To investigate the functional outcome, as defined using the Catquest questionnaire, for patients with posterior capsule opacification (PCO) and low corrected distance visual acuity (CDVA), after capsulotomy.
Thirty-one patients with PCO and visual acuity ≥ 0.6 (log MAR, ≤ 0.25 decimal notation) in the PCO eye were examined before and 1 month after capsulotomy. An ophthalmic examination, procuring of a digital image of the posterior lens capsule and completion of Catquest were carried out.
Mean CDVA (p < 0.001), disabilities in daily life (p = 0.004), activity (p = 0.012), symptoms of glare (p = 0.003) and satisfaction with vision (p < 0.001) all improved after capsulotomy. Sixty-five per cent of patients had good or very good benefit and 23% questionable or no benefit. The group with moderate benefit was only 6%. Compared with patients with PCO and better visual acuity, the number of patients with good benefit was greater than the number with moderate benefit.
Most patients with PCO and low CDVA reported improved visual function in daily life as defined using Catquest, after capsulotomy. The group with moderate benefit was small, indicating that the improvement was either substantial or negligible.
调查后囊混浊（PCO）和低矫正远视力（CDVA）患者在囊切开术后的功能结果，使用 Catquest 问卷进行定义。
对 31 例 PCO 视力≥0.6（logMAR，≤0.25 十进制标记）的患者在囊切开术前和术后 1 个月进行检查。进行眼科检查、获取后晶状体囊的数字图像和完成 Catquest。
平均 CDVA（p<0.001）、日常生活障碍（p=0.004）、活动能力（p=0.012）、眩光症状（p=0.003）和对视觉的满意度（p<0.001）在囊切开术后均得到改善。65%的患者有良好或非常好的获益，23%的患者有可疑或无获益。只有 6%的患者获益程度为中等。与 PCO 和较好视力的患者相比，有良好获益的患者数量多于获益程度为中等的患者。
大多数 PCO 和低 CDVA 的患者在囊切开术后报告了 Catquest 定义的日常生活中视觉功能的改善。获益程度为中等的患者数量较少，表明改善程度要么较大，要么可以忽略不计。
