BACKGROUND:Several studies described the benefits of the heparin-surface-modified intraocular tens (HSM IOL) with regard to the reduced inflammation in routine extracapsular cataract extractions. However, limited information is available about the advantages of the HSM IOL in patients with an intraocular inflammation. AIM:To assess the eventual benefits of the HSM IOL compared to the regular polymethylmethacrylate intraocular lens (PMMA IOL) in patients with uveitis. METHODS:A retrospective study of 43 patients with uveitis of various origins who underwent an extracapsular cataract extraction (24 with HSM, 19 with PMMA IOL). The activity of intraocular inflammation, visual acuity, eventual complications, and medications were examined. Standardized follow-up dates were used (before surgery, one and fourteen days, five and eleven months after surgery.) RESULTS:No difference in the inflammatory, activity was noted between HSM and PMMA groups; neither at short term clinical evaluation, nor at five months after surgery. Despite a slightly better visual acuity in the HSM group before surgery, no long term differences were observed. After surgery the increase in visual acuity was similar for both groups, as well as the frequency of cystoid macular oedema (CMO) and synechiae. Fewer patients in HSM group required Nd:YAG posterior capsulotomy, but the difference was not significant. CONCLUSION:No clinical advantage was found when the HSM IOL was compared with the regular PMMA IOL in 43 patients with uveitis.

背景:多项研究描述了肝素表面修饰眼内张力(HSM IOL)在常规囊外白内障摘除术中减少炎症方面的益处。但是,关于眼内炎症患者中HSM IOL的优势的信息很少。
目的:评估与常规聚甲基丙烯酸甲酯人工晶状体(PMMA IOL)相比,HSM IOL在葡萄膜炎患者中的最终益处。
方法:回顾性研究43例不同来源葡萄膜炎患者的囊外白内障摘除术(HSM 24例,PMMA IOL 19例)。检查眼内炎症,视力,最终并发症和药物的活动。使用标准化的随访日期(手术前,手术后的第1天,第14天,手术后的第5个月和第11个月)。
结果:HSM和PMMA组之间在炎症,活性方面没有差异;既不进行短期临床评估,也不在术后五个月进行评估。尽管术前HSM组的视敏度稍好,但未观察到长期差异。手术后,两组的视敏度增加,囊状黄斑水肿(CMO)和粘连的发生率相似。 HSM组需要Nd:YAG后囊切开术的患者较少,但差异无统计学意义。
结论:将HSM IOL与常规PMMA IOL相比较在43例葡萄膜炎患者中未发现临床优势。
