PURPOSE To describe a technique for cataract surgery in eyes with small pupils that combines the use of the femtosecond laser and an iris expansion device, but without the use of corneal sutures and an ophthalmic viscosurgical device (OVD) at the time of laser application. METHODS A retrospective case series of three eyes with small pupils were operated by the same surgeon without a corneal suture and with removal of anterior chamber OVD prior to laser application. RESULTS Corrected distance visual acuity (CDVA) for 1 eye in a 70 year-old patient was 20/70 preoperatively and 20/20 thirty days postoperatively. CDVA for a second patient was 20/50 and 20/200 in the two eyes, which improved to 20/25 two months postoperatively in both eyes. There were no complications observed and the intraocular lens were well-centered. CONCLUSION The use of mechanical pupil expander rings is safe and practical in setting small pupils during femtosecond laser-assisted cataract surgery.

飞秒激光辅助小瞳孔白内障手术，使用不对齐的虹膜扩张环，无需粘弹性和角膜缝合。

目的 描述一种在小瞳孔中进行白内障手术的技术，该技术结合了飞秒激光和虹膜扩张装置的使用，但在激光应用时不使用角膜缝合线和眼科黏膜手术装置 (OVD)。方法 由同一位外科医生在激光应用前切除前房 OVD 的情况下，对三只小瞳孔的回顾性病例系列进行手术。结果 70 岁患者 1 只眼的矫正远视力 (CDVA) 术前为 20/70，术后 30 天为 20/20。第二名患者的两只眼睛的 CDVA 分别为 20/50 和 20/200，术后两个月改善为 20/25。没有观察到并发症，并且人工晶状体很好地居中。
