METHOD OF SELECTING PARAMETERS OF LASER EXPOSURE IN TREATING FAR-REACHING AND TERMINAL REFRACTORY GLAUCOMA Russian patent published in 2019 - IPC A61F9/08 A61B5/107 A61B8/10 

FIELD: medicine.

SUBSTANCE: invention refers to medicine, namely to ophthalmology, and can be used for selecting laser exposure parameters in treating far-reaching and terminal refractory glaucoma. Ciliary body thickness in mm is measured by ultrasonic biomicroscopy. Laser applicants are applied at equal distance from each other by diode laser by contact-transscleral method in continuous mode with wavelength of 810 nm. Applications are applied at 2–3 mm from the limb along circumference by 360 degrees, avoiding positions at 3 and 9 o'clock. If the ciliary body thickness is 0.4 mm or less, the power of one laser exposure pulse is 0.8–1.2 W. If the ciliary body thickness is more than 0.4 mm and less than 0.6 mm, the power of one laser exposure pulse is greater than 1.2 W and less than 1.8 W. If the ciliary body thickness is 0.6 mm or more, the power of one laser exposure pulse is 1.8–2.2 W. Number of applicants at all thicknesses of ciliary body 18–22. Exposure time 4 sec.

EFFECT: method provides stable normalization of intraocular pressure in postoperative period, preservation of residual visual functions in patients with far-away refractory glaucoma, withdrawal of pain syndrome in patients with terminal painful glaucoma, reduced risk of postoperative complications, and also increases convenience of surgeon due to selection of parameters of laser exposure depending on thickness of ciliary body.
