Here we report a case of surgical pupilloplasty in an adult with true polycoria. A 44-year old man was referred to our clinic with a best-corrected visual acuity (BCVA) of 0.5 diopters (D) in his left eye. Biomicroscopy revealed two pupils within a 2.5-mm central zone, with diameters of 1.2 and 1.1 mm. Both pupils had real iris sphincters and responded to light and chemical stimulation. Therefore, we surgically cut the bridge between the two pupils without any intraoperative or postoperative complications. One month after the surgery, BCVA had improved to 0.9 D, and the final pupil was almost round, measuring 2.7 mm in diameter.
