corneal ablative procedure approved by the FDA in 1995 for correcting refractive errors.

  • 2

    Approximately 10-20% of patients may require a secondary PRK procedure due to residual myopia after the initial surgery.

  • 3

    Corneal topographic parameters significantly correlate with PRK stability, influencing the likelihood of needing retreatment.

  • 4

    Higher preoperative astigmatism, hyperopia, myopia, and older age are risk factors for requiring multiple PRK procedures.

  • 5

    This study aimed to identify clinical characteristics of patients needing multiple PRK surgeries to improve patient outcomes.
