摘　　要：目的观察虹膜后固定植入的ARTISAN虹膜夹持型人工晶状体在无晶状体眼中的临床应用效果。方法回顾性分析2010年1月至2011年4月间，在16例16只眼无后囊膜支持的无晶状体眼患者中，通过虹膜后固定植入ARTISAN虹膜夹持型人工晶状体，观察其术后视力、角膜内皮细胞密度、眼压等的变化。结果16例患者术前最佳矫正视力为0．46±0．19，术后裸眼视力为0．50±0．20，差异有统计学意义（P〈0．05）。16例患者术前角膜内皮细胞密度计数为（1914±151）个／mm2，术后1年为（1835±145）个／mm2，平均角膜内皮细胞丢失率4．1％。眼压未见明显改变。1例患者出现眩光不适症状。未见人工晶状体脱位等其他并发症。结论虹膜后固定虹膜夹持型人丁品状体的手术方式简单，术后视觉质量恢复好，并发症少，是目前治疗无后囊膜支持的无晶状体眼比较好的治疗方法。Objective To observe the clinical effect of the ARTISAN iris-clip intraocular lens im- planted through the retroiris fixation in aphakic eyes. Methods A retrospective analysis from Janu- ary 2010 to April 2011, aphakic patients in 16 cases （16 eyes） without qapsular support, through the implantation of ARTISAN iris-clip intraocular lens with retroiris fixed, and to observe their postopera- tive changes of visual acuity, corneal endothelium cells, intraocular pressure and other changes. Re- suits Sixteen patients with preoperative best corrected visual acuity was 0.46 4±0.19, postoperative uncorrected visual acuity was 0.50 ±0.20 （P 〈0.05）. Sixteen patients with preoperative corneal endo- thelial cell count （1914 ± 151）/mm2, 1 year after （1835± 145）/mm2, the average corneal endothelial cell loss rate was 4.1%. No significant changes in intraocular pressure after operation in all the cas- es. One case appeared symptom of glare after operation. No other complications such as intraocular lens dislocation were seen in all the cases. Conclusions This study suggests that retroiris fixed iris-clip intraocular lens insertion is a safe and simple surgery, and is beneficial in aphakia patients to acquired better visual acuity. The retroiris fixed iris-clip intraocular lens implantation seems to be an ideal treatment to the aphakia patients without capsular support in current.
