Can LASIK Cause Dry Eyes?

This question is critical because dry eye affects both comfort and visual quality. A patient can have a technically accurate laser treatment and still be unhappy if the tear film is unstable.

The tear film is the first optical surface of the eye. LASIK temporarily disrupts corneal nerves that help regulate tearing. When the tear film breaks up, vision can fluctuate and the eye can burn, sting, water, or feel gritty.

Dry eye symptoms include burning, stinging, foreign body sensation, redness, tearing, fluctuating vision, light sensitivity, contact lens intolerance, and eye fatigue with screens. LASIK can worsen these symptoms temporarily or, less commonly, longer term.

Risk factors include existing dry eye, meibomian gland dysfunction, blepharitis, autoimmune disease, certain medications, hormonal changes, high screen use, dry environments, contact lens intolerance, and prior ocular surface disease. The FDA’s LASIK quality-of-life project reported that some patients without dry eye before LASIK reported dry eye symptoms at three months.

Preoperative treatment may include lubricants, lid hygiene, warm compresses, prescription anti-inflammatory drops, oral omega-3 discussion where appropriate, punctal plugs, meibomian gland treatment, or delaying surgery. In some cases, PRK or another approach may be considered, but dryness remains relevant.

Severe eye pain, worsening redness, discharge, light sensitivity, or decreasing vision is not routine dry eye and should be evaluated. Severe preoperative dry eye can make LASIK inappropriate until controlled or may rule it out.

Evaluation includes tear breakup time, corneal staining, conjunctival staining, meibomian gland assessment, lid margin exam, tear quantity testing when appropriate, symptom review, medication review, and contact lens history. The surgeon should optimize the surface before final measurements.

Treatment includes preservative-free artificial tears, prescription dry eye medications, punctal plugs, lid hygiene, warm compresses, meibomian gland therapy, environmental changes, screen breaks, and delaying surgery. Post-LASIK dryness is managed aggressively to improve comfort and visual stability.

Do not hide dry eye symptoms to qualify for LASIK. Do not overuse redness-reliever drops. Do not stop prescribed drops early. Do not assume watery eyes mean you are not dry—reflex tearing can happen with dry eye.

Patients in Hanover, York, Adams County, South Central Pennsylvania, northern Maryland, and nearby Virginia should call May Eye Care Center when glasses or contact lenses are interfering with work, driving, sports, photography, surgery, outdoor activities, or quality of life. LASIK is elective, so the decision should be careful, measured, and based on a complete medical eye examination—not an advertisement or a discount offer. May Eye Care Center aims to be the MECCA of Eye Care: a trusted regional destination patients return to regularly for eye exams, surgical guidance, and straight answers about whether LASIK or another option truly fits their eyes.

Dry eye is not a side detail in LASIK. It is central to comfort, clarity, and patient satisfaction.
