客观。-之前没有研究记录与白内障手术相关的第一眼、第二眼和双眼视力和主观视功能的改善。视觉功能和生活质量的主观方面的测量提供了无法通过简单的Snellen视力测量获得的信息。从三个城市的76个眼科诊所中，接受白内障摘除联合人工透镜植入术的患者（n=613）和对照患者（n=408）入组了一项前瞻性研究。术前、术后均行视力检查，视力从眼科记录中获得。在患有白内障且无其他眼部疾病的患者中，第二只眼手术前的基线主观视功能优于第一只眼手术前。术后第一眼和第二眼的主观视功能改善大致相等。术后双眼主观功能的改善明显大于第一眼或第二眼单独手术后的改善。手术组间视力改善的患者比例无统计学显著差异。双眼接受手术的患者报告主观视功能的改善比单眼接受手术的患者更大。因此，在这一人群中恢复双眼视觉似乎是有益的。这些发现支持了政策建议，即双眼白内障手术仍然是双侧白内障所致视力障碍患者的适当治疗方法。
Objective.-No previous study documents improvement in visual acuity and subjective visual function associated with cataract surgery in the first eye, second eye, and both eyes. Measurement of subjective aspects of visual function and quality of life provides information that cannot be obtained with simple measurement of Snellen visual acuity.Methods.-From 76 ophthalmology practices in three cities, patients undergoing cataract extraction with intraocular lens implantation (n=613) and comparison patients (n=408) were enrolled in a prospective study. Questionnaires elicited visual function information before and after surgery, and visual acuity was obtained from the ophthalmologic record.Results.-Among patients with cataract and no other eye disease, baseline subjective visual function before surgery in the second eye was better than that before surgery in the first eye. Improvement in subjective visual function was approximately equal postoperatively in first and second eyes. Improvement in subjective function in both eyes postoperatively was significantly greater than that after surgery in the first eye or second eye alone. No statistically significant difference across surgical groups in the proportion of patients demonstrating improvement in visual acuity was observed.Conclusion.-Patients who underwent surgery in both eyes reported greater improvement in subjective visual function than did those who underwent surgery in one eye. Thus, there seems to be a benefit associated with restoring binocular vision in this population. These findings support the policy recommendation that cataract surgery in both eyes remains the appropriate treatment for patients with bilateral, cataract-induced visual impairment.
