 note = {Purpose：To analyze pre- and postoperative surgical events in cataract patients with small pupils who underwent cataract surgery.

Patients and methods：We reviewed the medical records of patients who underwent cataract surgery between January 2009 and May 2014 at Dokkyo Medical University Koshigaya Hospital. Surgery was performed by four experienced surgeons. We included 106 eyes from 83 patients with pupil sizes ＜5 mm in diameter who required iris retractors during the cataract surgery （small pupil group）. The control group was comprised of 447 eyes from 319 patients with pupil sizes ＞5 mm in diameter who did not require a mechanical dilatation of the pupil during cataract surgery. Pre- and postoperative intra- or extraocular surgical events were analyzed.

Results：Preoperative intra- or extraocular surgical events were observed in 36 eyes （34.0％） in the small pupil group and 72 eyes （16.1％） in the control group, with a significant difference observed for those who underwent laser iridotomy （P＜0.001） and trabeclectomy （P＜0.01）. Postoperative intra- or extraocular events were observed in 25 eyes （23.6％） in the small pupil group and 61 eyes （13.7％） in the control group, with significant differences observed for those who underwent the following procedures：trabeculectomy （P＜0.001）, sub-Tenon’s injection of triamcinolone acetonide （P＜0.001）, and posterior capsulotomy （P＝0.012）.

Conclusion：Cataract patients with small pupils often have pre- and postoperative intra- or extraocular surgical events. It should be recognized that cataract surgery is only one step in the treatment of cataract patients with small pupils.},
