摘　　要：目的：探讨严重粘连性小瞳孔白内障超声乳化术的安全性及手术技巧。方法对26例（32只眼）粘连性小瞳孔白内障，术中采用透明角膜切口，散瞳后瞳孔直径（2．5±0．5）mm。以晶状体调位钩及chopper钩辅助，松解粘连，扩大瞳孔至4～5 mm，连续环形撕囊后进行原位白内障超声乳化吸除及折叠人工晶状体植入。结果术后3个月随访，术眼视力均较术前提高，其中视力≥0．5者20只眼（62．5％）。术后患眼瞳孔接近圆形或椭圆形，部分患者瞳孔直径较术前偏大。但其中2只眼再发部分后粘连，1只眼后囊少许破裂，仍植入人工晶状体，无人工晶状体明显偏位。结论采用上述技术不仅顺利完成小瞳孔白内障超声乳化术，且手术安全有效，视力恢复较好，保持或接近生理性圆，手术并发症相对减少。Objective To evaluate the cataract extraction and IOL implantation for the cataract with serious small adhesive pupil.Methods The case control study was conducted in 26 patients （32 eyes） with severe small adhesive pupil between October 2012 and September 2014.Small pupil was defined as diameter equal to or less than 2.5 mm after maxi-mal dilation.Corneal incision was made and lens position adjusting hook and chopper hook were used to relieve the adhe-sions so that the pupil diameter would return to 4~5 mm.Continuous curvilinear capsulorhexi, phacoemulsification and in-traocular lens implantation were then performed.Results During 3 months of follow up, visual acuity improved in all pa-tients and was better than 0.5 in 20 eyes （62.5%）.The pupils remained circular or nearly circular, and in some patients the diameter became slightly larger than that before the surgery.There was no dislocation of intraocular lens.Conclusion Relief of the small adhesive pupil before cataract surgeries ensures safety during the surgery and improves the visual acuity outcomes with fewer complications.
