Bottom Line: Changes in sub-scale scores of VFQ-25 and PSQI were compared.Sub-scale analyses for improvement after surgery revealed significant differences in ocular pain scores on the VFQ-25 (Y>C; the higher the score, the better the outcome).These effects were successfully represented by the change in scores rather than absolute post-operative scores because individual standard of response may often change after intervention, recognized as a response shift phenomenon in patient-reported outcome study.

ABSTRACT

Background: This study compared post-operative quality of life and sleep according to the type of cataract opacity and color of the implanted intra-ocular lens (IOL).

Methods: This is a cohort study and participants were 206 patients (average age 74.1 years) undergoing cataract surgery with the implantation of a clear ultra-violet (UV)-blocking IOL (C) or a yellow blue-light-blocking IOL (Y). Participants were evaluated using the National Eye Institute Visual Function Questionnaire (VFQ-25) and Pittsburgh Sleep Quality Index (PSQI) before surgery and 2 and 7 months after surgery. Changes in sub-scale scores of VFQ-25 and PSQI were compared.

Results: Sub-scale analyses for improvement after surgery revealed significant differences in ocular pain scores on the VFQ-25 (Y>C; the higher the score, the better the outcome). Furthermore, there were significant differences between the two IOLs in terms of the sleep latency score (C>Y) and sleep disturbances score (C>Y). A posterior sub-capsular cataract was significantly correlated with improvements in ocular pain and sleep latency scores. These effects were successfully represented by the change in scores rather than absolute post-operative scores because individual standard of response may often change after intervention, recognized as a response shift phenomenon in patient-reported outcome study. Regarding seasonal differences, patients who had surgery in summer exhibited relatively better sleep quality than those who had surgery in winter.

Conclusions: Analysis of sub-scales of health indices demonstrated characteristic prognoses for each IOL and cataract type. Cataract surgery may potentially contribute to systemic health in older adults.

Changes in sub-scale scores on the National Eye Institute Visual Function Questionnaire (VFQ-25) after cataract surgery. Significantly greater improvements were seen in ocular pain scores 2 and 7 months after implantation of a yellow (Y) intra-ocular lens (IOL) than a clear (C) IOL (p<0.01 and p<0.05, respectively; unpaired t-test). There were no significant differences between the two groups for any of the other sub-scales. Data show mean differences in different sub-scale scores, calculated by subtracting post-operative values from pre-operative values, in patients implanted with a yellow IOL (n=135) or a clear IOL (n=71).

Mentions: Analysis of sub-scales on the VFQ-25 revealed a significantly greater improvement in ocular pain scores 2 and 7 months after surgery in the case of patients implanted with a yellow IOL versus a clear IOL (p<0.01 and p<0.05, respectively; unpaired t-test; Fig. 1). The improvement in color vision was not significant in either group, and there were no significant differences between the two groups for any of the other sub-scales. There was >15 points improvement in scores for mental health, peripheral vision, distance vision, near vision, and general vision 7 months after surgery in both IOL groups (Fig. 1).
