Official Title: Ultrasound Biomicroscopic Assessment of Intraocular Lens Tilt and Decenteration After Phacoemulsification
Brief Summary: This study aims to assess intraocular lens (IOL) tilt and decenteration by means of ultrasound biomicroscopy after phacoemulsification.
Detailed Description: Ultrasound biomicroscopy (UBM) is a non-invasive technique that uses high-frequency ultrasound to image the anterior segment of the eye.

It can help as a diagnostic procedure in eyelid and anterior segment (cornea, conjunctiva, sclera, iris, ciliary body) pathology. It is a vital tool in evaluating anterior segment cysts or tumors and their diagnosis, evolution, and treatment.

IOL tilt and decentration could be secondary to various aetiologies. The extent and direction of preoperative crystalline lens tilt have been demonstrated to be strongly correlated with postoperative tilt. Asymmetrical IOL fixation (partly in bag and partly in sulcus) and capsular tear during capsulorrhexis were reported as some causative factors to IOL tilt and decentration.
