The application of hard contact lenses in patients with congenital nystagmus.

From 1973 to 1987, 210 contact lenses were fitted in 112 patients with nystagmus and a refraction anomaly. In 79%, it was possible to correct myopia or a myopic or mixed form of astigmatism. In these cases, the visual acuity improved significantly. The hard contact lenses were well tolerated in all patients, and the intensity of the nystagmus can be reduced through this treatment.
