[Light phenomena in the dislocation of artificial lenses in a model trial].
Light phenomena evoked by a Kratz elliptical posterior chamber lens, a Mark Choyce IX anterior chamber lens, and a four-loop Binkhorst anterior chamber lens were investigated in a model with pupils of various sizes. Besides monocular diplopia, the edge of the lens produces scattered light phenomena which vary according to the type of lens as well as the size of the pupil. It makes little difference whether the beam of light strikes the surface of the lens perpendicularly or at an angle of 30 degrees. Of the three lenses tested, the four-loop Binkhorst lens caused the most intense scattered light, due to the fixation of its haptic near its center.
