The aim of the study was to calculate the corneal endothelial permeability (Pac) before, one week, and one month after planned extracapsular cataract extraction and intraocular posterior chamber lens implantation in two groups with axial myopes (8 eyes) and normal eyes (6 eyes): in patients aged 60-75 years. Patients with minimal endothelial disorders have been found to have abnormal endothelial permeabilities. Each operated eye was submitted to fluorophotometry of the anterior segment with measurement of corneal endothelial permeability (Fluorotron Master, Coherent), the day before surgery, 1 week and 1 month afterwards. The measuring of cornea thickness measurement and endothelial cell counting was done by specular microscopy with pachymeter. Corneal permeability clearly increased 1 week after surgery in both groups; 1 months after surgery Pac was normalized in both groups, except for all pseudophakic myopic eyes (axial length: 25-27 mm) with longer surgical procedures (> 20 min), those associated with a greater increase in corneal endothelial permeability. No changes in corneal thickness and endothelial cell density were noted as a result of surgery. Myopic eye with longer surgical procedures was found as a risk factor for an increase in corneal endothelial permeability.
本研究的目的是计算两组患者（8只眼的轴性近视患者和6只眼的正常眼患者）在计划行白内障囊外摘除术及人工晶状体后房型植入术前、术后1周和1个月时的角膜内皮通透性（Pac）：患者年龄在60 - 75岁。已发现内皮疾病轻微的患者存在异常的内皮通透性。在手术前一天、术后1周和1个月，对每只手术眼进行眼前节荧光光度测定以测量角膜内皮通透性（Fluorotron Master，相干公司）。角膜厚度测量和内皮细胞计数通过带有测厚仪的镜面显微镜进行。两组患者术后1周角膜通透性均明显增加；术后1个月，除所有手术时间较长（> 20分钟）的人工晶状体植入近视眼（眼轴长度：25 - 27 mm）外，两组的Pac均恢复正常，这些眼与角膜内皮通透性的更大增加有关。手术未导致角膜厚度和内皮细胞密度发生变化。发现手术时间较长的近视眼是角膜内皮通透性增加的一个危险因素。
