Abstract: Objective To investigate the postoperative pain and corneal irritation after superficial corneal refractive surgery by different surgical procedures. Methods A total of 600 cases (1 200 eyes) of surface corneal refractive surgery were divided into 3 groups according to different operation methods as photorefractive keratectomy group (PRK group), laser epithelial keratomileusis group (LASEK group) and epipolis laser in-situ keratomileusis group (Epi-LASIK group). The pain index and corneal irritation among the three groups were compared. Results On day 1 after surgery, there was no statistical difference in the pain index and corneal irritation between PRK group and LASEK group, but there was statistical difference between Epi-LASIK group and the other two groups. On day 2 and 3 postoperatively, there was statistical difference between the PRK group and the other two groups, but there was no statistical difference between LASEK group and Epi-LASIK group. One day 5 after surgery, there was no difference among the three groups. Conclusion The pain after surface corneal refractive surgery is the major factor of postoperative discomfort for patients. Postoperative pain index and corneal irritation are different for different operation methods.

Key words: Pain, Photorefractive keratectomy, Laser epithelial keratomileusis, Epipolis laser in-situ keratomileusis
