Can I get LASIK if I have dry eyes?

Dry eye is one of the most important factors in LASIK candidacy because the procedure temporarily worsens dry eye symptoms.

How LASIK Affects Dry Eyes

During LASIK, corneal nerves are cut when creating the flap. These nerves:

• Signal the brain to produce tears
• Take 3-6 months to fully regenerate
• May cause temporary dry eye in all patients

Pre-Existing Dry Eye Concerns

If you already have dry eyes, LASIK may:

• Significantly worsen symptoms
• Cause prolonged discomfort
• Affect visual quality
• Delay healing

Evaluation for Dry Eye

Your surgeon will assess:

• Tear film quality: Using special dyes
• Tear production: Schirmer's test
• Meibomian glands: Oil-producing glands in eyelids
• Symptoms: Burning, stinging, foreign body sensation

Treatment Before LASIK

If dry eye is detected, treatment may include:
1. Artificial tears (preservative-free)
2. Prescription drops (Restasis, Xiidra)
3. Punctal plugs to retain tears
4. Omega-3 supplements
5. Warm compresses and lid hygiene
6. IPL or other in-office treatments

Alternatives for Severe Dry Eye

• PRK: May cause less dry eye than LASIK
• SMILE: Preserves more corneal nerves
• ICL: No corneal nerve disruption

Many patients with mild to moderate dry eye can successfully have LASIK after proper preparation.
