Post-Cataract Surgery Floaters: Normal vs. Warning Signs of Retinal Detachment

Floaters after cataract surgery are very common and usually benign.

Why They Occur

• Vitreous syneresis (liquefaction) accelerated by surgery.
• Posterior vitreous detachment (PVD) often induced/precipitated.
• Microscopic lens fragments or inflammatory cells.

Typical Course

• Appear days to weeks post-op.
• Diminish over weeks to months as brain adapts (neuroadaptation) and vitreous settles.
• No treatment needed.

Red Flags → Urgent Ophthalmology

• Sudden shower of new floaters.
• Flashes of light (photopsia), especially temporal.
• Curtain/veil over visual field.
• Pain, redness, vision drop.

These suggest retinal tear or detachment—surgical emergency (within 24–48 hrs for macula-on).

Coping Tips

• Avoid bright backgrounds; use dark mode.
• Artificial tears for dryness.
• Ignore them; fixation on floaters increases perception.
• Follow post-op schedule (1 day, 1 week, 1 month).
