This study was conducted to evaluate the relationship between IOL power and axial length which measured by A-biometry and B-mode-guided vector A-biometry. 51 patients with age-related cataract were measured their axial length with A-biometry and B-mode-guided vector A-biometry and calculated the IOL power. Then the patients were undergone cataract surgery and implanted IOL. The IOL power were adopted the numerical values which measured by A-biometry.Optometry with computer was carried three months after operation. Results:The IOL pwoer were measured by A-biometry compared with that measured by B-mode-guided vector A-biometry.It make out that in axial length≥26mm,the numerical values which measured by two methods have distinct difference.But in 22mm≤axial length≤26mm,there are no distinct difference. It is concluded that the IOL power which calculated by B-mode-buided vector A-ultrasound has more significance than which calculated by A-biometry in age-related cataract connecting high myopia surgery.
