Abstract Background Secondary iris cysts are uncommon complication after cataract surgery. The reports of an iris cyst after conventional phacoemulsification surgery are scanty, let alone the iris cyst following femtosecond laser-assisted cataract surgery (FLACS). We herein report an unusual case of an iris cyst after an uneventful FLACS. Case presentation A 64-year-old man who was healthy underwent FLACS for a moderate cataract of his left eye. Shortly after surgery, he achieved 20/20 vision, but anterior bowing of temporal iris was noted on postoperative day 9 with a retro-pupillary iris cyst at temporal-inferior quadrant found after pupil dilatation. The cyst was confirmed by ultrasound bio-microscopy afterward. Four weeks later, argon laser cystotomy was performed, and the cyst disappeared 3 days later. The patient’s vision remained stable thereafter. Conclusion Although rare, secondary iris cyst may be one of the complications after FLACS. Argon laser cystotomy is effective in the management of post-FLACS iris cyst.
