Abstract Details


This study attempted to assess the impact of preoperative level of anxiety, pain perception, visual and refractive outcomes on patient's postoperative pain after laser subepithelial keratomileusis(LASEK) surgery.


Department of Ophthalmology, Bina Eye Hospital Research Center, Tehran, Iran


In this preliminary study patients who underwent lasek surgery for the first time from Binaafarin eye clinic, Tehran, Iran were enrolled. Post-operative pain at the 1st and forth day was assessed based on 11-point Numerical Analogue scale(NARS11). Additionally, the anxiety scale was completed using the self rating speilberger's state-trait anxiety questionnaire(STAI) questionnaire.


From 40 patients (52.5%men, the mean(SD) age: 26.7 (4.13) years), 40, 40, 17.5 and 2.5% of participants had severe, moderate, mild and no pain at the 1st post-operative day, respectively. Whereas, at the fourth post-operative day no patient reported severe pain. The mean of pain was higher at the first v.s forth post-operative day(5.77 (2.57) vs. 1.73 (1.72), P< 0.001). We observed significant correlation between anxiety trait scoring and pain scoring at the 1st post-operative day(r=0.402, p=0.01). Also, there was a significant correlation between cooperation of patient and pain(r=-0.331, p=0.037). Furthermore, no differences were found between pain and other factors


This study reports on the greater intensity of pain at the 1st post-operative day. Likewise, it allows patients and refractive surgeons to illustrate post-operative pain perception based on patient's psychological situation and cooperation irrespective of their gender. However, it needs further studies. FINANCIAL INTEREST: NONE
