Prevalence and risk factors on age-related cataract and surgery in adults over 50 years old in Binhu District, Wuxi, China

摘要

AIM:To investigate the prevalence and risk factors of age-related cataract(ARC),ARC surgery procedures,and postoperative vision results among adults over 50 years old in the Binhu District of Wuxi City,China.METHODS:Thirty basic sampling units were analyzed via a cluster random sampling method.Detailed medical histories were collected and eye examinations were performed.Cataract prevalence and surgical procedures were quantified.RESULTS:Among the 6150 participants,1421 cataract cases were diagnosed and prevalence was 23.1%.The prevalence of cortical,nuclear,and posterior subcapsular cataracts increased with age(P0.05).The odds ratio of cataract patients who had or did not have cataract surgery was 3.15(87/28)and the frequency of cataract blindness surgery was 75.7%(87/115).Poor visual outcomes was in 107 eyes(40.7%)after cataract surgery.Poor vision was mostly caused by uncorrected reflective errors(30.9%)and ocular comorbidities(41.1%).The prevalence of cataract surgery complications was 5.7%(15/263).Surgical complications and posterior capsular opacification were avoidable factors facilitating poor vision.CONCLUSION:ARC,especially in females and illiterateindividuals,presents a public health problem in this district.Poor visual outcomes after cataract surgery are frequent.High-quality cataract surgeries and treatment of ocular comorbidities are vital.
