Adherence to treatment is one of the major challenges posed by modern medicine. Today, cataract is the leading cause of reversible blindness and visual disability. The study was aimed to assess adherence to timely surgical treatment in individuals with cataract. The data of the cross-sectional, population-based Ural Eye and Medical Study were assessed. Among 546 participants, there were 46.3% men and 53.7% women, 59.6% urban resudents, 40.4% rural residents. Their average age was 66.36 ± 9.47 years (40–88 years). Statistical data analysis was performed using the IBM SPSS Statistic software package. The findings showed that the lack of awareness of the disorder and low interest in surgery were the main factors, affecting the patients' motivation for cataract treatment. At the same time, the frequency of ophtalmology visits was inversely related to the patients' age (OR 1.24; 95% CI 1.04–1.49) and the duration of vision loss (OR 1.08; 95% CI 0.81–1.43), and directly related to the cataract diagnosis age (OR 1.20; 95% CI 1.04–1.38), the presence of ophthalmologist in the community clinic (OR 1.71; 95% CI 1.29–2.26), trust in the doctor (OR 3.62; 95% CI 3.02–4.35), ophthalmologist's explanation of the cataract complications and advanced treatment methods (OR 1.62; 95% CI 1.34–1.97). Understanding the main factors, contributing to low treatment adherence in patients with cataracts, would make it possible to optimize the measures to improve healthcare delivery to such patients, associated with the increased coverage of surgical treatment.
