Nylon Suture Snare for Intraocular Foreign Body Removal: A Case Series

Area of Science:

• Ophthalmology
• Surgical Techniques
• Ophthalmic Surgery

Background:

• Intraocular foreign bodies (IOFBs) pose a significant risk to vision.
• Traditional removal methods can be complex and carry risks.
• A need exists for safe, reliable, and cost-effective IOFB removal techniques.

Purpose of the Study:

• To describe an improved snare technique for the removal of intraocular foreign bodies (IOFBs).
• To detail the materials and methods for constructing and utilizing the novel snare.
• To evaluate the efficacy and safety of this technique in clinical cases.

Main Methods:

• A snare was constructed using a 23 or 25-gauge blunt-tipped cannula, a 5-0 or 6-0 nylon suture, and a cotton-tipped applicator.
• The snare was introduced through a vitrectomy port, encircling the IOFB.
• A closed system was maintained during removal, with extraction facilitated by cannula manipulation and sclerotomy extension.

Main Results:

• The technique was successfully applied in four cases, including three traumatic IOFBs and one dislocated intraocular lens optic.
• No post-operative complications such as retinal detachment or endophthalmitis were observed.
• The snare demonstrated effectiveness in grasping both typical and irregularly shaped or large IOFBs.

Conclusions:

• The improved snare technique provides a safe, reliable, and cost-effective method for IOFB removal.
• Maintaining a closed system ensures stable intraocular pressure and visualization during the procedure.
• The technique is versatile, capable of handling various types and sizes of intraocular foreign bodies.
