一片式人工晶状体无缝线巩膜内固定术的临床观察

Novel technique of sutureless glueless intrascleral fixation of single-piece intraocular lens

目的:探讨一片式后房型人工晶状体(IOL)无缝线巩膜内固定术的单中心结果。方法:这项前瞻性研究共纳入50例无晶状体眼患者,均行一片式人工晶状体无缝线巩膜内固定术,术前和术后均行视力,裂隙灯和眼底检查,眼压测量,角膜测量,IOL MASTER测量,光学相干断层扫描(OCT)等眼科检查。结果:所有IOL均成功植入所需位置,术中无并发症。术后并发症包括角膜水肿(n=2),眼压升高(n=3),黄斑囊样水肿(n=1)以及偏离中心(n=2)。所有患者视力都得到了很好的恢复。对术后并发症病例的手术录像进行回顾性评估。角膜散光无明显变化。结论:经过6mo随访和各种参数的评估,采用一片式IOL进行无缝线、无胶巩膜固定术取得了良好的视力恢复效果。

AIM:To explore single centre results of sutureless intrascleral fixation of single-piece posterior chamber intraocular lens(IOL).METHODS:In this prospective study,50 aphakia cases were evaluated.Preoperative and postoperative visual acuity,slit lamp and fundus examination,applanation tonometry,keratometry,IOL MASTER measurement,optical coherence tomography(OCT),Scheimpflug imaging were done for an extensive evaluation.RESULTS:All IOLs were successfully implanted at the desired position without intraoperative complications.Postoperative complications included corneal edema(n=2),raised intraocular pressure(IOP)(n=3),cystoid macular edema(CME)(n=1)and decentration(n=2).All were managed to the level of good visual recovery.Surgery videos were retrospectively evaluated in cases of postoperative complications.There was no significant change in corneal astigmatism.CONCLUSION:After extensive 6mo follow up with evaluation of a variety of parameters,our technique of sutureless,glueless scleral fixation of IOL using single-piece IOL has shown favorable results and a potential option in visual rehabilitation.
