摘要:
FIELD: medicine.SUBSTANCE: group of inventions relates to medical equipment. In generation of setting guide pre-surgical biometrical information, associated with eye, in which implanted intraocular lens (IOL) is to be installed, is collected, and optical power of torus lens and direction of torus lens axis in eye are calculated. Said information represents information for obtaining eye image, measurement of corneal topography for obtaining steep axis, from which direction of torus lens axis is calculated, and obtained from input data, applied for determination of eye center. Said information is transmitted to program of IOL calculation, position and direction of IOL in eye are calculated and generated is setting guide, which contains eye image, obtained during preoperational tests and on which surgeon can depend during IOL implantation operation to determine cut position and proper centering and orientation of IOL. Console of crystalline lens removal contains input port for reception of said information, module of processing and connected with it memory unit, connected to input port. Module of procession is made with possibility to carry out program of IOL calculation, made with possibility of calculating position and orientation of IOL in eye and generating setting guide.EFFECT: application of group of inventions makes it possible to increase accuracy of placement and orientation of IOL in eye due to provision of feedback during operation, based on pre-operation eye images.12 cl, 7 dwgГруппа изобретений относится к медицинской технике. При генерации установочного направителя собирают предоперационную биометрическую информацию, связанную с глазом, в который должна быть имплантирована интраокулярная линза (ИОЛ), и вычисляют оптическую силу торической линзы и ориентацию оси торической линзы в глазу. Упомянутая информация представляет собой информацию для получения изображения глаза, измерений топографии роговицы для получения крутой оси, из которой вычисляют ориента
