Intraocular foreign bodies. Indications for lensectomy and vitrectomy

Area of Science:

• Ophthalmology
• Medical Device Technology
• Trauma Care

Background:

• Magnetic foreign bodies in the eye present significant management challenges.
• Conventional extraction methods are widely used but require careful consideration of injury severity.
• Prompt and accurate management is crucial to prevent long-term visual impairment.

Purpose of the Study:

• To review the outcomes of conventional management for magnetic foreign bodies in the eye.
• To provide guidance on the optimal timing and technique for magnetic extraction.
• To emphasize the importance of assessing posterior segment damage in relation to foreign body removal.

Main Methods:

• Review of clinical outcomes associated with conventional magnetic extraction techniques.
• Analysis of cases involving magnetic foreign bodies, categorizing by injury severity.
• Evaluation of pre- and post-extraction assessment protocols for posterior segment damage.

Main Results:

• Conventional magnetic extraction is effective when performed close to the foreign body.
• Severe open-eye injuries with large magnetic bodies necessitate immediate lensectomy and vitrectomy.
• Pre- and post-extraction assessment of vitreous hemorrhage and retinal damage is critical for guiding further management.

Conclusions:

• Conventional magnetic extraction should be prioritized for ocular magnetic foreign bodies when feasible.
• Immediate surgical intervention is essential for severe open-eye injuries involving large magnetic foreign bodies.
• Thorough assessment of posterior segment status is paramount for successful management and visual outcome prediction.
