DEVICE FOR CONTACT TRANSSCLERAL EYE IRRADIATION AND METHOD OF APPLICATION AT PHOTODYNAMIC THERAPY OF INTRAOCULAR NEOPLASMS Russian patent published in 2009 - IPC A61F9/08 A61N5/67 

FIELD: medicine.

SUBSTANCE: said device contains a transparent cylindrical support case, a retainer ring and a lock nut. The support case comprises a necked top with an external thread and a light guide port, and a hollow bottom with a circular marking edge at the end face. When the device is applied for photodynamic therapy of intraocular neoplasms, the marking edge is covered with brilliant green. The device is mounted with its end face of the bottom with a marking edge on sclera exposed to contact transscleral laser irradiation herewith covering the adjacent fields by 15-20% of the area through sequential relocation of the device from periphery to the middle within projection of tumour base on sclera and covering 2 mm of adjacent tissues.

EFFECT: application of group of inventions provides limitation of the area of one laser radiation spot in specified dimensions, herewith maintaining constant distance of the light guide end face to irradiated surface within procedure, accurate visualisation of the irradiated sites, with limiting the area of a laser irradiation by desired region.
