  • Title: Trans advanced surface laser ablation (TransPRK) outcomes using SmartPulseTechnology.
    Author: Aslanides IM, Kymionis GD.
    Journal: Cont Lens Anterior Eye; 2017 Feb; 40(1):42-46. PubMed ID: 27884617.
    Abstract:
    PURPOSE: To evaluate early visual rehabilitation, post-operative pain, epithelial healing and haze after transepithelial photorefractive keratectomy (TransPRK) using the SmartPulseTechnology (SPT) of Schwind Amaris (Schwind eye-tech-solutions GmbH, Kleinostheim, Germany). METHODS: This was a retrospective comparative evaluation of a cohort of myopic patients undergoing TransPRK with SPT (group 1), with one matched control group that underwent conventional TransPRK (group 2). All cases had a 6-month post-operative follow-up including visual acuity and slit-lamp examination. Subjective evaluation of pain was recorded post-operatively. RESULTS: 49 eyes of 25 patients in group 1 and 40 eyes of 20 patients in group 2 were enrolled. The patients' visual rehabilitation was significantly faster in group 1, one day and one week post-operatively (P<0.05). From one month onward there was no significant difference between the groups. The epithelial defect size was significantly smaller on post-operative days 1 and 2 for group 1 (P<0.05 in both cases). The pain score was also significantly less in group 1 (P<0.05). The haze level had no significant difference between the groups at any post-operative point (P>0.05). DISCUSSION: TransPRK using SPT provides promising results in the early post-operative period. Visual rehabilitation, re-epithelialization and pain were faster in the early post-operative period in group 1 in comparison with group 2. Haze formation was not significantly different between the two groups; however, it was consistently less in group 1.
