Abstract:
We report removal of a retained broken chopper tip after phacoemulsification. Although the foreign body was thought to be stable in the ciliary sulcus 2 months postoperatively, it dislocated into the anterior chamber 8 months later. It was removed with a microforceps under gonioscopic visualization. Although previous reports suggest that retained metallic fragments after phacoemulsification can be left in place if they are difficult to access and appear stationary, our case highlights the potential for long-term instability. We therefore recommend consideration of surgical removal with the use of gonioscopic, endoscopic, or posterior segment visualization systems, as required.
Insights
A broken phacoemulsification chopper tip retained in the eye dislocated months later. Surgical removal is recommended due to potential long-term instability of retained intraocular fragments.
Area of Science:
- Ophthalmology
- Surgical Innovation
Background:
- Phacoemulsification is a common cataract surgery technique.
- Retained intraocular foreign bodies can occur, posing potential risks.
Observation:
- A metallic chopper tip fractured and remained in the ciliary sulcus post-phacoemulsification.
- The fragment, initially stable, dislocated into the anterior chamber 8 months later.
Findings:
- The dislocated chopper tip was successfully removed using microforceps and gonioscopic visualization.
- This case demonstrates that retained metallic fragments may not remain stable long-term.
Implications:
- Surgical removal of retained fragments should be considered, even if initially appearing stable.
- Advanced visualization techniques like gonioscopy or endoscopy may be necessary for safe removal.
