The aim of this study was to examine whether differences exist after cataract surgery is performed in patients over and under 90 years of age.
Retrospective, nonrandomized study.
Cataract surgery was performed in 21 patients (31 eyes) who were older than 90 years of age and in 45 patients (70 eyes) who were younger than 90 years of age.
The medical records of all patients who underwent cataract surgery between January 2005 and September 2010 at Dokkyo Medical University Koshigaya Hospital were reviewed. Factors evaluated included systemic disease, changes in systemic condition, surgical time, preoperative and postoperative visual acuity, corneal endothelial cell density, and intraoperative complications.
The group of patients older than 90 years of age experienced greater occurrences of systemic disease (p < 0.05; χ(2) test) and intraoperative changes in systemic conditions (p < 0.001; χ(2) test). These patients also had significantly lower preoperative visual acuity (p < 0.001; Student t test). No differences were noted between the 2 age groups in surgical time, postoperative visual acuity, preoperative corneal endothelial cell density, or intraoperative complications.
Poorer cataract surgery outcome results were noted in patients older than 90 years due to systemic disease and intraoperative changes in systemic condition. Factors that need to be taken into consideration prior to performing cataract surgery in older patients include age, systemic disease, and the likelihood of intraoperative changes in systemic condition.
本研究旨在探讨 90 岁以上和 90 岁以下患者白内障手术后是否存在差异。
回顾性、非随机研究。
对 2005 年 1 月至 2010 年 9 月期间在独协医科大学久留米医院接受白内障手术的 21 名（31 只眼）90 岁以上患者和 45 名（70 只眼）90 岁以下患者的病历进行了回顾。
评估的因素包括全身疾病、全身状况变化、手术时间、术前和术后视力、角膜内皮细胞密度和术中并发症。
90 岁以上患者全身疾病发生率较高（p < 0.05；卡方检验），术中全身状况变化发生率较高（p < 0.001；卡方检验）。这些患者的术前视力也显著较低（p < 0.001；学生 t 检验）。两组患者的手术时间、术后视力、术前角膜内皮细胞密度或术中并发症均无差异。
90 岁以上患者由于全身疾病和术中全身状况变化，白内障手术结果较差。在为老年患者进行白内障手术之前，需要考虑的因素包括年龄、全身疾病以及术中全身状况变化的可能性。
