Abstract

In the current study, the CLVQOL was used to assess VRQOL before unilateral or bilateral cataract surgery and at the end of the follow-up period in order to determine the greater beneficial mode of surgery for patients, if one of the two surgical methods is more beneficial over the other. The patients were classified as receiving unilateral (group A) and bilateral cataract surgery (group B). There were no significant differences between groups A and B before the operation in terms of life quality scores, binocular weighted average LogMAR BCVA, age, educational level, gender, systematic and ocular comorbidities, and the complications of the operation. It was shown that visual acuity improved more significantly with bilateral cataract surgery than with unilateral surgery in elderly patients with a high preoperative disease burden in Shanghai city. However, the improvement in life quality was not different in patients receiving either bilateral or unilateral cataract surgery.

Highlights

Cataract is one of the common causes of visual impairment in people over 40 years old, which has a negative impact on their quality of life
The binocular weighted average LogMAR best corrected visual acuity (BCVA) was significantly increased at the end of the follow-up period in group B compared with that in group A, there was no significant improvement in the life quality between the two groups (Table 3)
The current study focused on the impact of unilateral or bilateral cataract surgery on vision-related life quality of elderly patients in China, with the objective to investigate factors influencing the improvement in the postoperative quality of life

Summary

Introduction

Cataract is one of the common causes of visual impairment in people over 40 years old, which has a negative impact on their quality of life. Both unilateral and bilateral cataract surgeries have been shown to effectively improve the visual function of cataract patients. It is important to elucidate the impact of unilateral and bilateral cataract surgeries on the improvement of visual acuity and quality of life of these patients and to determine whether bilateral cataract surgery has greater benefit over unilateral cataract surgery. The Chinese-version low vision quality-oflife questionnaire (CLVQOL) [4] was used to assess vision health-related quality of life (VRQOL) [5] before unilateral or bilateral cataract surgery and at the end of the follow-up period [6] in order to identify potential impact factors on the surgery outcome and to determine the greater beneficial mode of surgery for patients, if one of the two surgical methods is more beneficial over the other
