Abstract Details

Purpose:

To evaluate early visual rehabilitation, postoperative pain, corneal epithelial healing and haze after TransPRK using the SmartPulseTechnology of SCHWIND Amaris (SCHWIND eye-tech-solutions GmbH, Kleinostheim, Germany).

Setting:

Emmetropia Mediterranean Eye Institute, Heraklion, Crete, Greece

Methods:

This was a comparative evaluation of a prospective cohort of myopic patients undergoing TransPRK with SPT (group 1), with one retrospective matched control group that underwent TransPRK only treatment (group 2). All cases had a follow-up of 3 months after the treatment. Postoperative examination included visual acuity and slit-lamp examination to evaluate the epithelial defect size and haze. Subjective evaluation of pain was also recorded postoperatively.

Results:

49 eyes of 25 patients in group 1 and 40 eyes of 20 patients in group 2 were enrolled. Visual rehabilitation of the patients was statistically significant faster in group 1 than in group 2 one day and one week postoperatively. Epithelial defect size was significantly smaller on postoperative days 1 and 2 for group 1 than in group 2. Regarding pain, there was no statistically significant difference between the groups. The haze level had no statistically significant difference between the groups at any point (1 week,1month and 3 months postoperatively) even though it was consistently lower in group 1.

Conclusions:

SPT modality provides promising results in the early postoperative stages after surgery. Visual rehabilitation and re-epithelialization were significantly faster at the early postoperative period in group 1 in comparison with group 2. The postoperative pain was not statistically significant different even though it tended to be less in group 1. Finally, no statistically significant difference occurred concerning the haze formation; however, it was consistently less in group 1.
