Summary
Metallic fragments in the eye after cataract surgery were observed. These fragments, likely from instrument contact during phacoemulsification, caused no immediate visual issues.
Area of Science:
- Ophthalmology
- Surgical Technology
Background:
- Cataract extraction using phacoemulsification is a common procedure.
- Intraocular foreign bodies can potentially affect visual outcomes.
Purpose of the Study:
- To investigate the occurrence and potential source of intraocular metallic-appearing foreign bodies after cataract extraction.
- To determine if instrument contact during phacoemulsification contributes to fragment generation.
Main Methods:
- Observation of six eyes with intraocular foreign bodies post-cataract extraction.
- In vitro experiment applying ultrasound power to surgical instruments.
- Microscopic examination of instrument tips and generated fragments.
Main Results:
- Metallic-appearing foreign bodies were found in the anterior segment of six eyes after two-handed phacoemulsification.
- Experimental simulation produced similar foreign bodies from instrument-tissue contact.
- Surface irregularities on surgical instruments suggest a source for these fragments.
Conclusions:
- Instrument contact during phacoemulsification may lead to intraocular metallic fragments.
- The observed fragments did not cause immediate visual impairment.
- Long-term follow-up is necessary to assess the clinical significance of these fragments.
