摘　　要：目的观察Artisan虹膜夹持型人工晶状体(IOL)治疗无晶状体眼的临床疗效及手术并发症。方法选取接受Artisan虹膜夹持型IOL植入术的无晶状体眼患者13例(13眼),比较患者手术前后裸眼视力、最佳矫正视力和眼压变化,裂隙灯显微镜观察术后角膜水肿、前房闪辉、IOL位置和虹膜情况并行角膜内皮细胞计数。结果术后随访平均2年,裸眼视力及最佳矫正视力超过0.5的有5只眼(38.5%)和6只眼(46.2%),手术前后眼压无明显变化,术后随访角膜无明显水肿,晶状体位置未见明显偏移,前房无明显炎症反应,平均内皮细胞丢失率为10.1%。术中有2例合并虹膜损伤穿孔,有2例发生虹膜出血,但均在术后短期内吸收。术后随访1例IOL脱位,予重新手术固定。随访未发现黄斑囊样水肿。结论 Artisan虹膜夹持型IOL植入术是一种安全有效的治疗无晶状体眼的方法,手术操作相对简单,组织损伤相对较小,并发症少,术后视力提高较为显著。Objective To observe the clinical effects and surgical complications of Artisan iris-fixated intraocular lens （IOL） implantation for the treatment of aphakic eyes. Methods Thirteen patients （thirteen eyes） with aphakic eyes who received Artisan IOL implantation were observed. The uncorrected visual acuity （UCVA）, best spectacle-corrected visual acuity （BSCVA）, and intraocular pressure （IOP） changes of patients before and after surgeries were compared. The corneal edema, anterior chamber flash, IOL position, and iris were observed by the slitlamp microscope. The number of corneal endothelium was counted. Results The average time of follow-up was two years. The UCVA of five eyes was 0.5 or better （38.5%） and the BSCVA of six eyes was 0.5 or better （46.2%）. The IOP did not change significantly before and after surgeries. There were no significant cornea edema, decentration or tilting of IOL, and inflammation of anterior chamber. The mean loss rate of endothelial cells was 10.1%. There were two eyes with the iris injury and two eyes with the iris hemorrhage during the surgery, but were absorbed shortly after the surgery. There was one eye with IOL dislocation during the follow-up and the IOL was refixed. No macular edema was observed. Conclusion Artisan irisfixated IOL implantation is a safe and effective method for treating aphakic eyes. The surgery is simple with less damage to tissues and less complications. The postoperative visual acuity can be significantly improved.
