Abstract Details

Purpose:

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

Setting:

Aurelios Augenlaserzentrum, Recklinghausen, Germany

Methods:

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.

Results:

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.

Conclusions:

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.
