The objective of this study was to investigate which of the previously exposed formulations has obtained the greatest range of eyes with a residual below 0.50, 0.75 and 1.00 diopters of refraction when implanting the Asqelio® Trifocal lens: Bispherical acrylic lens with posterior diffractive design, with a total diameter of 13mm and a diameter of the optical zone of 6mm. 15 rings in 4.5mm of optical zone and addition in near +3.30D and intermediate +2.20D. Hydrophobic acrylic material with Abbe number 50 and spherical aberration -0.27. Optimized constant of 119.3.

A cross-sectional observational design was carried out from data collected in the medical records of 365 patients operated on for cataract at the Oftalvist center in Almería between January 2021-September 2022. 

Only one eye of each patient was selected. The inclusion criteria were: patients without previous corneal refractive surgical procedures, without previous corneal diseases, without a history of previous intraocular surgery and without retinal abnormalities.
Patients were classified according to axial length (AL) into three groups: AL ≤22 mm (39 eyes), 22<AL<25 mm (264 eyes), and AL≥25 mm (62 eyes) following the methodology of published electronic standards. (9).

In the AL<22mm group, the formula with the lowest percentage of eyes within the range of ±0.5 was the SRK/T formula.
In the 22<AL<25 mm group, both the Holladay I formula and the Hoffer Q formula had the best percentage of eyes within the range of ±0.5.
In the group with AL≥25 mm, the best results were obtained with the SRK/T, Hoffer Q and Holladay 1 formulas.

There is not only one formula that offers good results in the implantation of the studied intraocular lens, but in general, the formula that obtained the best results was Holladay I, being the one that achieved the highest percentage of eyes below 0.50 of refractive residual.
