The authors describe a simplified and safer technique for surgical removal of hereditary or idiopathic soft subluxated lenses. Five eyes of three patients underwent intercapsular aspiration of the lens material. A side-port cannula was introduced through the pars plicata while the eyes were pressurized by an anterior chamber maintainer. This was followed by anterior vitrectomy and capsulectomy. With this technique, the risk of vitreous loss, which can occur with an anterior approach, and the risk of the spread of lens particles into the vitreous, which can occur with a lensectomy with a vitrectomy probe, are avoided. Postoperatively, optical correction was achieved with a contact lens in the two children and with an anterior chamber intraocular lens in the adult. Final visual acuity was 6/9 or better in all eyes. No surgical or other complication occurred during 2 to 4 years of follow-up. A soft subluxated lens can be removed without the risks of vitreous loss or spread of lens particles into the vitreous, reducing the probability of severe complications.
作者描述了一种用于手术摘除遗传性或特发性软性半脱位晶状体的简化且更安全的技术。三名患者的五只眼睛接受了晶状体物质的囊内抽吸。在前房维持器对眼睛加压的同时,通过睫状体平坦部插入一个侧端口套管。随后进行前部玻璃体切除术和晶状体囊切除术。采用这种技术,可避免前部入路可能出现的玻璃体丢失风险,以及使用玻璃体切割探头进行晶状体切除时可能出现的晶状体颗粒扩散至玻璃体的风险。术后,两名儿童通过佩戴隐形眼镜实现了光学矫正,成人则通过植入前房型人工晶状体实现了光学矫正。所有眼睛的最终视力均为6/9或更好。在2至4年的随访期间未发生手术或其他并发症。软性半脱位晶状体可以被摘除,而不会有玻璃体丢失或晶状体颗粒扩散至玻璃体的风险,从而降低了严重并发症的发生概率。
