摘　　要：目的观察白内障在小瞳孔下超声乳化联合人工晶状体植入术的临床疗效。方法采用超声乳化白内障摘出联合人工晶状体植入术治疗小瞳孔白内障38例（42眼）。青光眼术后虹膜后粘连14眼，陈旧性虹膜炎虹膜后粘连18眼，外伤导致瞳孔不能散大6眼，无外伤或虹膜粘连瞳孔不能散大者4眼（均≥71岁）。青光眼术后者采用透明角膜切口植入折叠人工晶状体，26眼采用巩膜隧道切口植人肝素表面处理的硬质人工晶状体，其余2眼也植入折叠人工晶状体。术后随访1。3个月。结果术前裸眼视力或矫正视力均≤0．3，术后1周裸眼视力或矫正视力≥0．6者31眼（73．8％），术后1个月≥0．6者34眼（81．0％），视力〉0．8者19眼（45．2％）。术后患眼瞳孔接近圆形或椭圆形者36眼，不规则者6眼。部分患眼瞳孔直径较术前偏大。结论在小瞳孔下行白内障超声乳化联合人工晶状体植入术手术复杂，手术技巧合理应用，并发症的预防和处理十分重要。Objective To observe the clinical effect of phacoemulsification through a small pupil and intraocular lens implantation. Methods Forty-two eyes of 38 patients accept phacoemulsification with intraocular lens implantation in treatment of small pupil cataract patients. Among them, 14 eyes with posterior syneehia after glaucoma surgery, 6 eyes with small pupil caused by trauma, 4 eyes without complications （All of the patients age≥71 ）. After glaucoma surgery by using foldable IOL implantation with clear corneal incision,26 eyes implanted heparin surface modified intraocular lens with straight scleral tunnel incision, other 2 eyes implanted foldable lens. Postoperative follow-up 1-3months. Results The number of the preoperative uncorrected visual acuity （UCVA） or best-corrected visual acuity （BCVA） ≤ 0.3 , Postoperativerly , the UCVA or BCVA ≥0.6 after the first week and first monthe were achieved in 31 eyes（73.8% ） and 34 eyes（81.0% ） 〉0.8 were achieved in 19 eyes（45.2% ） after the first week. the pupil nearly circular or oval were achieved in 36 eyes, irregular pupil were achieved in 6 eyes. Part of the patient＇s pupil is larger in diameter than the preoperative. Conclusion The operation of phacoemulsifieation through a small pupil and intraocular lens implantation is complicated , prevention and treatment of the complications is very important.
