Transepithelial photorefractive keratectomy (PRK) did not significantly reduce surgical time compared to alcohol-assisted PRK. While variance in surgical time was lower, laser treatment duration and breaks increased, showing no overall time-saving benefit for refractive surgery.

Area of Science:

  • Ophthalmology
  • Refractive Surgery
  • Corneal Surgery

Background:

  • Photorefractive keratectomy (PRK) is a common refractive surgery procedure.
  • Transepithelial PRK offers a potentially faster alternative to traditional alcohol-assisted PRK.
  • Optimizing surgical time is crucial for efficiency in refractive surgery suites.

Purpose of the Study:

  • To evaluate the time efficiency of transepithelial PRK compared to alcohol-assisted PRK.
  • To analyze the impact of Streamlight™ transepithelial PRK on surgical workflow in surface corneal ablations.

Main Methods:

  • A comparative study matching 105 patients undergoing transepithelial PRK with 105 patients undergoing alcohol-assisted PRK.
  • Refractive surgeries performed using the Alcon WaveLight® EX500 excimer laser.

  • Analysis focused on total surgery time, laser treatment duration, and breaks during laser application.

    • Main Results:

    • No significant difference in mean total surgery time between transepithelial PRK (349.46 ± 47.83 s) and alcohol-assisted PRK (354.93 ± 137.63 s).
    • Significantly lower variance in surgical time for transepithelial PRK (p < 0.001).
    • Increased laser treatment duration (41.78 ± 17.2 s vs. 8.48 ± 6.12 s) and more breaks (0.95 ± 0.63 vs. 0.53 ± 0.88) were observed in the transepithelial PRK group.

    Conclusions:

    • The introduction of transepithelial PRK did not yield significant time savings in the refractive surgery suite.
    • While reducing time variability, transepithelial PRK increased laser application time and intraoperative breaks.
