About this procedure
A superficial particle may feel like sand under the eyelid and produce pain on blinking, tearing or sensitivity to light. The exact circumstances matter: a particle from a windy street is not equivalent to metal propelled by a grinder or other power tool.
Clinical features
A high-velocity impact may cause penetrating injury even when the object appears tiny or external damage seems limited. A chemical splash is a separate emergency requiring immediate irrigation. Do not press, rub or patch an eye when penetration is suspected, and never try to remove an embedded object with tweezers or other tools.
Important differences and warning signs
The ophthalmologist first evaluates visual acuity and examines the ocular surface, potentially with a slit lamp and dye to reveal a corneal abrasion. The assessment determines whether removal is safe on an outpatient basis or whether an emergency ophthalmic service is needed.
Assessment and individual care
If a body is confirmed to be superficial, a clinician may remove it with appropriate anaesthesia and equipment and provide aftercare instructions. Antibiotic or other treatment is used only when indicated. Availability of removal at a particular clinic is confirmed after assessment, never guaranteed online.

Signs and symptoms
- Sudden foreign-body sensation, tearing and pain with blinking.
- Redness, difficulty keeping the eye open or marked light sensitivity.
- A history of metalworking, drilling, grinding or possible high-speed impact.
Diagnosis and tests
Visual acuity and slit-lamp examination help locate the object and assess corneal damage. Suspected penetration requires urgent specialised assessment.
Care and treatment approaches
Only a clinician should remove a superficial embedded particle. Do not rub, dig into, or press on the eye; follow injury-specific aftercare.
When to seek urgent care
High-speed metal impact, possible penetrating trauma, sudden visual loss or intense pain requires emergency eye care: call 103. For a chemical splash, start immediate copious water irrigation while help is arranged; do not delay irrigation for a booked visit.
Frequently asked questions
Can I remove metal fragments with tweezers?
No. High-speed metal may have penetrated the eye, and attempting removal can cause further injury; urgent specialist assessment is needed.
Is the object removed before an examination?
No. The clinician first establishes the depth and type of injury and decides whether the case is safe for local removal.
What should I do after a chemical splash?
Begin rinsing the eye with plenty of clean water immediately and seek emergency medical care; do not wait to arrange a routine consultation.
