The binocular confusion in unilateral aphakia.

The first 4 symptoms of binocular confusion concern primarily daytime vision and the fifth symptom concerns nighttime vision. Even with a conventional contact lens correction, symptoms of binocular confusion occur, especially with high optical aniseikonia for near or far distance. In addition, diplopia occurs in the presence of strabismus. The important result of our research is the fact that unilateral aphakes are severely disturbed by the 5 symptoms of binocular confusion described above. These disturbances can be eliminated completely with an appropriate spectacle-contact lens combination based on echometry and intraocular optics.
