Abstract: To detect cataracts using retroillumination data from an autorefractometer and to compare these data across different cataract types. We recorded cataract type, best-corrected visual acuity (BCVA), and retroillumination data from an autorefractometer (COI. H (central opacity index height), COI. A (central opacity index area), and POI (peripheral opacity index)). The study included two groups: Group 1 (BCVA ≤ 0.5) and Group 2 (BCVA > 0.5). The National Eye Institute Visual Function Questionnaire-25 (NEI-VFQ-25) was administered to assess the impact of visual function on the quality of life in all patients. The study analyzed retroillumination data from cataracts and investigated the correlation between NEI-VFQ-25 results and BCVA. The study involved 258 eyes of 129 patients with cataracts aged 43–80 years. Significant differences were found in COI. H(mm), COI. A(%), and POI between groups (all p-values < 0.001). According to the ROC analysis, the AUCs for COI. H, COI. A, and POI values were 0.80, 0.74, and 0.79, respectively. COI. H and COI. A differed significantly among cataract types (both p < 0.001), whereas the difference in POI was marginal ( p = 0.045). The mean BCVA value was negatively correlated with retroillumination data. Retroillumination parameters showed moderate diagnostic value in cataract patients with reduced visual acuity. These parameters may provide useful additional information for assessing cataract-related visual impairment. Not applicable.
