[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.
