Resumen

PEREZ CANDELARIA, Eneida et al. Effective position of the intraocular lens according to the ultrasound biomicroscopy and visual results in patients operated on from cataract. Rev Cubana Oftalmol [online]. 2010, vol.23, suppl.2, pp.721-733. ISSN 0864-2176.

OBJECTIVE: To determine the correlation between the effective positioning of the intraocular lens in the posterior chamber using ultrasound biomicroscopy and the visual results achieved in patients operated on from cataract. METHODS: Prospective, cross-sectional and descriptive study was conducted in «Ramón Pando Ferrer» Cuban Institute of Ophthalmology from January to June 2007, in which variables such as age, sex, etiology of the cataract, location of the intraocular lens using ultrasound biomicroscopy, spheral equivalent, refractive results and postoperative visual acuity were analyzed. RESULTS: Most of the patients were 60 to 79 years-old, females prevailed and senile cataract was the most common type (74%). In 68% of patients, ultrasound biomicroscopy located the intraocular lens in the capsular sac whereas half of the operated eyes presented some error in the postoperative refractive results. CONCLUSIONS: Differences between the various locations of the intraocular lens were found but they were statistically significant in the type of cataract, the spheral equivalent of the postoperative refraction and in the postsurgical refractive results. There were no differences between the site of implantation of the IOL and the achieved visual acuity.

Palabras clave : Ultrasound biomicroscopy; spheral equivalent; effective position of the lens.
