In both study groups, the patients with SND clearly benefited from PTK. However, a significantly higher advantage for visual acuity and refraction was shown for the Schwind group compared with the Zeiss group. In contrast to the usual hyperopic effect of PTK in other diagnoses, PTK in SND showed a "myopic shift", which can be explained by the often midperipheral SND nodes and the associated asymmetric tear film pooling prior to surgery.
