ClinConnect Summary

Photorefractive keratectomy (PRK) and laser-assisted in situ keratomileusis (LASIK) are two of the most widely used techniques of laser vision correction. However, one of the major disadvantages of the PRK technique is the pain experienced during 1 to 3 days after intervention.

Preliminary data on a limited number of patients tend to show a reduction of pain, tearing and discomfort in patients for whom a amniotic membrane was used under a therapeutic lens.
