Visual acuity of IAI switch patients. Compared to baseline, VA at the time of switch significantly improved (*p < 0.0001) from 59.4 to 66.7 letters. From the time of switch to 3 months, VA also significantly improved (*p < 0.0001) from 66.4 to 69.0 letters. After 3 months, VA was significantly improved compared to baseline (*p < 0.0001). In Year 3, data is aggregated from 88 patients and in year 4, data is aggregated from 58 patients
