Foreign body removal from Eye
What is a foreign body in the eye?
Types of the foreign body:
Ocular Foreign Body Removal Technique:
Let’s discuss one by one:
- Irrigation of eye
- Finding the foreign body Position, location and depth and sweeping it.
- Removal of F.B. in OPD under Topical anaesthesia in slit lamp.
- Removal of a foreign body under local anaesthesia/ GA in an operating microscope.
1. Irrigation of eye:
Irrigation with 3-4 liters of normal saline may be adequate in acid exposure if pH is maintained at neutrality 30 minutes after completion of irrigation. In alkaline exposures, irrigation may be required for 24 hours. The safest method is a careful irrigation of the eye with a stream of sterile saline, directed from the sclera over the cornea. It is important to evert the lids and irrigate both superior and inferior fornices.
2. Finding the F. B. Position, location and depth and then sweeping it
Sweeping the palpebral conjunctiva will often relieve the symptoms even if the foreign body is not directly seen.

4. Removal of a foreign body under local anaesthesia/ GA in operating microscope
Note: Always check the patient’s TETANUS immunization status.
If the foreign body is iron-based, follow up is needed because of a propensity to form a RUST RING.
