Photorefractive keratectomy

In this chapter, we have reviewed important aspects of PRK. A thorough understanding of the preoperative assessments, techniques, and postoperative management is essential to achieve satisfactory visual outcomes. Laser safety checks are mandatory. A well-functioning excimer laser with good optics is required. The surgeon must avoid any decentration or global tilt. All aspects of the technique must be performed with attention to detail. The postoperative management requires frequent follow-up visits and psychological reinforcement of a healing process that is not instantaneous. PRK is a procedure in evolution. Although the results today are impressive, the complications in the future will continue to decrease with changes in lasers, techniques, and pharmacological management.
