25 G玻璃体切割系统在玻璃体切除术后白内障的应用

观察25G玻璃体切割系统在玻璃体切除术后白内障手术中的应用，探讨其在玻璃体切除术后白内障的手术中的应用效果。方法将29例（29只眼）玻璃体切除术后的白内障患者，随机分成3组：A组在25G套管辅助下行白内障摘除人工晶状体植入术，B组在20G灌注下行白内障摘除人工晶状体植入术，C组直接行白内障摘除人工晶状体植入术。比较3组之间的差异。结果A组手术时间短，术中低眼压容易控制，手术安全性较高。B组手术时间较长，术中低眼压容易控制，手术安全性较高。C组手术时间短，但是术中低眼压不容易控制，同时容易出现后囊膜破裂等并发症。结论在玻璃体切除术后白内障手术中，应用25G套管建立灌注，缩短了手术时间，同时提高的手术的安全性。

Application of 25G vitrectomy system in cataract surgeries after vitrectomy

Objective To explore the application and outcomes of 25G vitrectomy system to treat cataract after vit-rectomy.Methods We collected clinical data of 39 patients （39 eyes） who previously received vitrectomy for other rea-sons and presented with cataract after the vitrectomy .Patients were divided into 3 groups randomly .In group A, patients received cataract extraction and intraocular lens implantation using a 25G vitrectomy system to aid intraocular irrigation .In group B, a 20G vitrectomy system was used to aid intraocular irrigation .In group C, patients underwent cataract extraction and intraocular lens implantation without aid of vitrectomy systems .Results It was easier to maintain intraoperative IOP within normal range for patients in group A .Required operation time was also the shortest .There were no complications re-ported.The operation time required was relatively longer for patients in group B , but IOP was also easier to control .In group C, patients needed less operation time than patients in group B , but intraoperative IOP was hard to control .Conclu-sion The use of 25G vitrectomy system helps to control intraoperative IOP , shorten the operation time , and reduce possi-ble complications in cataract surgeries for patients who previously received vitrectomy .
