Abstract Details


We perform a retrospective no comparative study to analyse the astigmatic effectiveness with transepithelial photorefractive keratectomy (TransPRK) technique using small pulse technology (SPT) with static and dynamic cyclotorsion.


Aurelios Augenzentrum Recklinghausen Germany


TransPRK was performed with the AMARIS 1050 Hz laser system (SCHWIND eye-tech solutions, Kleinostheim, Germany), using an aspheric profile. We revised the refractive outcome of 500 consecutive myopic eyes after 4 months. From that group of eyes we analysed eyes with 2 or more diopters (D) of astigmatism (42 eyes). We used the subjective refraction and the postoperative topography after 4 months.


The mean treated cylinder was 2.9 D with a range till 5.25 D. After 4 months the postoperative mean cylinder was 0.4D with a range till 1.0D. In terms of safety no eye loss more than1 line of Snellen acuity. 79% of the eyes had a postoperative cylinder of 0.5D or less, 93% of 0.75D or less and 100% of 1 D or less. The axis error of the surgically induced cylinder vector was under 5 degrees in 79% of the cases and under 15 degrees in 100% oft he cases.


The TransPRK with SPT was effective and safe for myopic astigmatismsm.
