Area of Science:

  • Ophthalmology
  • Laser Surgery
  • Corneal Disease

Background:

  • Superficial corneal pathologies and irregularities can significantly impair visual acuity.
  • Existing treatments may be invasive or less effective for certain corneal conditions.

Purpose of the Study:

  • To review the fundamentals of phototherapeutic keratectomy (PTK).
  • To discuss indications, procedures, patient care, and potential complications of PTK.

Main Methods:

  • Review of current literature and FDA-approved indications for PTK.
  • Description of the phototherapeutic keratectomy surgical procedure.
  • Outline of preoperative and postoperative patient management.

Main Results:

  • PTK is approved for treating superficial corneal pathology and surface irregularities.
  • Indications include corneal dystrophies, degenerations, and scars affecting transparency.
  • PTK can be a viable alternative to corneal transplant surgery in select cases.

Conclusions:

  • Phototherapeutic keratectomy is an effective laser treatment for various corneal conditions.
  • Proper patient evaluation and postoperative care are crucial for successful outcomes.
  • Understanding PTK's indications and potential complications is essential for ophthalmologists.
