The long-term psychosocial impact of correction surgery for adults with strabismus

摘要

In the recently published study by Jackson et al,1 the authors compare the impact of strabismus surgery in adults over time. Using a repeated measures design, data were collected from all participants at 6 weeks preoperative (Tl), 3 months (T2) and 18 months (T3) postoperative appointments. The authors used a one-way analysis of variance (ANOVA.) to compare changes between the three time points; however, this is inappropriate because it assumes that the measurements taken from the same person over time are independent.
