Dry eye after cataract surgery: causes, symptoms and duration

Dry eye after cataract surgery: why it happens and how long it lasts

Cataract surgery is a very safe procedure, but during the postoperative period some patients may experience dryness, irritation or fluctuating vision.

This is not a complication, but a temporary response of the eye. Patients with dry eye syndrome may notice these symptoms more clearly.

What causes it?

• Reduced corneal sensitivity
• Altered tear reflex
• Unstable tear film

Common symptoms

Foreign body sensation

Mild burning or irritation

Fluctuating vision during the day

Increased need for artificial tears

How long does it last?

• Begins in the first days after surgery
• More noticeable during the first 2–4 weeks
• Improves progressively

Practical insight (my experience)

This transient dry eye can be more noticeable in patients with trifocal lenses.
