Abstract

Purpose: To evaluate the quality of life (QoL) and vision-related QoL in patients suffering from coexisting glaucoma and cataract.

Study design: Cross-sectional analytical study.

Methods: This study included a total of 222 cases: 163 patients suffering from coexisting glaucoma and cataract as the patient group and 59 healthy individuals as the control group. Data were gathered via EuroQol five-dimensional (EQ-5D) and National Eye Institute-Visual Functioning Questionnaire 39 (NEI-VFQ 39). The results were then compared before and one month after cataract surgery in the patient and control groups.

Results: The mean and 95% confidence interval of overall vision-related QoL scores in healthy individuals and patients in the pre- and postoperative phases were 86.65 (69.3–104.0), 48.7 (9.4–88.1), and 56.1 (12.2–100.0), respectively. There were significant differences among the 3 groups regarding all NEI-VFQ 39 items (P < 0.05). The mean and confidence interval of EQ-5D scores in the pre- and postoperative phases were 0.42 (0.21–0.64) and 0.58 (0.39–0.78), respectively (P = 0.017); for healthy individuals it was 0.70 (0.59–0.80). After surgery, all QoL items significantly increased among patients (P < 0.05). There were also significant differences in the scores compared to healthy individuals (P < 0.05). One month after surgery, all vision-related QoL item scores obtained by NEI-VFQ 39 and all QoL items scores obtained by EQ-5D were significantly lower in the treated patients than in healthy individuals (P < 0.05).

Conclusions: In patients suffering from coexisting glaucoma and cataract, The overall QoL and vision-related QoL scores improved after cataract surgery. However, there was a significant difference between patients and healthy individuals, with the healthy group having a superior score than the patients, both pre- and postoperatively.
