PEREZ CANDELARIA, Eneida de la C et al. Correlation between the location of the intraocular lens according to ultrasonic biomicroscopy and several surgical parameters in patients operated from cataract. Rev Cubana Oftalmol [online]. 2010, vol.23, suppl.1, pp. 780-493. ISSN 1561-3070.

OBJECTIVE: To determine the correlation between the location of the intraocular lens in the posterior chamber using ultrasonic biomicroscopy and the different surgical parameters in patients operated from cataract. METHODS: A prospective, descriptive and cross-sectional study was carried out in "Ramón Pando Ferrer" Cuban Institute of Ophthalmology in the period of January to June 2007. The studied variables were age, sex, etiology of cataracts, surgical technique, location of the intraocular lens using ultrasonic biomicroscopy, as well as transoperative and postoperative complications. RESULTS: Seventy nine percent of all the surgical patients were 60-79 years of age and 59 % were females. The senile cataract was the prevailing etiology for 74 % and the lens was located in the capsular sac using ultrasonic biomicroscopy in 68 % of the cases. In those eyes where the intraocular lens was off the sac, the ratio of transoperative and postoperative complications was significantly higher, whereas most of the eyes with the IOL placed in the sac did not have either transoperative or postoperative complications. CONCLUSIONS: The differences between the different locations of the intraocular lens were statistically significant in terms of the type of cataract; however, there was not any significant statistical association between the location of the intraocular lens and the surgical technique.
