摘　　要：目的评价自制虹膜拉钩在小瞳孔白内障手术中的应用效果。方法回顾性分析2018年1月至8月,应用作者自制的虹膜拉钩对青光眼术后和葡萄膜炎等导致的瞳孔缩小的白内障32例(35只眼)的资料。所有患者均行超声乳化白内障吸除和人工晶状体植入术。术后随访3~6个月。结果35只眼术中均达到边长5.0~6.0mm的方形瞳孔,顺利完成连续环形撕囊和晶状体超声乳化手术。仅1只眼术中出现虹膜少量出血但未影响手术进行。术后瞳孔近圆形,直径3.0~4.0mm,对光反应正常或迟钝。术后视力均有明显提高。无后囊破裂、瞳孔撕裂或眼压升高等并发症发生。结论对小瞳孔白内障,手术中应用自制的虹膜拉钩,能够扩大瞳孔,获得良好的手术效果,拉钩制作方便、操作安全简单。Objective To evaluate the efficacy of application of self-made iris retractors in surgeries of cataract with small pupil. Methods The data of 35 eyes of 32 cases of cataract with miosis due to glaucoma surgery, uveitis and etc from Jan. 2018 to Aug. 2018 were analyzed retrospectively. All cases underwent phacoemulsification and intraocular lens implantation with self-made iris retractors. The patients were followed up for 3-6 months. Results All the 35 eyes achieved square pupils of 5.0-6.0 mm in side length during operation, and the continuous circular capsulorhexis and phacoemulsification were successfully completed. Only 1 eye had minor iris hemorrhage during operation, but it did not affect the surgery. The pupil was nearly circular with diameter of 3.0-4.0 mm after surgery. The pupillary light reaction was normal or sluggish. Visual acuity was significantly improved after surgery. No complication such as posterior capsule rupture, pupil tear, anterior chamber hemorrhage or elevated intraocular pressure occurred. Conclusion Application of self-made iris retractors for the treatment of cataract with small pupil can enlarge the pupil and obtain favorable results. The self-made iris retractors are easy to make and simple and safe to use.
