Predictive margins for number of mental health visits. Patients who underwent surgeries for both eyes were grouped into the following categories according to the time interval between surgeries: < 3, 3 to 6, 6 to 12, and > 12 months. The figure illustrates the marginal effect of first-eye surgery on the number of mental health consultations (1 year) with consideration of the time interval between first- and second-eye surgeries
