SIGNIFICANCE 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.

PURPOSE 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.

METHODS 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).

RESULTS 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).

CONCLUSIONS 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.
