Managing Dry Eye Before and After LASIK

Dry eye is common around LASIK—and manageable. Preparing your tear film improves comfort and visual quality.

Why dryness matters

The cornea and tear film work together to create a smooth optical surface. If tears evaporate too fast or glands underperform, vision can blur and fluctuate. LASIK temporarily affects corneal nerves involved in tear feedback, so planning ahead helps.

Before surgery: build a healthier tear film

• Screen for dryness: Tell your surgeon about burning, fluctuating vision, or contact lens intolerance.
• Hydration & environment: Use humidifiers and take frequent screen breaks (20‑20‑20 rule).
• Artificial tears: Start preservative‑free lubricants if advised.
• Lid hygiene: Gentle warm compresses and lid cleaning can improve meibomian gland function.
• Treat contributors: Allergies, blepharitis, or demodex may need targeted care before surgery.

After surgery: comfort and consistency

• Frequent artificial tears: Keep the cornea well‑lubricated, especially in the first 1–3 months.
• Medicated drops: Use anti‑inflammatory drops exactly as directed.
• Omega‑3s/diet: Discuss with your doctor; evidence is mixed but may help some patients.
• Contact lens break: Avoid lenses until cleared; rely on tears and sunglasses for comfort.

When dryness is more than mild

• Punctal plugs: Reduce tear drainage to keep natural tears on the eye longer.
• Prescription drops: Your doctor may add medications for chronic dry eye.
• In‑office options: Gland treatments and light‑based therapies can be considered in select cases.

Reducing flare‑ups

• Avoid smoke, wind, and very dry air when possible.
• Blink fully and often during screen time.
• Wear wraparound sunglasses outdoors early in recovery.

Bottom line

Plan for dryness as part of LASIK. Proactive care makes a noticeable difference in comfort and the sharpness of your results.
