To evaluate the effects of air bubbles on clear corneal incision (CCI) in patients who had phacoemulsification surgery, and to compare this type of CCI architecture with patients who had no air bubbles after phacoemulsification surgery, using anterior segment optical coherence tomography (AS-OCT).
Eyes which had undergone uneventful phacoemulsification cataract surgery with implantation of a posterior chamber intraocular lens (IOL) were equally randomized into two groups. Group 1 comprised patients with anterior chamber air bubble injection after phacoemulsification, and Group 2 comprised patients who had undergone phacoemulsification surgery without anterior chamber air bubble. Postoperative evaluation included AS-OCT (Heidelberg Engineering, Germany) and pneumatic tonometry (Nidek NT-1000 Pneumatic Tonometer, Japan) in the 2nd hour, then at 1 week, and 1 month. Astigmatic changes assessed with corneal topography after phacoemulsification cataract surgeries were noted.
Evaluation was made of 40 eyes of 28 patients (10 female, 18 male) as 20 eyes in Group 1 and 20 eyes in Group 2. On the first postoperative day, the endothelial gap rate was 13.3% in Group 1 and 57.1% in Group 2 ( = 0.02), and this continued until the 1-month follow-up examination. The Descemet's membrane detachment (DMD) rate was 0% in Group 1 and 42.8% in Group 2 on postoperative day 1 ( = 0.006), and this continued at the 1-month follow-up examination. At 1 month postoperatively, the rates of optical coherence tomography (OCT) parameters were similar. There were no significant differences between preoperative astigmatism and postoperative astigmatism in the group analyses.
In this study, air bubbles decreased the rate of DMD and of endothelial and epithelial gap during the early postoperative period.
使用眼前节光学相干断层扫描（AS-OCT）评估气泡对接受超声乳化手术患者透明角膜切口（CCI）的影响，并将这种类型的CCI结构与超声乳化手术后无气泡的患者进行比较。
接受了顺利的超声乳化白内障手术并植入后房型人工晶状体（IOL）的眼睛被随机分为两组。第1组包括超声乳化后前房注入气泡的患者，第2组包括未进行前房气泡注入的超声乳化手术患者。术后评估包括在术后第2小时、1周和1个月时进行AS-OCT（德国海德堡工程公司）和气动眼压测量（日本尼德克NT-1000气动眼压计）。记录超声乳化白内障手术后用角膜地形图评估的散光变化。
对28例患者（10例女性，18例男性）的40只眼睛进行了评估，第1组20只眼睛，第2组20只眼睛。术后第1天，第1组的内皮间隙率为13.3%，第2组为57.1%（P = 0.02），这种情况一直持续到1个月的随访检查。术后第1天，第1组的Descemet膜脱离（DMD）率为0%，第2组为42.8%（P = 0.006），在1个月的随访检查中这种情况仍持续存在。术后1个月，光学相干断层扫描（OCT）参数率相似。在组分析中，术前散光和术后散光之间没有显著差异。
在本研究中，气泡在术后早期降低了DMD以及内皮和上皮间隙的发生率。
