A Multisite Longitudinal Investigation of Psychological Outcomes Following Cataract Surgery in India.

BACKGROUND: Systematic data on mental health issues among adults with cataracts are not available from India. This study explored the impact of cataract surgery on depressive and generalized anxiety (GA) symptoms in an adult Indian sample.

METHODS: A multicenter, prospective, longitudinal cohort study was conducted. Subjects were recruited from four tertiary eye hospitals to assess depression, GA, and associated risk factors. A follow-up survey was carried out at 6 ( n = 273, group 1), 12 ( n = 198, group 2), or 18 months ( n = 105, group 3) post-cataract surgery. Variations in the intensity of depression and GA were assessed using multiple classification analysis (MCA).

RESULTS: A total of 576 patients completed both baseline and follow-up assessments. The mean (SD) depression score was 25.6 (8.5) before surgery and 8.6 (7.7), 9.9 (7), and 9.8 (6.8), respectively, post-surgery for the three groups on the Center for Epidemiologic Studies Depression scale (CES-D). The mean GA score was 6.7 (4.2) at baseline and 1.1 (2.3), 1 (1.8), and 0.6 (1.3) after surgery on the Generalized Anxiety Disorder scale (GAD-7). MCA showed that factors with the highest impact on the mean change scores for both depressive and GA symptoms were restoration of vision post-surgery ( β = 0.381 and 0.185) in group 1, regaining functional independence and female sex in group 2 ( β = 0.192 and 0.23), and the presence of ocular comorbidities in the fellow eye ( β = 0.36 and 0.315) in group 3.

CONCLUSION: Mental health symptoms improved significantly post-cataract surgery across the three groups. The urgent need to invest in strategies that enable early cataract case detection and treat ocular anomalies in the fellow eye is highlighted.
