Can You Get LASIK If You Have Dry Eyes?

Why does dry eye matter before LASIK?

LASIK creates a corneal flap and uses a laser to reshape the tissue underneath. Both steps can temporarily reduce corneal nerve density, which means the eye's signal to produce tears is dampened for months after surgery. If your tear film is already fragile, that disruption can make dryness noticeably worse — causing blur, discomfort, and slower visual recovery 1Ref 1Amescua G, Ahmad S, Cheung AY, Choi DS, Jhanji V, Lin A, Mian SI, Rhee MK, Viriya ET, Mah FS, Varu DM; American Academy of Ophthalmology Preferred Practice Pattern Cornea/External Disease Panel (2024).Dry Eye Syndrome Preferred Practice Pattern.Pre-existing dry eye as a relative contraindication for laser refractive surgery; comprehensive dry eye evaluation before LASIK including Schirmer's test, tear breakup time, meibomian gland assessment, and surface staining; post-LASIK dryness from corneal nerve disruption.

The AAO Dry Eye Syndrome Preferred Practice Pattern identifies pre-existing dry eye as a relative contraindication for laser refractive surgery, and recommends thorough evaluation and treatment before proceeding 1Ref 1Amescua G, Ahmad S, Cheung AY, Choi DS, Jhanji V, Lin A, Mian SI, Rhee MK, Viriya ET, Mah FS, Varu DM; American Academy of Ophthalmology Preferred Practice Pattern Cornea/External Disease Panel (2024).Dry Eye Syndrome Preferred Practice Pattern.Pre-existing dry eye as a relative contraindication for laser refractive surgery; comprehensive dry eye evaluation before LASIK including Schirmer's test, tear breakup time, meibomian gland assessment, and surface staining; post-LASIK dryness from corneal nerve disruption. The AAO Refractive Errors Preferred Practice Pattern also lists dry eye assessment as part of mandatory pre-operative candidacy screening 2Ref 2Jacobs DS, Afshari NA, Bishop RJ, Keenan JD, Lee J, Shen TT, Vitale S; American Academy of Ophthalmology Preferred Practice Pattern Refractive Management/Intervention Panel (2023).Refractive Errors Preferred Practice Pattern.LASIK candidacy criteria including dry eye screening; alternative procedures (PRK, SMILE) for patients with dry eye or anatomical risk factors; ophthalmologist role in pre-operative assessment.

What does a pre-LASIK dry eye evaluation look like?

Your ophthalmologist will assess several things:

• Symptom questionnaires — standardized tools to measure how much dry eye affects your daily life
• Tear volume tests (Schirmer's test) — a small strip of paper placed at the eyelid margin measures how much moisture your eyes produce
• Tear breakup time — how long it takes for the tear film to develop dry spots after a blink
• Corneal surface staining — special dyes reveal areas of damage on the front of the eye
• Meibomian gland evaluation — these lid glands produce the oily layer of tears; blockage is a common dry eye driver 1Ref 1Amescua G, Ahmad S, Cheung AY, Choi DS, Jhanji V, Lin A, Mian SI, Rhee MK, Viriya ET, Mah FS, Varu DM; American Academy of Ophthalmology Preferred Practice Pattern Cornea/External Disease Panel (2024).Dry Eye Syndrome Preferred Practice Pattern.Pre-existing dry eye as a relative contraindication for laser refractive surgery; comprehensive dry eye evaluation before LASIK including Schirmer's test, tear breakup time, meibomian gland assessment, and surface staining; post-LASIK dryness from corneal nerve disruption

Mild dry eye that responds well to artificial tears and lid hygiene is often manageable before surgery. Moderate-to-severe dry eye, or dry eye that has not responded to treatment, is more likely to lead a surgeon to recommend against LASIK or to suggest waiting 2Ref 2Jacobs DS, Afshari NA, Bishop RJ, Keenan JD, Lee J, Shen TT, Vitale S; American Academy of Ophthalmology Preferred Practice Pattern Refractive Management/Intervention Panel (2023).Refractive Errors Preferred Practice Pattern.LASIK candidacy criteria including dry eye screening; alternative procedures (PRK, SMILE) for patients with dry eye or anatomical risk factors; ophthalmologist role in pre-operative assessment.

Can dry eye be treated so LASIK becomes an option?

In many cases, yes. Surgeons commonly ask patients to complete a course of dry eye therapy — which might include preservative-free artificial tears, warm compresses and lid massage for meibomian gland dysfunction, omega-3 supplementation, or prescription anti-inflammatory drops — and then re-evaluate. If the tear film stabilizes significantly, the risk-benefit calculation can shift.

Some patients may also do better with alternative laser procedures that do not create a corneal flap, such as PRK (photorefractive keratectomy) or SMILE, which preserve more corneal nerves at the surface. PRK is longer to recover from visually, but some surgeons prefer it for people with borderline dry eye. SMILE incises a smaller arc than a LASIK flap and has been shown to produce better corneal sensitivity and tear film outcomes in the first post-operative months 3Ref 3Tamimi A, Sheikhzadeh F, Ezabadi SG, Islampanah M, Parhiz P, Fathabadi A, et al. (2023).Post-LASIK dry eye disease: A comprehensive review of management and current treatment options.Dry eye is the most common complication after LASIK; pre-existing dry eye is the primary risk factor; SMILE produces better post-operative corneal sensitivity and tear film outcomes vs LASIK; treatment options for post-LASIK dry eye including cyclosporine, autologous serum, and punctal plugs. The right choice depends on your individual corneal anatomy and the severity of your symptoms 2Ref 2Jacobs DS, Afshari NA, Bishop RJ, Keenan JD, Lee J, Shen TT, Vitale S; American Academy of Ophthalmology Preferred Practice Pattern Refractive Management/Intervention Panel (2023).Refractive Errors Preferred Practice Pattern.LASIK candidacy criteria including dry eye screening; alternative procedures (PRK, SMILE) for patients with dry eye or anatomical risk factors; ophthalmologist role in pre-operative assessment.

What happens to dry eye after LASIK?

Post-LASIK dryness is common and usually peaks in the first few weeks to months. A 2023 comprehensive review found that dry eye disease is 'the most common complication after LASIK,' with pre-existing dryness identified as the single most significant risk factor 3Ref 3Tamimi A, Sheikhzadeh F, Ezabadi SG, Islampanah M, Parhiz P, Fathabadi A, et al. (2023).Post-LASIK dry eye disease: A comprehensive review of management and current treatment options.Dry eye is the most common complication after LASIK; pre-existing dry eye is the primary risk factor; SMILE produces better post-operative corneal sensitivity and tear film outcomes vs LASIK; treatment options for post-LASIK dry eye including cyclosporine, autologous serum, and punctal plugs. Most patients with mild pre-surgical dryness see their symptoms resolve within three to six months as corneal nerves regenerate.

However, a subset of patients — particularly those with unrecognized moderate dry eye before surgery — experience persistent symptoms that require ongoing management 1Ref 1Amescua G, Ahmad S, Cheung AY, Choi DS, Jhanji V, Lin A, Mian SI, Rhee MK, Viriya ET, Mah FS, Varu DM; American Academy of Ophthalmology Preferred Practice Pattern Cornea/External Disease Panel (2024).Dry Eye Syndrome Preferred Practice Pattern.Pre-existing dry eye as a relative contraindication for laser refractive surgery; comprehensive dry eye evaluation before LASIK including Schirmer's test, tear breakup time, meibomian gland assessment, and surface staining; post-LASIK dryness from corneal nerve disruption3Ref 3Tamimi A, Sheikhzadeh F, Ezabadi SG, Islampanah M, Parhiz P, Fathabadi A, et al. (2023).Post-LASIK dry eye disease: A comprehensive review of management and current treatment options.Dry eye is the most common complication after LASIK; pre-existing dry eye is the primary risk factor; SMILE produces better post-operative corneal sensitivity and tear film outcomes vs LASIK; treatment options for post-LASIK dry eye including cyclosporine, autologous serum, and punctal plugs. Treatment options for post-LASIK dry eye include preservative-free artificial tears, cyclosporine A, diquafosol, autologous serum eye drops, and punctal plugs for more severe cases.

For this reason, disclosure is important. If you use artificial tears regularly, have symptoms like grittiness, redness, light sensitivity, or end-of-day blur, tell your surgeon before any testing begins. These details help calibrate the evaluation.

Who should you see for this evaluation?

A comprehensive pre-LASIK evaluation is performed by an ophthalmologist — a physician who specializes in medical and surgical eye care. The evaluation is typically done at the refractive surgery practice where you are considering treatment. If you already have a diagnosed dry eye condition being managed by an ophthalmologist or optometrist, share those records with the surgical team.

The goal of the pre-operative assessment is not to disqualify candidates but to identify the right procedure and timing for each individual. Many people with mild dry eye proceed successfully to LASIK after appropriate preparation 2Ref 2Jacobs DS, Afshari NA, Bishop RJ, Keenan JD, Lee J, Shen TT, Vitale S; American Academy of Ophthalmology Preferred Practice Pattern Refractive Management/Intervention Panel (2023).Refractive Errors Preferred Practice Pattern.LASIK candidacy criteria including dry eye screening; alternative procedures (PRK, SMILE) for patients with dry eye or anatomical risk factors; ophthalmologist role in pre-operative assessment.
