Способ определения оптической силы отрицательной заднекамерной интраокулярной линзы, включающий определение величины исходной близорукости, отличающийся тем, что при расфокусировке ретинального изображения определяют границы фокусной зоны и величину диоптрийности, соответствующую первому максимальному значению остроты зрения на схеме расфокусировки, из которой вычитают 1,5 Dптр, причем при несоответствии полученной величины границам фокусной зоны за оптимальное значение выбирается диоптрийность, соответствующая на схеме расфокусировки остроте зрения 0,25.A method for determining the optical power of a negative posterior intraocular lens, including determining the magnitude of the initial myopia, characterized in that when defocusing the retinal image, the boundaries of the focal zone and the diopter value corresponding to the first maximum value of visual acuity in the defocusing circuit are subtracted from which 1.5 D mt is subtracted moreover, if the obtained value does not correspond to the boundaries of the focal zone, the dioptricity corresponding to the split-off diagram is selected for the optimal value syphi visual acuity 0.25.
