Abstract

СПОСОБ МАРКИРОВКИ ОПТИЧЕСКОГО ЦЕНТРА РОГОВИЦЫ, предусматривгшндий совмещение коллимированного светового луча с оптической осью глаза, отличающийс  тем, что, с целью упрощени  способа, световой луч направл ют в глаз через непрозрачную контактную линзу с отверстием в центре при соотношении диаметра отверсти  и толщины линзы в центре 1:4, а оптический центр роговицы определ ют при попаданий луча на макул рную область.A METHOD OF MARKING AN OPTICAL CENTER OF CORNEY, provided for combining a collimated light beam with the optical axis of the eye, characterized in that, in order to simplify the method, the light beam is directed into the eye through an opaque contact lens with a hole in the center at a ratio of hole diameter and lens thickness in center 1 : 4, and the optical center of the cornea is determined when the beam hits the macular area.
