Aims: To investigate the incidence and risk factors for dry eye after pediatric strabismus surgery. Methods: Children aged 5 to 12 who underwent strabismus surgery were included in this single-center, prospective, cohort study. The ocular surface assessments were conducted 1 day before and 1 week, 4 weeks and 8 weeks after surgery. The main outcome measures are the incidence of dry eye after strabismus surgery and associated risk factors. Results: A total of 84 eyes (48 children) that underwent strabismus surgery were included in the study. The mean age at surgery was 7.21 years. The incidence of dry eye was 47.62% at 1 week, 10.71% at 4 weeks, 0% at 8 weeks after surgery. The preoperative tear Break-Up Time (BUT) was lower in the dry eye group than that in the nondry eye group (P ≤ 0.01). The univariate analysis showed that preoperative BUT was significantly associated with the incidence of dry eye after pediatric strabismus surgery (Odds Ratio [OR]: 0.647, Confidence Interval [CI]: 0.503~0.833, P ≤ 0.01). Conclusions: Dry eye commonly occurs after pediatric strabismus surgery. Tear film instability is more common than deficient aqueous tear production in patients with dry eye after surgery. Children with a low preoperative BUT are more likely to develop dry eye after strabismus surgery.
