Clinical Study on Relationship of Biometry Measuring and Intraocular Lens Power

Cui Dongmei Xu Xiaoyi Li Yun Xiao Ying Mao Ruihe (Department of Ophthalmology,The Second Hospital of Shandong University,Jinan 250033)  
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.
