Objective: To identify neuroadaptation-related risk factors for persistent positive dysphotopsia (>6 months) following monofocal lens implantation. Design: Retrospective cohort study. Participants: Patients of an academic institution and a private practice in Saint Louis, Missouri. Inclusion criteria were adults with cataract extraction between January 2010 and April 2021 with monofocal intraocular lens implantation. Exclusion criteria included dementia, <20/40 acuity, visual pathway damage, visual field loss, and significant pathology causing photopsia. Methods: Participants were surveyed via telephone. Results: There were 385 participants (385 eyes), of whom 66 had persistent dysphotopsia (58 positive), 298 had none, and 21 had nonpersistent dysphotopsia. Among the 58 who had positive persistent dysphotopsia, mean Pseudophakic Dysphotopsia Questionnaire 6 (PDQ-6) score was 14.11 (SD, 8.46). There were no significant differences in sex or race. Migraine prevalence was greater among those with dysphotopsia (21.2%) than among those without (11.4%; p = 0.054). History of migraine was associated with an increase in PDQ-6 score of 2.76 points (p = 0.006). Six people in each group had Visual Aura Rating Scale (VARS) scores greater than zero. Mean VARS score was 0.48 for those with dysphotopsia and 0.14 for those without (p = 0.03). History of migraine or increased VARS score, younger age, and female sex were associated with lower satisfaction. Conclusion: History of migraine was associated with increased dysphotopsia severity and decreased patient satisfaction. Although further study with a larger sample size is warranted, these preliminary results highlight the potential of simple questions to individualize lens choice, reduce the risk of dysphotopsia, and improve patient satisfaction.
