In vivo determination of the human crystalline lens shape with clinically established measurement methods
In modern cataract surgery, especially with the attempt to restore accommodation, it is desirable to obtain information on the geometrical dimensions of the human crystalline lens preoperatively to allow an adaptation of the artificial lens to the capsular bag dimensions. As the optical methods with optical coherence tomography (OCT) or slit lamp investigations yield only limited information on the equatorial lens region, high frequency ultrasound B-scan images were used for the determination of the lens cross sectional shape. Two methods for contour detection, interpolation and approximation from ultra sound images were developed: (i) a CAD method based on manual contour ...
