[Posttraumatic unilateral aphakia and contact lens -binocular functions of grown-ups].

The binocular results are only subnormal and comparable to former squinting patients. The results are better if one succeeds in reaching a visual acuity of at least 1.0. One can try to prevent a divergence by prescribing a contact lens as early as possible. Presbyopic patients have better binocular functions because the lost accommodation is the most interfering component (factor). It has disadvantageous effects especially on those patients who are yet presbyopic. The aniseikonia is in contrary to this not an as important interfering factor.

[Delayed healings of the epithelium of the cornea due to soft lenssolutions].

Six different soft lens solution have been tested to investigate their effect on the healing process of a corneal erosion, experimentally scratched in rabbit-cornea. Healing delays have been observed in every cases; also by three medicaments which are used for "dry" eyes. The latter ones should never have a conjunctival application. Theexplanation of those healing delays is given by the concentration properties of HEMA-lenses for disinfectants. The admixtures of soft lens solutions like buffers and liquid polymerscause and additive effect on retardment of coeneal regeneration.
