Supplementary Material for: Three-Year Follow-Up of Results of Intraocular Lens Fixation in Patients with Retinitis Pigmentosa

This is a retrospective, consecutive, noncomparative case series of 6 eyes of 5 RP patients who had undergone PPV and IOL implantation. The aim of this case series was to report the long-term outcomes of pars plana vitrectomy (PPV) with intraocular lens (IOL) implantation in patients with retinitis pigmentosa (RP). The surgical procedures, visual function, refractive error, corneal endothelial cell density, intraocular pressure, and retinal morphology were evaluated before and three years after the surgery. Six eyes of 5 RP patients that had undergone PPV and IOL implantation with or without suturing for lens dislocation were studied. The visual acuity was maintained or improved at 3 years after surgery in all 6 eyes. No intraoperative complications occurred in any of the cases. The mean deviation of the Humphrey Field Analyzer 10-2 program and the retinal morphology evaluated by optical coherence tomography did not show any abnormal changes before and after surgery. In two eyes, the postoperative refractive error was more myopic than the attempted refractive error. In conclusion, PPV with IOL implantation can be performed safely in RP patients, and the long-term visual acuity can be maintained.本研究为回顾性、连续性、非对照病例系列研究，纳入5名视网膜色素变性（retinitis pigmentosa, RP）患者共6只眼，所有受试者均接受了经睫状体平坦部玻璃体切割术（pars plana vitrectomy, PPV）联合人工晶状体（intraocular lens, IOL）植入术。本病例系列的研究目的为报告视网膜色素变性患者接受经睫状体平坦部玻璃体切割术联合人工晶状体植入术后的长期预后情况。研究评估了手术前与术后3年时的手术操作细节、视功能、屈光不正状态、角膜内皮细胞密度、眼压及视网膜形态。本研究纳入的6只眼均来自5名视网膜色素变性患者，均接受了经睫状体平坦部玻璃体切割术联合人工晶状体植入术，其中部分患者联合了晶状体脱位缝合固定术。术后3年时，所有6只眼的视力均维持或有所提升。所有病例均未出现术中并发症。汉弗莱视野分析仪10-2程序的平均偏差值，以及经光学相干断层扫描评估的视网膜形态，在手术前后均未出现异常改变。2只眼的术后屈光不正较预设矫正屈光不正更偏向近视。综上，经睫状体平坦部玻璃体切割术联合人工晶状体植入术可安全应用于视网膜色素变性患者，且可维持长期视功能。
