To compare the changes in the anterior chamber depth (ACD) and in the refractive outcomes after combined phacovitrectomy with respect to the endotamponade (balanced salt solution, air, sulfur hexafluoride [SF 6 , gas]).
Department of Ophthalmology, University Hospital Ulm, Ulm, Germany.
Retrospective, longitudinal case-control study.
160 eyes of 160 patients were included in the study. 120 eyes underwent phacoemulsification with in-the-bag implantation combined with vitrectomy and were divided into 3 groups according to tamponade (balanced salt solution, air, gas). 40 control eyes with cataract surgery only were included. Further inclusion criteria were uneventful surgery, no postoperative complications and absence of corneal pathology. Endpoints were ACD as measured by swept-source optical coherence tomography-based biometry (IOLMaster 700) preoperatively, 1 to 2 days and 6 weeks postoperatively and refractive prediction error (PE) using the Barrett and Haigis formulas.
Within the first 2 days after surgery the ACD was shallower in the eyes left with gas or air tamponade, when compared with balanced salt solution or cataract surgery alone ( P < .001). This effect diminished 6 weeks later, and all eyes reached comparable ACD ( P = .396). The refractive PE was slightly, but statistically significantly higher in the gas group when compared with cataract surgery alone ( P = .012 for Barrett, P = .006 for Haigis).
The resulting ACD after combined phacovitrectomy was independent of the tamponade used, but a gas-tamponade was associated with a higher refractive PE.
比较联合晶状体玻璃体切除术在使用不同眼内填充剂（平衡盐溶液、空气、六氟化硫[SF6，气体]）时前房深度（ACD）和屈光结果的变化。
德国乌尔姆大学医院眼科。
回顾性纵向病例对照研究。
160例患者的160只眼纳入研究。120只眼接受了囊袋内植入式超声乳化联合玻璃体切除术，并根据填充剂分为3组（平衡盐溶液、空气、气体）。纳入40只仅行白内障手术的对照眼。进一步的纳入标准为手术顺利、无术后并发症且无角膜病变。观察指标为术前、术后1至2天和术后6周通过基于扫频源光学相干断层扫描的生物测量法（IOLMaster 700）测量的ACD，以及使用巴雷特公式和海吉斯公式计算的屈光预测误差（PE）。
术后第1至2天，与使用平衡盐溶液或仅行白内障手术的眼相比，使用气体或空气填充的眼ACD较浅（P <.001）。6周后这种效应减弱，所有眼的ACD达到相似水平（P =.396）。与仅行白内障手术相比，气体组的屈光PE略高，但具有统计学意义（巴雷特公式P =.012，海吉斯公式P =.006）。
联合晶状体玻璃体切除术后的ACD与所使用的填充剂无关，但气体填充与较高的屈光PE相关。
