Is it normal to see floaters and flashing lights after cataract surgery?

✓ Accepted answer

It is relatively common for patients to notice new floaters or mild flashing lights shortly after cataract surgery, but these symptoms can also signal a serious retinal detachment that requires immediate attention.

• Sudden changes require emergency care: If you see a shower of new floaters, a dark curtain covering part of the vision, or frequent flashes, contact an ophthalmologist immediately. These are hallmark signs of a retinal tear or detachment.
• Post-operative inflammation: In the first few weeks, mild posterior vitreous changes can occur as the eye heals. The American Academy of Ophthalmology notes that while some visual disturbances are expected, persistent flashes warrant a dilated eye exam to rule out retinal issues.
• Monitor for pain or redness: If the flashes or floaters are accompanied by eye pain, significant redness, or a sudden decrease in visual acuity, seek care right away. These symptoms may indicate an intraocular infection (endophthalmitis) or other complications.
• Keep all follow-up appointments: Ensure your father attends his scheduled post-operative checks. If his baseline clinic notes do not align with his current symptoms, request a retinal evaluation specifically to check the back of the eye.
• Understand the risk factors: Older adults and those with a history of nearsightedness are at higher risk for retinal problems. If he has a family history of retinal detachment, be even more vigilant about reporting new symptoms to his care team.
