LIGHT GUIDES FOR INTERSTITIAL LASER HYPERTHERMIA OF INTRAOCULAR NEOPLASMS AND INSERTION TECHNIQUE Russian patent published in 2009 - IPC A61N5/67 A61F9/08 

FIELD: medicine.

SUBSTANCE: light guides are inserted into neoplasm transsclerally by an adjustable lanceolate needle and cannulas 23G or 25G perpendicularly to sclera on a line of the greatest diametre of the base and on a line perpendicular diametre at the distance 2.5-3.5 mm in both sides from the centre of tumour base. The depth of light guide insertion is specified from preliminary ultrasound: tumour height at the distance 2.5-3.5 mm on sclera from the centre of tumour basis minus 1.5-2 mm.

EFFECT: possibility for controlled depth hyperthermia, minimum injury of structures and eye tissues in light guide insertion and procedure, elimination of required additional surgeries following hyperthermia, necrosis limitation by tumour volume.
