Fig. 2

A Fraction of patients at each post-operative week with a spherical equivalent within 0.5 dioptres of the last follow-up spherical equivalent (circles). Squares denote the fraction of patients at each week with spherical equivalents within 0.5 dioptres that week, and all sequential weeks (i.e. all weeks for week 1, weeks 2–5 for week 2, etc.). B-E – Comparison of weekly spherical equivalent values with last follow-up value for each week. Diagonal lines demark border of stability criteria. Overlapping points appear as one. 3–7 points are outside the axis limits for the graphs
