Phacoemulsification is routinely performed with the patient lying supine on the surgical table with his or her head flat and facing the overhead microscope. This routine technique can be a challenge in medical conditions such as kyphosis, scoliosis, orthopnea, Meniere's disease, and CNS abnormality. Some cardiovascular and respiratory conditions make the patients breathless when they lie down, whereas other neurological and spinal problem patients are also equally uncomfortable. The only reasonable solution to conduct surgery on a patient who cannot lie down flat on the operating table is to position them face to face in a sitting position. We describe an innovative phacoemulsification technique in a sitting position called "phacosit" in an 80-year-old wheelchair-bound female patient who was denied cataract surgery by other eye surgeons owing to her medical condition.
白内障乳化术通常在手术台上让患者仰卧，头部放平，面对头顶的显微镜进行。但对于一些患有脊柱后凸、脊柱侧凸、端坐呼吸、梅尼埃病、中枢神经系统异常的患者，这种常规技术可能会带来挑战。一些心血管和呼吸系统疾病会使患者在躺下时呼吸困难，而其他神经和脊柱问题患者也同样感到不适。对于那些不能平躺在手术台上的患者，唯一合理的解决方法是让他们面对面地坐在座位上进行手术。我们描述了一种针对无法平卧的患者的创新的坐位白内障乳化术技术，称其为“phacosit”，该技术适用于一位 80 岁的坐轮椅女性患者，她因身体状况不佳而被其他眼科医生拒绝进行白内障手术。
