The quality of binocular vision in unilateral aphakia was tested in presbyopic patients. 10 of them were corrected by a contact lens, 10 by an intraocular implant. Unilateral aphakic young patients were submitted to the same tests. In the young patients the unilateral accommodation proves to be the main obstacle to binocularity. In the presbyopics there is no difference between intraocular and contact lens correction as to the quality of binocular functions. Which one of these two alternatives for the correction of unilateral aphakia should be preferred in the individual case must, therefore, be decided upon by other criteria than binocular vision. The results with unilateral spectacle correction demonstrate that binocular vision cannot be achieved by compensation of aniseikonia alone.
