MARRERO RODRIGUEZ, Ernesto; SANCHEZ VEGA, Osmar; BARRERA GARCES, Blanca Rosa  and  VALDES BOZA, Dania. Cataract surgery contraindications for patients from Maracaibo municipality. MEDISAN [online]. 2011, vol.15, n.2, pp.228-233. ISSN 1029-3019.

A descriptive and cross-sectional study of 76 patients with cataract, who could not be surgically treated at the Ophthalmological Center from Maracaibo municipality, belonging to Zulia State (Venezuela), was carried out from June to July, 2009 in order to identify the main causes that were contraindicating the ophthalmopathy surgery, for which each participant's eye was examined. The 60-69-year-old age group and male sex, as well as the visual sharpness under 0,3 and pre-surgical diagnosis of senile cataract, were predominant in the case material. Macular degeneration associated with age prevailed as the most frequent disease invalidating the surgery, giving some priority to nuclear lenticular opacity according to morphological classification. It was concluded that opacity of crystalline lens does not always cause bad vision, thus it is necessary to carry out a detailed ophthalmological test.
