Safety
Change in spectacle-corrected visual acuity bar
graph Shows the change in spectacle-corrected
visual acuity from baseline to the postoperative
examination. This is the most commonly used
measure of safety, because it answers the
question If the result of refractive outcome is
not totally acceptable, can the patient put
glasses on again and see as well as they did
before surgery? A change of 1 line is within the
range of normal biological variability for
repeated measures, and therefore is not a
meaningful change. Reporting of a loss of more
than two lines is more important.

Predictability
Scattergram of attempted vs. Achieved
refraction The advantage of graph - presenting
the outcome of every eye, so that nothing is lost
in means or averages and outliers can be easily
identified.
