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.

Box plot showing the seasonal distribution of pre-operative Pittsburgh Sleep Quality Index (PSQI) of patients undergoing cataract surgery for implantation of a clear or yellow intra-ocular lens (IOL). The horizontal line in each diagram indicates the median score on the PSQI. The height, positive error bar, and negative error bar of each box indicate the 25th–75th percentiles, maximum value, and minimum value, respectively. Patients who had surgery in summer exhibited relatively better sleep quality than those undergoing surgery in winter, although the differences did not reach statistical significance.

Mentions: There were no significant differences in the QOL of patients undergoing bilateral versus unilateral surgery (Table 4). Patients who had surgery in summer exhibited relatively better sleep quality than those who had surgery in the winter although the differences did not reach statistical significance (Fig. 4, Table 5).
