We retrospectively reviewed the records of 13 patients with pseudophakic bullous keratopathy who had undergone penetrating keratoplasty combined with suturing of a posterior chamber intraocular lens (PC-IOL) with angulated haptics to the posterior iris using the four optic positioning holes. Corneal endothelial decompensation was associated with anterior chamber IOLs in nine cases, with iris-fixated lenses in three cases, and a subluxated PC-IOL in one case. Visual acuity was 20/40 or better in 46%, 20/50 to 20/100 in 31%, and 20/200 or worse in 23%. These visual results are comparable with those reported for other similar surgical series. In four of seven eyes that had preoperative peripheral anterior synechiae (PAS), postoperative extension of at least 2 clock hours occurred; progressive angle-closure glaucoma developed in two of the four. In all four eyes, the extension occurred in the region directly overlying the lens haptics. The angulated haptics of iris-sutured PC-IOLs may predispose to extension of PAS and development of progressive angle-closure glaucoma.
我们回顾性分析了13例人工晶状体植入术后大泡性角膜病变患者的病历,这些患者接受了穿透性角膜移植术,并使用四个光学定位孔将有角度袢的后房型人工晶状体(PC-IOL)缝合至虹膜后部。角膜内皮失代偿在9例中与前房型人工晶状体有关,3例与虹膜固定型人工晶状体有关,1例与半脱位的PC-IOL有关。视力在46%的患者中为20/40或更好,31%的患者为20/50至20/100,23%的患者为20/200或更差。这些视力结果与其他类似手术系列报道的结果相当。在术前有周边前粘连(PAS)的7只眼中,有4只术后出现至少2个钟点范围的粘连扩展;其中2只发生了进行性闭角型青光眼。在所有4只眼中,粘连扩展均发生在人工晶状体袢直接覆盖的区域。虹膜缝合PC-IOL的角度袢可能易导致PAS扩展和进行性闭角型青光眼的发生。
