Lens repositioning is surgery to move a natural or artificial lens back into the correct position when it has shifted. It is performed when decentration or dislocation affects vision or threatens eye health.
When It Is Needed
Causes include zonular weakness in conditions like pseudoexfoliation, trauma, or complications after cataract surgery. A displaced intraocular lens can cause blur, glare, double vision, or raised eye pressure.
- Options include suturing the lens to the iris or sclera, rotating a toric IOL, or placing a new lens in a more stable location
- Choice depends on the type and position of the existing lens
- Sometimes combined with vitrectomy if the lens has fallen backwards
- Risks include retinal detachment, inflammation, and further dislocation
Outcomes
Successful repositioning can restore stable vision and reduce symptoms. Careful planning and imaging help minimise complications.
- Post-operative drops control inflammation and pressure
- Follow-up checks lens position, refraction, and retinal status
- Glasses or minor laser touch-ups may still be needed
- Underlying causes such as trauma or connective-tissue disease should be addressed
