玻璃体切割术中保留前囊膜的临床疗效观察

目的: 评价玻璃体手术中保留前囊膜的临床效果。方法: 选取 2004- 02/2005- 02 在我院行保留前囊膜的玻璃体晶状体联合切割手术患者 15 例, 其中巨大裂孔源性视网膜脱离患者 4 例, 糖尿病性视网膜病变(Ⅵ期)患者 2 例, 裂孔源性视网膜脱离患者 9 例(复发性裂孔原性视网膜脱离患者 3 例)PVR分级均在 C级以上。眼内注气者 6 例, 硅油填充者 9 例。追踪观察至少3mo, 根据其手术前后的视力及并发症对手术效果做出评价。结果: 所有患者术后视力都高于术前或与术前相等, 平均视力提高 3±3 行。有 8 例患者在术后 2mo 成功植入后房型人工晶状体( PCIOL) , 其中 2 例为硅油取出的同时植入, 另外 6 例为眼内注气患者。术后随访期间未发现角膜失代偿、瞳孔阻滞和视网膜再次脱离等并发症。结论: 完整保留前囊膜可以避免复杂性视网膜脱离患者在玻璃体联合晶状体切割术中和术后由于眼内注气或硅油填充而产生的并发症, 并有利于 PCIOL的植入,保留了虹膜的正常形态, 是一种理想的手术方式。

Preservation of anterior capsule during vitrectomy and lensectomy

AIM: To evaluate the preservation of anterior capsule during vitrectomy and lensectomy.ment (RD) and grade C proliferative vitreoretinopathy (PVR)underwent pars plana vitrectomy (PPV) and pars plana lensectomy (PPL) with preservation and polishing of the anterior capsule. Of the 15 eyes, 4 eyes had giant tear, 3 had recurrent rhegmatogenous retinal detachment (RRD), 2 had diabetic retinopathy. Totally 6 eyes had gas and 9 had silicone oil tamponade. The surgeries were evaluated according to the visual acuity (VA) and the postoperative complications during the follow-up of at least 3 months.in all eyes, improved by 3± 3 lines overall. Eight eyes were implanted posterior chamber intraocular lens (PCIOL) successfully at 2-3 months after operation, including 6 having gas and 2 having silicone oil tamponade. No eyes had central anterior capsule opacity, corneal decompensation, puplillary block, retina redetachment or other complications.an intact anterior capsule in eyes with RD and PVR. Preserving the anterior capsule can help preventing intraoperative and postoperative complications of gas or silicone oil, simplify future PCIOL placement, and maintaining a normal iris appearance.
