To compare surgeon experience and the outcomes of phacoemulsification using 2 different illumination techniques for cataract extraction.
A prospective interventional case series was performed on 20 consecutive patients (20 eyes) with senile cataract who underwent phacoemulsification enhanced with a 23-G endoillumination probe. The main outcome measures were the surgeon's perception of depth of field and quality of visibility of intraocular structures, ease of performance of the surgical procedure, effectiveness, and complications related to the procedure. A surgeon-specific questionnaire was administered at the end of the procedure.
Surgery was successfully performed in all patients without any complications. The surgeon indicated that lateral endoillumination markedly enhanced the details of the lens structures, mainly the posterior capsule visualization, better than the coaxial lighting with the surgical microscope. Lateral endoillumination created an enhanced 3D effect and improved the depth perception of lens intraoperatively.
The lateral illumination technique with a 23-G endoilluminator probe placed in the anterior chamber through a paracentesis creates an enhanced 3D effect and improves depth perception of lens during phacoemulsification. These benefits increase the safety of the procedure.
比较使用两种不同照明技术进行白内障摘除术时外科医生的经验及超声乳化手术的效果。
对20例连续的老年性白内障患者（20只眼）进行前瞻性干预性病例系列研究，这些患者接受了使用23G眼内照明探头增强的超声乳化手术。主要观察指标包括外科医生对景深的感知、眼内结构的可见度质量、手术操作的难易程度、有效性以及与手术相关的并发症。在手术结束时发放针对外科医生的问卷。
所有患者均成功完成手术，无任何并发症。外科医生表示，与手术显微镜同轴照明相比，侧面眼内照明能显著增强晶状体结构的细节，主要是后囊膜的可视化。侧面眼内照明产生了增强的三维效果，并改善了术中晶状体的深度感知。
通过穿刺在前房放置23G眼内照明探头的侧面照明技术，在超声乳化手术过程中可产生增强的三维效果并改善晶状体的深度感知。这些益处提高了手术的安全性。
