High-viscosity eye lotions

摘要

The invention presents a high-viscosity eye lotion with which lasting curative effects can be obtained with no feeling of foreign bodies to the eye as in the conventional eye salves used in treating eyes. The high-viscosity eye lotion of the invention comprises a swollen hydrated gel of a crosslinked polyvinyl alcohol and an eye-disease curative active ingredient contained therein. It is prepared by irradiating an aqueous solution of a polyvinyl alcohol with an ionizing radiation to such an extent that the polyvinyl alcohol is crosslinked to give a hydrated gel with an equilibrium swelling ratio in the range from 70 to 100 by weight and then dipping the hydrated gel in an aqueous solution of the eye-disease curative active agent.
