To demonstrate the outcomes of pars plana vitrectomy in patients with custom flexible iris prosthesis (CFIP).
The medical records of patients who underwent CFIP placement were retrospectively reviewed. Patients who underwent pars plana vitrectomy concurrent with or after placement of CFIP were identified. Preoperative, intraoperative, and postoperative parameters were analyzed. Surgeons were surveyed regarding the technical aspects of the vitreoretinal surgery. Outcome measures included: anatomic success, complications, surgeon-rated ease of visualization through CFIP during pars plana vitrectomy, and Snellen best-corrected visual acuity.
Twenty-four surgeries were performed in 20 eyes of 20 patients. Postoperative best-corrected visual acuity improved in 11 eyes (55%), remained unchanged in 5 eyes (25%), and declined in 4 eyes (20%) after a mean follow-up of 16.1 ± 16.\nths (range: 3-53 months). No intraoperative complications were noted. Short-term anatomical success was 100%. Postoperative complications occurred in five eyes (recurrent retinal detachment in three eyes, recurrent epiretinal membrane in 1 eye, and CFIP and intraocular lens subluxation in 1 eye).
Visualization for pars plana vitrectomy with the assistance of both direct and wide angle viewing systems through the 3.35 mm pseudopupil of a CFIP is viable in the surgical management of complex vitreoretinal diseases.
展示定制柔性虹膜假体（CFIP）患者行玻璃体切除术的结果。
回顾性分析接受CFIP植入患者的病历。确定在CFIP植入同时或之后行玻璃体切除术的患者。分析术前、术中和术后参数。就玻璃体视网膜手术的技术方面对手术医生进行调查。结果指标包括：解剖学成功、并发症、手术医生对玻璃体切除术期间通过CFIP可视化难易程度的评分以及Snellen最佳矫正视力。
20例患者的20只眼进行了24次手术。平均随访16.1±16个月（范围：3 - 53个月）后，11只眼（55%）的术后最佳矫正视力提高，5只眼（25%）保持不变，4只眼（20%）下降。术中未发现并发症。短期解剖学成功率为100%。5只眼出现术后并发症（3只眼复发性视网膜脱离，1只眼复发性视网膜前膜，1只眼CFIP和人工晶状体半脱位）。
在复杂玻璃体视网膜疾病的手术治疗中，借助直接和广角观察系统通过CFIP的3.35毫米假瞳孔进行玻璃体切除术的可视化是可行的。
