CALCULATION OF INTRAOCULAR LENS (IOL) OPTICAL POWER IN ACCORDANCE WITH DIRECTLY SPECIFIED IOL POSITION Russian patent published in 2017 - IPC A61B3/10 

FIELD: medicine.

SUBSTANCE: intraocular lens (IOL) optical power calculation involves determination of the eye parts positions along the eye axis. These positions include cornea position, front and back positions of the lens and retina position. IOL position is calculated in accordance with the anterior and posterior positions of the lens. Also the data about the cornea are determined. IOL optical power is calculated using the data on the cornea, IOL position and retina position. In some embodiments, for the segments of the said axis, the refractive indices are determined and at least one position is adjusted in accordance with the specified refractive indices.

EFFECT: proper vision correction.
