Abstract Details

Purpose:

In this study we aim to evaluate the level of postoperative pain in eyes undergone Refined TransPRK and then treated with Iran Regimen. The pain score is evaluated on the day of surgery and first, second, and third postoperative days. We also aim to explore the differences between the level of pain experienced in the right and left eyes and whether the differences in gender, level of education, and age of the patients affect the level of pain experienced by them.

Setting:

In this study 516 eyes of 258 patients undergone Refined TransPRK using the Amaris laser (SCHWIND eye-tech-solutions GmbH, Kleinostheim, Germany) in Bina Eye Hospital, Tehran, Iran and treated with Iran Regimen Postoperatively between years 2014 and 2019 were enrolled.

Methods:

All of the patients were asked to fill a questionnaire rating the level of post-operative pain in a scale of 0-10 on the day of the surgery and the first, second, and third postoperative days. The patients’ demographic data were also gathered using the aforementioned questionnaire. The data was analyzed using spss 22 software.

Results:

The age of the patients was 31.5 ± 7.6 (66.3% female and 33.7% male). The  pain score immediately after surgery was 5.48 ± 3.52 and 5.36 ± 3.54 in the right and left eyes respectively. There was no significant difference between right and left eyes. The pain score significantly decreased on the first postoperative day (4.45 ± 3.14 in the right eyes and 4.35 ± 3.11 in the left, p-value < 0.001 for both). The pain score subsided to a mean of 0.84 ± 1.77 and 0.66 ± 1.52 in right and left eyes respectively in the third postoperative day.

Conclusions:

This study shows using Iran Regimen following Refined TransPRK not only has the advantages of avoiding the use of mitomycin C, topical NSAIDs and steroids before removal of the lens, but also results in an acceptable level of post-operative pain which subsides significantly in the first and third postoperative days. Previous studies on Refined TransPRK and Iran Regimen have also shown epithelial healing process is completed in two days in 97% of the eyes, and in three days in all of them.Moreover we did not find any difference in the level of pain between the right and left eyes.
