Intraocular Lens Decentration and Tilt after Combined Phacoemulsification and Pars PlanaVitrectomy

Abstract

Abstract: : Purpose: To assess the decentration and tilt of intraocular lens (IOL) after combined phacoemulsification (PEA) with IOL implantation and pars plana vitrectomy (PPV). Methods: The results of combined PEA with IOL and PPV in fifteen eyes of fifteen patients (PPVgroup) were retrospectively analyzed with the decentration and tilt of IOL. Fourteen eyes of fourteen patients with only PEA and IOL implantation served as controls (IOL group). Both the length of the decentration and the degree of the tilt of the IOL were measured using the Anterior Eye Segment Analysis System (EAS–1000) after surgery. Results: The IOL decentration in PPV group was significantly grater than in the control group (P=0.016, Student’s t–test). The IOL tilt was also significantly larger in PPV group than in the control group (P=0.049). Conclusions: Both IOL decentration and tilt was larger in the eyes after combined PEA with IOL and PPV than in only PEA with IOL eyes.In these results, IOL decentration and tilt seems to influence visual function after combined PEA with IOL and PPV.
