Our objective was evaluating visual and induced corneal astigmatism behaviour in patients operated from cataract using the Blumenthal technique. We carried out a descriptive, longitudinal study on visual acuity and induced corneal astigmatism behavior in 183 eyes of patients operated of cataract using this technique at the Teaching Provincial Hospital “Comandante Faustino Pérez” of Matanzas in the period from June 2007 to June 2008. The studied variables were age, sex, kind of cataract, visual acuity, pre- and post-surgery keratometry, and also the associated ocular diseases. We used descriptive statistics techniques. The predominant age group was that from 75 to 84 years old, and the senile kind of cataract. 92,8 % of the patients improved their visual acuity after surgery while the induced astigmatism was low. Macular Degeneration related with age and Glaucoma were the ocular diseases attempting against the good post-surgery vision. The results in visual acuity of the patients operated using this technique are good and the induced astigmatism is low, guaranteeing a better recuperation and the fastest reincorporation of the patients to their daily activities.
