Introduction: The current cataract surgery requires the restoration of vision in the highest quantity and quality possible.

Methodology: A prospective and analytical study of a series of cases was carried out in 590 patients with the diagnosis of bilateral cataract, operated by simultaneous bilateral lens surgery, treated at the Ocular Microsurgery Center of the Cuban Institute of Ophthalmology "Ramón Pando Ferrer”, During the period from September 2018 to July 2020. The variables of age, sex, nuclear hardness according to LOCS III, better visual acuity with and without correction, medium induced astigmatism, color vision, contrast sensitivity and reading speed analysis. Percentages and absolute numbers were used to summarize the qualitative variables; in the case of the quantitative ones, the mean with its standard deviation (SD) and the 95% confidence interval were used.

Results: The female sex was more frequent in 68%, the mean age was 70.1 ± 7.3 years. The 53.01% of the patients had NO3 hardness. The mean of the best visual acuity without correction improved to 0.86 ± 0.23, the BBCVA improved to 0.98 ± 0.02; the rest of the variables studied showed in the same way significant improvement.

Conclusions: The simultaneous bilateral cataract surgery contributes significantly to the improvement of binocular vision in quantity and quality in the same time.
