Risk factors of low improvement of vision health related quality of life after cataract surgery

Abstract

Objective To investigate the risk factors of low improvement of vision health related quality of life(VRQoL)after cataract surgery for improving surgical care for patients.Methods A total of 258 patients underwent cataract extraction were evaluated for preoperative and 3-month postoperative VRQoL in a public hospital in Shanghai.Data associated with the VRQoL changes including the patients'characteristics,unilateral or bilateral cataract extraction,visual acuity improvement,systemic or ocular comorbidities,and surgical complications were analyzed.Results Patients with surgical complications,ocular and systemic comorbidities had lower VRQoL scores improvement(P=0.016,0.172,0.166).Preoperative VRQoL scores,the change of visual acuity,and ocular comorbidities were the independent risk factors of VRQoL scores change of unilateral cataract extraction patients(P=0.000,0.032,0.036).Preoperative VRQoL scores,preoperative visual acuity,the change of visual acuity,and surgical complications were the independent risk factors of VRQoL scores change of bilateral cataract extraction patients(P=0.000,0.000,0.000,0.024).Conclusions In a cohort of Shanghai veterans with heavy preoperative comorbidities burden,high preoperative VRQoL,low change of visual acuity,high preoperative visual acuity,and surgical complications are risk factors of low VRQoL improvement after cataract extraction.
