[Binocular confusion in unilateral aphakia (author's transl)].

The five symptoms of binocular confusion of the unilateral aphakic patient are described. In day vision, without strabismus and without correction, the image of the aphakic eye considerbly disturbs binocular vision, though the vision is less than 20/400 (first symptom). In night traffic the uncorrected unilateral aphakic patient sees very striking light circles and within those circles of glittering dots around bright light sources of cars or around blinking indicators and stoplights (fifth symptom). The five disturbing symptoms of binocular confusion can be positivity eliminated by an appropriate combination of spectacles and contact lens (combined correction) in regard to echometry and intraocular optics.
