Abstract Details


To evaluate the clinical data after TransPRK (transepithelial photorefractive keratectomy) using the smart pulse technology (SPT).


Aurelios Augenlaserzentrum, Recklinghausen, Germany


We use the AMARIS 1050 Hz laser platform (SCHWIND eye-tech-solutions, Kleinhostheim Germany) with SPT in a group of 40 consecutive myopic eyes with a range of -1 to -8 Dioptres (D) (mean -3.25D). We analyse the binocular UCVA (uncorrected visual acuity) 4 days after the surgery and UCVA and BCVA (best corrected visual acuity) after 3 months. In all cases standard examinations, pre- and postoperative corneal-wavefront analyses ocular-wavefront aberrometries were performed. We also compare the data in the early healing period with a previous consecutive group of 40 eyes treated without smart pulse technology.


The group of eyes with SPT had better binocular UCVA after 4 days 81% of eyes with visual acuity of 20/25 or better versus 21% in the group without SPT. In terms of safety no eye loose more than 1 line of Snellen acuity. The predictability was similar in both groups with 100% eyes +/-1 D after 3 months.


The TransPRK with SPT is a safe and effective surface ablation technique. The outcomes show that the incorporation of the smart pulse technology in the TransPRK gives us a quicker visual rehabilitation by creating a smoother corneal stromal surface.
