Aim of the Study:

To present and compare treatment results in patients who underwent PPV due to intraocular foreign body (IFB) with or without previous electromagnet IFB extraction.

Material & Methods:

Retrospective analysis of IFB patients – with IFB in the vitreous or on the retinal surface. 10 patients (group A) underwent PPV without electromagnet extraction of a foreign body. 2 patients (group B) were referred to our department after electromagnet IFB extraction in other departments. Standard ophthalmic examination including best corrected visual acuity (BCVA) was performed before and after surgery. Morphology of the retina was assessed by means of optical coherence tomography (OCT Stratus III, Zeiss Meditec, USA).


Mean observation period – 12.6 +/- 9.3 months. 8 patients underwent simultaneous cataract surgery and IFB removal. BCVA before surgery – light perception (3 patients), hand movement (2 patients), 0.1-0.2 (3 patients), 0.3-0.5 (3 patients), 1.0 (1 patient). Mean BCVA 1 month after surgery in a group A – 0.7 (range: 0.5-1.0). In group B BCVA after surgery remained low – light perception (1 patient) and 0.01 (1 patient).


Electromagnet IFB extraction is still in use, although it can result in ocular tissue damage. Results of our study show that it should be avoided. PPV in IFB patients is a procedure of choice and it enables to achieve satisfactory BCVA and retinal morphology.
