Cataract is a cause of visual deterioration in quantity and quality, surgery is the only solution to cure this disability. A prospective and analytical study of case series was carried out in 43 eyes of patients, diagnosed with cataract, operated by the phacoemulsification technique by Pre Chop with implantable intraocular folding lens, at the Cuban Institute of Ophthalmology Ramón Pando Ferrer since November 2018 until April 2020. Descriptive statistical techniques such as mean and standard deviation were used. In the non-compared results, the test used was the Chi square test, with a significance of 95%, a difference with a value of p <0.05 was considered statistically significant and the contingency coefficient to measure the strength of the relationship. The topographic and refractive changes of the cornea and their influence on the astigmatism induced after surgery were evaluated. The mean age was 69.4 ± 8.3 years, according to LOCS III 51.16% had NO3 hardness, the best visual acuity without correction in 76.75%, improved between 0.8 and 1.0, as well as the corrected vision with crystals in 93.02%; the mean keratometry pre vspost operative did not show statistically significant values (p> 0.05), the postoperative refractive cylinder in 72.09% was less than 0.5D; 51.17% of the eyes in the preoperative period had refractive astigmatism against the rule, 60.47% changed to astigmatism according to the rule one month after surgery. According to the FV-14 quality of life survey, 100% of patients had a very good quality of life one month after surgery. We conclude that with cataract surgery by personalized phacoemulsification, total efficiency is achieved in the correction of preoperative refractive defects.
