Intraocular foreign body (IOFB) injury is a common potentially serious form of ocular trauma. Metallic IOFB is the most common type of IOFB injury. Apart from the associated ocular tissue damage, Metallic IOFB may cause permanent visual impairment due to retinal toxicity and endophthalmitis.

When presenting posteriorly, the approach of IOFB removal is challenging. Several techniques had been described for posterior IOFB removal. All of these techniques aimed to remove IOFB with the least possible collateral damage. This study aims to describe "Iris shelf" technique for posterior IOFB removal through a clear corneal incision combined with phaco-vitrectomy and report its outcomes.

Inclusion Criteria:

- posterior segment metallic IOFB who underwent combined phacovitrectomy with IOFB removal through a clear corneal incision using "Iris shelf" technique

Exclusion Criteria:

• Any other surgical technique for posterior segment IOFB removal

patients with posterior segment metallic IOFB who underwent combined phacovitrectomy with IOFB removal through a clear corneal incision using "Iris shelf" technique at Assiut University hospitals and Al-Forsan eye center, Assiut; Egypt in the period between January 2016 and December 2019.
