Photorefractive keratectomy (PRK) is the treatment of the eyes surface.
PRK is a quick outpatient procedure in which the laser treatment is placed beneath the epithelium (the skin of the eye).
PRK is suitable for patients with mild to moderate levels of short-sightedness, long-sightedness and astigmatism. This can often be offered as an alternative to patients who are not suitable for LASIK.
After treatment, a bandage contact lens is fitted to reduce discomfort while the corneal surface heals. Vision recovery is not as quick as LASIK, the contact lens usually stays in place for a few days after treatment and vision gradually improves during this time. The PRK procedure is completely painless as the eye is anaesthetised using drops, however, some discomfort or grittiness will be experienced after treatment. This can be minimised by resting both eyes and taking the prescribed medication.
