EFFECTIVENESS OF ION-EXCHANGE EYE LENS IN THE TREATMENT OF CORNEA AND CONJUNCTIVA ACID BURN (EXPERIMENTAL STUDY)

Abstract

The article describes effectiveness of ion-exchange eye lens in the treatment of cornea and conjunctiva acid burn. Series of experiments were conducted on 18 Chinchilla rabbits. Modelling of anterior eye segment burn was performed by 50% H2SO4 instillation on eye with 120 seconds’ exposure. The animals were divided into three groups after the development of the pathological process in eye. The first group (8 rabbits/ 8 eyes) was the main group of animals which were imposed with ion-exchange eye lens on the anterior segment after anesthesia for tree times during 10 minutes. The second group (8 rabbits/ 8 eyes) was the comparison group of animals which received daily conservative treatment. The third group (2 rabbits/ 2 eyes) was the group of model disease. Eyes of all groups were enucleated on 14th day after treatment initiation. It was found that the use of ion-exchange eye lens in the treatment of the cornea and conjunctiva acid burns (II degree) contributed to reduction of corneal damage and post-burn inflammation.
