FIELD: medicine, pharmaceutics.

SUBSTANCE: invention relates to suspension for visualisation of transparent tissue of eye, which contains finely dispersed particles of biodegradable macromolecular compound and salt, selected from salt of divalent metal in amount 0.1-1 wt/vol.% or salts of trivalent metal in amount 0.01-1 wt/vol.%. Said suspension is intended for pouring into eye to come in contact with transparent eye tissues with the purpose to improve their distinguishability. Invention also relates to ophthalmologic preparation which contains hard particles of biodegradable macromolecular compound and water medium, which contains said salts of divalent or trivalent metal, solid and water media being placed separately and without allowing contact with each other. Invention also relates to methods of obtaining suspension for eye visualisation, which include obtaining solid composition, containing finely dispersed particles of biodegradable macromolecular compound or finely dispersed particles of biodegradable macromolecular compound and 0.1-1 wt/vol.% of salt of divalent or 0.01-1 wt/vol.% of salt of trivalent metal, and suspending said solid composition in water solution.

EFFECT: invention ensures obtaining suspension for visualisation of transparent eye tissue, which can be applied as convenient and safe means for improvement of distinguishability of transparent eye tissues when performing surgical operation on them.
