Eyes wore either a 2-zone lens as a replacement for a −10 SV lens or for the entire treatment period (2-zone alone; data transposed from Table 3 for comparison). VCD change after an additional 5 days of 2-zone lens treatment is shown in parentheses. Mean VCD growth in untreated fellow eyes from days 10–15 is 0.21 ± 0.14 mm.
P < 0.05 comparing to 2-zone alone group.
