Introduction: The cataract surgery through small incision technique is a procedure with which the postoperative refractive defects have decreased. Objective: To characterize the patients with astigmatism induced by the cataract surgery through a tunnelled approach compared with the value of post-surgical astigmatism. Methods: A descriptive and prospective study of 74 surgically treated cataract patients was carried out in "Dr. Salvador Allende" Ophthalmological Center from Havana, during the quarter September-December, 2009. Results: Ages from 60 to 69 years (52.7%) and the female sex (52.7%) prevailed in the series. Average preoperative astigmatism was 1.00 diopters and the postoperative one increased to 1.50 diopters, indicating an average induced astigmatism of 0.50 diopters 3 months after surgery. The postoperative visual acuity increased from 0.6 to 1.0 in 71.6% of the patients. Conclusions: The average value of induced astigmatism evidenced a not significant increase, if keeping in mind that the value obtained after a cataract surgery was not considered pathological.
