Phacoemulsification and 1% atropine eye drops for treatment of antimetropic congenital microcoria associated with cataracts

ABSTRACT A rare case of bilateral congenital microcoria associated with antimetropia in a 47-year-old man is here described. The patient presented with a chief complaint of progressive vision loss in his right eye over the past five years. A slit-lamp examination and ultrasound biomicroscopy confirmed congenital microcoria and cataracts. Phacoemulsification was performed using an iris expansion device and the anterior capsule was stained using the “trypan down under” technique. Preoperative considerations, the surgical approach, and postoperative management are discussed.
