To analyze pre- and postoperative surgical events in cataract patients with small pupils undergoing cataract surgery.
We reviewed medical records of patients who underwent cataract surgery between January 2009 and February 2014. The surgeries were performed by 4 experienced surgeons. We included 80 eyes of 60 patients with pupil sizes of less than 5 mm in diameter and who required iris retractors during the cataract surgery (small pupil group). The control group comprised of 99 eyes of 77 patients with pupil sizes of more than 5 mm in diameter and who required no mechanical dilatation of the pupil during cataract surgery. Pre- and postoperative intra- or extra-ocular surgical events were analyzed.
Preoperative intra- or extra-ocular surgical events were seen in 22 eyes (27.5%) in the small pupil group and 12 eyes (12.1%) in the control group (P = [Editor1] 0.0091, chi-square test), and the difference was significant for laser iridotomy (P = 0.0033). Postoperative intra- or extra-ocular events were seen in 20 eyes (25.0%) in the small pupil group and 12 eyes (12.1%) in the control group (P = 0.025); the differences were significant for the following procedures: trabeculectomy (P = 0.019), intravitreal injection of anti-vascular endothelial growth factor antibodies (P = 0.019), and sub-Tenon injection of triamcinolone acetonide (P = 0.039).<br />
Cataract patients with small pupils often have pre- and postoperative intra- or extra-ocular surgical events. Thus, it should be recognized that cataract surgery is only a step in the process of treatment in patients with small pupils during cataract surgeries.
