Vision-related Quality of Life Outcomes of Cataract Surgery in Advanced Glaucoma Patients

Abstract

Purpose: To demonstrate longitudinal postoperative vision-related quality of life and visual acuity changes after cataract surgery in advanced glaucoma patients.

Materials and methods: In total, 93 patients who underwent cataract surgeries were collected from June 2010 through June 2013 in Shanghai First People's Hospital, Shanghai Jiao Tong University, and were followed up for at least 3 months. Patients with advanced glaucoma, here defined as near total cupping of the optic nerve with severe visual field loss within 10 degrees of fixation, were enrolled. A standard phacoemulsification technique with the insertion of an intraocular lens was used. No complications occurred intraoperatively or postoperatively. Preoperative and 3-month postoperative vision-related quality of life were assessed in face-to-face interviews. The Chinese-version of the Low Vision Quality of Life Questionnaire (CLVQOL) was used. Wilcoxon signed-rank test was used to compare the differences in the best-corrected visual acuity (BCVA), weighted average LogMAR (WMAR), and CLVQOL scores. A binary logistic regression analysis was conducted to explore the potential factors associated with the change in CLVQOL scores.

Results: The overall changes in the CLVQOL composite scores ranged between 4 and 42 (median=19). Statistically significant increases occurred in the composite scores of all of the subscales, the total CLVQOL, the BCVA in the surgery eye, and the WMAR (all P<0.001). Greater increases in the CLVQOL composite scores was associated with superior preoperative WMAR (odds ratio: 9.920, P<0.05), and age below 60 years (odds ratio: 9.905, P<0.05).

Conclusions: Cataract surgery should be recommended for advanced glaucoma patients with stable intraocular pressure.
