Abstract:
This is the first literature report of a series of Zeiss iScription process wave guided spectacles (glasses) compared with conventional non-wave guided glasses. We designed a prospective pilot study of our initial clinical experience. Fifty patients with wavefront and fifty non-wavefront glasses were compared for lens changes made for comfort or visual clarity after initial manufacture and fitting. Minimum follow up was 90 days. Forty-six (92%) of the wavefront glasses required no modifications after initial delivery compared to 42 (86%) of non-wavefront glasses. There was a trend for conventional glasses to be returned more often than wavefront glasses but the difference was not statistically significant.
