The cornea is the protective clear membrane that covers the pupil and the iris in your eye. Abrasions (a scratch) to the cornea are common, possibly by things like a hairbrush, a fingernail or a tree branch. Dust particles that hit the eye can cause scratches, as can anything that becomes lodged under your eyelid.
A corneal abrasion usually heals on its own and the pain settles over 24-48 hours. But your eye may feel gritty for several weeks. An eye infection could develop following a scratch to the cornea. As a precaution you might be prescribed antibiotic eye drops or ointment for several days to prevent this. You may also be prescribed a pupil dilating drop, to stop the painful spasms of the iris. Occasionally, an eye pad may be applied for several hours.
Anaesthetic drops are used to numb your eye during your eye examination. They are not prescribed to take home as they will slow corneal healing if used regularly. Please remember that the pain will come back once the anaesthetic has worn off, usually after 20 to 60 minutes.
Wear sunglasses to help reduce light sensitivity
Avoid rubbing or touching your eye
You may also be advised to use lubricants (artificial tear drops or ointment) to help keep your eye moist while it heals, these can often be bought over the counter in supermarkets or pharmacies.
Avoid wearing contact lenses until your eye is completely healed. This is usually between 2 and 4 weeks.
Simple analgesics can be used after corneal abrasions, most of which can be bought over the counter in shops, supermarkets or pharmacy’s. Examples are:
You may have been prescribed an alternative pain killer, please refer to specific advice for that tablet if this is the case.
You will not need to return for a further check-up. If your eyesight becomes more blurred or the pain and redness get worse, contact your GP or contact NHS 111. If you feel this is an emergency then attend your local Emergency Department.
