Area of Science:

  • Ophthalmology
  • Laser Surgery
  • Corneal Refractive Surgery

Background:

  • Excimer laser refractive surgery has demonstrated safety and efficacy over 20 years.
  • Surface ablation, or photorefractive keratectomy (PRK), is widely used for myopia, astigmatism, and hyperopia correction.

Purpose of the Study:

  • To review literature on surface ablation procedures.
  • To identify key factors for optimizing outcomes and minimizing complications in PRK.

Main Methods:

  • Literature review of surface ablation procedures.
  • Analysis of factors influencing PRK success and complications.

Main Results:

  • PRK generally yields satisfactory visual outcomes for most patients.
  • A small percentage of patients may experience complications such as corneal haze and regression.

Conclusions:

  • Optimal outcomes in PRK require adherence to specific procedural keys.
  • Minimizing complications like visual disturbances is achievable through established protocols.
