FIELD: medicine, ophthalmology.
SUBSTANCE: prior to intraocular lens implantation, preoperative corneal astigmatism and the axis of the strong corneal meridian are determined. Then postoperative astigmatism of refraction is determined according to the original formula: Ast = Kast x 0.71 – 0.62 x sin K2ax + 0.73, where Ast is postoperative refractive astigmatism, diopter; Kast - preoperative corneal astigmatism, diopters; K2ax is the axis of the strong meridian of the cornea, deg.
EFFECT: method provides accurate prediction of residual astigmatism during implantation of monofocal non-toric intraocular lenses.
