# What causes blurred vision after surgery?

Some blur after eye surgery is normal while the eye heals, but sudden or severe changes need checking.

## Expected causes of temporary blur

Swelling, healing incisions, and post-operative drops can all affect clarity for a short time. Vision often fluctuates from day to day early on.

- Ointments and thick drops can smear vision for several minutes
- Corneal swelling may cause hazy or misty sight
- Healing tissues may temporarily change your glasses prescription
- Dry eye after surgery can cause intermittent blur

## When blurred vision is a concern

Rapidly worsening blur, especially with pain or redness, may signal complications. Quick assessment helps protect the surgical result and your sight.

- Contact your surgeon urgently for sudden or dramatic vision loss
- Report new floaters, flashes, or a dark curtain over vision
- Bring all medications to your review appointment
- Do not drive until your vision meets legal standards and feels stable
