Abstract

We evaluated 200 consecutive IOGEL 1103 capsular bag intraocular lenses. We performed a 5 to 6 mm capsulorhexis and inserted the intraocular lens (IOL) through a 3.5 to 4.0 mm scleral tunnel with a Faulkner folder. Twenty-two cases were combined with trabeculectomy and ten with keratoplasty using a temporary keratoprosthesis. Mean follow-up was six months. The implant centered well and resisted capsular shrinkage. Iris touch to the optic was rare and did not provoke persistent pigment dispersion. In one third of the cases a cleft was discernible between the posterior convex IOL surface and the extended capsule despite thorough aspiration of viscoelastic and debris from the retrolental space. In 8% of cases, white flakes of unknown origin were observed at the IOL-capsule interface. In cases associated with pre-existing iritis or intraoperative iris trauma (iris manipulation, iridectomy, or synechiolysis in glaucoma patients), fibrin exudation as well as iridocapsular synechial formation and macrophage precipitation often ensued. Cellular precipitates, as evaluated by biomicroscopy and specular microscopy, were less pronounced and more transient than on poly(methyl methacrylate) IOLs. Best case visual acuity results were comparable to those with conventional implants; all eyes attained 20/40 or better and 97% achieved 20/25 or better. The 1103 was easier to implant through a capsulorhexis opening and suited the dimensions of the capsular bag better than the PC-12 model.

摘要

我们评估了连续200枚IOGEL 1103囊袋内人工晶状体。我们进行了5至6毫米的连续环形撕囊,并使用福克纳夹通过3.5至4.0毫米的巩膜隧道插入人工晶状体(IOL)。22例患者联合小梁切除术,10例患者使用临时角膜假体进行角膜移植术。平均随访时间为6个月。人工晶状体居中良好,能抵抗囊膜收缩。虹膜与人工晶状体光学部接触很少见,且未引发持续性色素播散。尽管已彻底抽吸晶状体后间隙的粘弹剂和碎屑,但在三分之一的病例中,仍可在人工晶状体后凸表面与伸展的囊膜之间看到裂隙。在8%的病例中,在人工晶状体 - 囊膜界面观察到不明来源的白色薄片。在既往有虹膜炎或术中虹膜创伤(青光眼患者的虹膜操作、虹膜切除术或虹膜粘连松解术)的病例中,常随之出现纤维蛋白渗出、虹膜 - 囊膜粘连形成和巨噬细胞沉淀。通过生物显微镜和镜面显微镜评估,细胞沉淀比聚甲基丙烯酸甲酯人工晶状体上的更不明显且更短暂。最佳视力结果与传统植入物相当;所有眼睛视力均达到20/40或更好,97%的眼睛达到20/25或更好。1103型人工晶状体通过连续环形撕囊开口植入更容易,且比PC - 12型号更适合囊袋尺寸。
