Our study suggests that patients would benefit from adjusting their distance spectacles several years after cataract surgery. This may lead to a better quality of life for these patients.
The purpose of this study was to determine whether patients' distance vision is optimally corrected with spectacles 6 to 7 years after cataract surgery and whether patients with glaucoma who regularly visit an ophthalmologist have more correct power in their spectacles.
A total of 153 patients (153 eyes) who underwent cataract surgery with phacoemulsification at Oslo University Hospital were examined 6 to 7 years after surgery. Patients with better or equal best-corrected distance visual acuity in the study eye compared with the other eye were included (n = 90; 59%). Vision-related outcomes were measured and analyzed, including a modified version of the visual function questionnaire, Visual Function-14 (VF-14).
A significant difference was found in the logMAR score between the patients' habitual correction (if any) and those with best-corrected distance visual acuity measured at the postoperative study examination (0.20 ± 0.40 and 0.10 ± 0.39, respectively; P < .0001). Patients with glaucoma (n = 17) did not have more correct power of their spectacles than did patients without glaucoma (n = 73; P = .38). The overall mean VF-14 score was 89%, with a statistically significant correlation between a high VF-14 score and a good habitual distance correction (r = -0.82; P < .0001).
This study indicates that, although the patients are quite satisfied with their visual function 6 to 7 years after cataract surgery, many patients are not making the most of their visual potential. Thus, there seems to be a need for better monitoring of patients' distance refraction and spectacle use for an extended period after cataract surgery.
我们的研究表明，白内障手术后数年，患者调整其远用眼镜会受益。这可能会改善这些患者的生活质量。
本研究的目的是确定白内障手术后6至7年患者的远视力是否通过眼镜得到最佳矫正，以及定期就诊眼科医生的青光眼患者眼镜度数是否更合适。
对奥斯陆大学医院153例接受白内障超声乳化手术的患者（153只眼）在术后6至7年进行检查。纳入研究眼最佳矫正远视力优于或等于对侧眼的患者（n = 90；59%）。测量并分析与视力相关的结果，包括视觉功能问卷Visual Function-14（VF-14）的改良版。
患者的习惯矫正（如有）与术后研究检查时测量的最佳矫正远视力之间的logMAR评分存在显著差异（分别为0.20±0.40和0.10±0.39；P <.0001）。青光眼患者（n = 17）眼镜度数并不比非青光眼患者（n = 73）更合适（P =.38）。VF-14总体平均评分为89%，VF-14高分与良好的习惯远用矫正之间存在显著相关性（r = -0.82；P <.0001）。
本研究表明，尽管患者在白内障手术后6至7年对其视觉功能相当满意，但许多患者并未充分发挥其视觉潜能。因此，白内障手术后似乎需要对患者的远视力屈光度和眼镜使用情况进行更长时间的更好监测。
