Scatter plots of endpoint relative RPR as a function of endpoint on-axis refractive errors for eyes wearing a 2-zone lens for 5 days after pretreatment with a −10 SV lens for 5 days. Solid circle: −5C/−10P. Open diamond: −10C/−5P (bottom panel). The mean RPR induced by −10 SV lens worn for 10 days was 1.58 ± 0.44 D.
