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.
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.
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.
继发性虹膜囊肿是白内障手术后少见的并发症。有关常规超声乳化白内障吸除术后发生虹膜囊肿的报道较少，更不用说飞秒激光辅助白内障手术（FLACS）后发生虹膜囊肿了。本文报告了一例 FLACS 术后不常见的虹膜囊肿。
一位健康的 64 岁男性左眼患有中度白内障，接受了 FLACS。术后不久，他的视力达到了 20/20，但在术后第 9 天发现颞侧虹膜前凸，瞳孔扩张后发现颞下象限有后发性虹膜囊肿。随后通过超声生物显微镜证实了该囊肿。4 周后进行氩激光囊切开术，3 天后囊肿消失。此后，患者的视力保持稳定。
虽然罕见，但继发性虹膜囊肿可能是 FLACS 后的并发症之一。氩激光囊切开术对治疗 FLACS 后虹膜囊肿有效。
