Ultrasound biomicroscopy and stability of intraocular lens in patients with myopia after phacoemulsification cataract surgery

Purpose: To evaluate the stability and the refractive error of the different intraocular lens (IOL) after cataract surgery. Method: Retrospective, observational and single-center study. Patients diagnosed with cataract and myopia who underwent a phaco-emulsification surgery with intraocular lens placement without complications were included. All patients underwent a complete ophthalmological examination, ultrasound biomicroscopy was performed at 2 weeks, 1 and 3 months after surgery. Descriptive statistics were performed using measures of central tendency and comparative analyzes. A value of p < 0.05 was considered significant. Results: Thirty-one subjects with a diagnosis of axial myopia and senile cataract were included, 20 women (64.5%) and 11 men (35.5%), with a mean age was 62.8 +/- 13.14 years. The IOL displacement were not different for the upper, lower, temporal and nasal quadrants; however, we observed a tendency to inclination to the temporal sector (p = 0.054) between the first and third postoperative month. Therefore, the were no significant differences in spherical equivalent between groups postoperatively. Conclusions: The inclination of the IOL did not change over time after surgery, the changes were similar with the different three types of IOL.
