Purpose. To develop a method of standard corrections to the optical part of artificial iridolenticular diaphragm, depending on its various fixation options in the eye. Material and methods. The results of 155 iridolenticular diaphragm implantations with various fixation options were analyzed: 69 cases had intracapsular fixation, 28 – anterior capsule fixation, 58 – ciliary sulcus fixation. Results. As a result of the gained experience of implantations, the values of A-constants were obtained, calculated according to the Holladay method: for intracapsular fixation – 118.40; anterior capsule fixation – 117.90; ciliary sulcus fixation – 117.55; iris-claw fixation – 116.7. Then the corrections to the optical part of artificial iridolenticular diaphragm, depending on its various fixation options in the eye, were calculated (using Holladay). Conclusion. Thus, it is possible to improve the calculation of the strength of the optical part of artificial iridolenticular diaphragm, depending on its fixation method, by creating a correction algorithm in accordance with artificial iridolenticular diaphragm position.
