Health‐related quality of life after cataract surgery with the phacoemulsification technique and intraocular lens implantation

PURPOSE: Disease-specific instruments have shown significant gains in measuring health-related quality of life (HRQoL) in subjects having cataract surgery. However, the usage of generic instruments has resulted in conflicting evidence. METHODS: In this prospective study, we have evaluated the impact of cataract surgery on subjects' HRQoL measured with a 15-dimension generic instrument, the 15D. The HRQoL of cataract subjects was compared with that of an age- and gender-standardized sample of the general population in Finland. A total of 152 subjects (mean age 74 years, 66% females) with a first-eye cataract surgery completed the 15D questionnaire both before and 12 months after cataract surgery. RESULTS: When compared with the general population, cataract subjects had much lower HRQoL at baseline (mean difference 0.037 (95% CI: 0.020, 0.054), p < 0.001). At 12 months after cataract surgery, the overall utility index improved from the mean of 0.837 to 0.855 (mean difference 0.018 (95% CI: 0.007, 0.029), p = 0.002). Significant improvement was observed on the following five dimensions: seeing, moving, hearing, usual activities and discomfort/symptoms in the 15D questionnaire. CONCLUSION: Our data indicate that at 12 months after first-eye cataract surgery, patients' HRQoL is slightly better than that before surgery. However, patients' postoperative HRQoL may remain lower than that of an age-and gender-standardized control population.
