0:00:02and my name's are becoming the norm contented used to this paper on optical ray
0:00:07tracing guided lacing and the one you're follow-up
0:00:10previously but i was published on a prospective five was published on ray tracing lacing
0:00:16and the a comes at three models for patients with more than for the opposite
0:00:20my and all to more than two doctors of astigmatism
0:00:24and this paper we look at that same cold of patience not have one you're
0:00:28follow-up
0:00:29and we compare it to patients who had wavefront guided basic way for an optimized
0:00:34lace export partly guided leipzig for the same refracted errors
0:00:38and we look at uncorrected acuity base corrected acuity
0:00:42safety stability and predictability
0:00:45and if you look at the results will see that ray tracing is particularly good
0:00:49and the key reason why ray tracing is so good
0:00:52because the way that the calculation is the for the lies
0:00:56so with any normal procedure irrespective of how the diagnostics all is once the laces
0:01:02given that information the lace assumes that we are treating goals trends i model
0:01:07so it plans of three and four forty three the optical double curvature
0:01:10and it twenty four maybe excellent
0:01:13with the right tracing we optionally create the but if a model for that patient
0:01:18using their dimensions so we know with the excellent please note big k which is
0:01:22we know with a lens is inside the
0:01:25and using this information we can completely customise the treatment planning and this is a
0:01:30ray tracing his
0:01:31and one separated by you will see that ray tracing without using any algorithms aufnahmen
0:01:36trams lens of giving superior results to other of duration propose a been a i've
