Total Filling of the Vitreous Cavity With a Cohesive Ophthalmic Viscosurgical Device to Support the Removal of the Intraocular Foreign Body

To evaluate the effectiveness of loading the vitreous cavity with a cohesive ophthalmic viscosurgical device in aiding the removal of the posterior segment intraocular foreign body (IOFB).Seven consecutive patients underwent a small-gauge vitrectomy due to eye trauma with the IOFB between January 2019 and December 2019. The IOFB removal was initiated after total filling the vitreous cavity with the ophthalmic viscosurgical device (Eyefill C or Bio-Hyalur Plus) to facilitate maneuvering and slow the descent in cases of the unintendedly released IOFBs. The eye examination was performed at presentation and at 1 day, 7 days, 1 month, and 3 months after surgery. The best-corrected visual acuity and intraocular pressure were evaluated.In all eyes, IOFBs were elevated into the center of the vitreous cavity and could be securely gripped while suspended in the ophthalmic viscosurgical device to allow the surgeon for successful and harmless removal. In the 3-month follow-up, the best-corrected visual acuity was 20/20 in 5 patients and 20/25 in 2 patients. In the early postoperative period, the elevation of intraocular pressure did not occur. No patient developed endophthalmitis.The authors demonstrated that this uncomplicated technique is an effective surgical option for more reliable removal of posterior segment IOFBs.
