Pain and Blurred Vision After Eye Surgery or an Injection: Act Quickly

Quick answer

Endophthalmitis is a serious infection inside the eye that can occur after surgery, an injection or a penetrating injury. Increasing pain, marked redness or worsening vision after a procedure needs immediate contact with the surgeon or emergency eye care, even if a follow-up is soon. Do not wait until tomorrow or use old drops.

Which symptoms should raise concern?

A procedure may cause mild discomfort or blur that your surgeon has explained, but worsening rather than improving vision, increasing pain, redness, discharge or strong light sensitivity are different. Many new floaters or a curtain also need urgent contact with your care team.

Does every blur after a procedure mean infection?

No. Vision can fluctuate during expected recovery, and infection is not the only cause of pain or redness. But the difference cannot be safely judged at home, especially after an intraocular procedure or injection. Follow your instructions and call promptly for new or worsening symptoms.

How is it assessed?

The ophthalmologist checks vision and both the front and back of the eye for internal inflammation, and may need imaging or a small sample to identify the organism. Do not wait for a test result before seeking care; prompt examination and treatment matter for sight.

How is it treated?

Treatment may include an antimicrobial injection into the eye and, in some cases, sampling or surgery to remove part of the vitreous. The team chooses the medicine and timing based on the examination and severity. Home treatment or delaying contact may allow the infection to worsen.

Who should I contact, and when?

Call the surgeon or center that performed the procedure and give the procedure type, date and new symptoms. If you cannot reach them quickly, or vision is declining or pain is severe, go to emergency eye care. Do not drive yourself if vision is unsafe.

Frequently asked questions

How long should I wait before calling after surgery?

Call immediately for worsening vision, increasing pain or marked redness. Do not wait for the follow-up appointment.

Does endophthalmitis only happen after an injection?

It can follow an eye injection, surgery or penetrating injury, but it is not the usual outcome of a procedure.

Can I use leftover antibiotic drops?

Do not use old drops instead of contacting the surgeon urgently; treatment may require an injection inside the eye.

Can mild blur be normal after surgery?

Some blur can occur during recovery depending on the procedure, but worsening vision or increasing pain must be reported promptly.
