Will I have dry eyes after LASIK?

Dry eye is the most common side effect after LASIK, but it's usually temporary and manageable.

Why LASIK Causes Dry Eye

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

• Signal your brain to produce tears
• Take 3-6 months to fully regenerate
• Temporarily reduce tear production

Timeline of Dry Eye

Week 1

• Most noticeable dry eye symptoms
• Frequent artificial tear use (every 1-2 hours)
• Normal part of healing

Weeks 2-4

• Symptoms begin improving
• Tear use decreasing
• Still use drops regularly

Months 1-3

• Significant improvement
• May only need drops few times daily
• Some days may not need drops

Months 3-6

• Most patients back to normal
• Nerves regenerating
• Occasional dry eye may persist
