If you wear contact lenses and regularly experience dryness, burning, redness, grittiness, or discomfort, you may wonder whether SMILE Pro is a suitable alternative. In some patients, SMILE Pro may be an option because it is a flapless vision-correction procedure, but contact-lens irritation alone does not determine eligibility. Your surgeon needs to evaluate the health of your cornea, tear film, prescription, and overall eye condition before recommending treatment.
Can Contact Lens Users Have SMILE Pro?
Yes, many contact lens users may be candidates for SMILE Pro, but chronic irritation should be evaluated first.
Contact lenses themselves can contribute to discomfort, dryness, redness, and other ocular-surface problems. If symptoms are persistent, removing the lenses and getting an eye examination is important rather than assuming the irritation is simply a normal part of lens wear.
SMILE Pro may be considered when:
- Your prescription is stable.
- Your cornea has adequate thickness and a suitable shape.
- Your eye surface is reasonably healthy.
- Dry eye or irritation is mild and manageable.
- There is no active eye infection or significant corneal disease.
- Your ophthalmologist confirms that you are an appropriate candidate.
Why Might SMILE Pro Be Considered?
SMILE uses a small corneal incision rather than creating the larger corneal flap used in LASIK. However, this does not mean that SMILE Pro is completely free from dry-eye risk.
Potential advantages may include:
1. Flapless procedure
SMILE removes a small lenticule through a small incision instead of creating a LASIK-style flap.
2. Potentially less disruption to corneal nerves
The smaller incision may preserve more corneal tissue and nerves than some flap-based procedures. This can be relevant when discussing postoperative comfort and dry-eye symptoms.
3. Less dependence on contact lenses
If your irritation is primarily related to contact-lens wear, correcting the underlying refractive error may allow you to stop wearing lenses. However, SMILE itself is not a treatment for dry-eye disease.
What If You Already Have Dry Eyes?
This is one of the most important parts of the evaluation.
Having occasional or mild contact-lens discomfort does not automatically rule out SMILE Pro. However, significant or uncontrolled dry eye may need treatment before refractive surgery is considered.
Your ophthalmologist may assess:
| Evaluation | Why It Matters |
| Tear-film quality | Checks how well your tears protect the eye surface |
| Tear production | Helps assess whether your eyes produce enough tears |
| Corneal examination | Identifies corneal abnormalities or surface damage |
| Corneal topography/tomography | Checks corneal shape and suitability for surgery |
| Prescription stability | Confirms that your vision has remained relatively stable |
| Contact-lens history | Helps identify whether lenses are contributing to irritation |
A proper examination is particularly important because dry-eye symptoms and objective signs do not always match perfectly. FDA guidance for dry-eye studies also recognizes the importance of assessing both symptoms and objective signs.
Mild Irritation vs Severe Dry Eye
| Situation | What It May Mean for SMILE Pro |
| Occasional dryness after wearing contacts | May still be compatible with treatment after evaluation |
| Mild irritation or lens discomfort | Usually requires assessment but does not automatically exclude surgery |
| Frequent redness or burning | Needs evaluation before proceeding |
| Persistent dry-eye symptoms | Dry eye should be assessed and managed |
| Severe or uncontrolled dry eye | Surgery may need to be postponed until the condition is controlled |
| Active infection or significant eye inflammation | Refractive surgery should generally be deferred until the problem is addressed |
The key point: being uncomfortable in contact lenses does not automatically mean you are unsuitable for SMILE Pro—but it also should not be assumed that SMILE Pro will solve the irritation.
What Should Contact Lens Users Do Before SMILE Pro?
Before your consultation:
- Tell your surgeon how long you have worn contact lenses.
- Explain how many hours per day you wear them.
- Mention burning, redness, itching, dryness, or gritty sensations.
- Bring your current prescription if available.
- Follow your clinic's instructions about stopping contact-lens wear before measurements.
- Do not restart lenses if your eyes become significantly red or painful without speaking with an eye-care professional.
Contact-lens users with eye irritation should remove the lenses and seek professional advice, particularly when symptoms include pain, redness, discharge, or vision changes.
SMILE Pro vs Contact Lenses
Can SMILE Pro Reduce Contact Lens Irritation?
It may help indirectly if your irritation is caused by contact-lens wear, because successful vision correction can reduce or eliminate the need for lenses.
But this distinction is important:
SMILE Pro corrects refractive error; it does not directly treat chronic dry-eye disease.
If your symptoms are caused by an underlying dry-eye condition, allergy, blepharitis, meibomian gland dysfunction, corneal problem, or another eye condition, that issue may continue after surgery and needs separate management.

Frequently Asked Questions
Can contact lens users undergo SMILE Pro?
Yes. Contact-lens use alone does not prevent you from having SMILE Pro. Your surgeon will assess your prescription, cornea, tear film, and overall eye health before determining eligibility.
Is SMILE Pro better than LASIK for dry eyes?
There is no single procedure that is best for everyone with dry eyes. SMILE and LASIK have different surgical techniques and potential side effects, so the decision should be based on your individual eye-surface health and corneal measurements
Can SMILE Pro cure chronic dry eyes?
No. SMILE Pro is a refractive procedure designed to correct vision, not a treatment for chronic dry-eye disease.
Can I have SMILE Pro if contact lenses make my eyes dry?
Possibly. Mild lens-related dryness does not automatically exclude you, but your dry-eye status should be evaluated before surgery.
Should I stop wearing contact lenses before SMILE Pro?
Usually, patients are asked to stop wearing lenses for a period before their preoperative measurements. The exact duration depends on the type of lens and your surgeon's protocol.
Can I stop wearing contact lenses permanently after SMILE Pro?
If the procedure successfully corrects your refractive error, you may no longer need contact lenses for distance vision. However, some patients may still need glasses or additional vision correction.
Is SMILE Pro safe for people with severe dry eye?
Severe or uncontrolled dry eye requires careful evaluation and management. Surgery may need to be postponed until the ocular surface is adequately treated. Refractive surgery can itself cause or worsen dry-eye symptoms in some patients.
Is Laser Eye Surgery Painful?
No—laser eye surgery like LASIK is not painful because numbing eye drops prevent pain during the procedure, and any mild discomfort afterward is usually temporary and manageable.
Do Contact Lenses Expire?

Can I have LASIK Surgery Twice?
A second LASIK is possible but depends on corneal health, vision stability, and other factors. Consulting an eye specialist is the best way to decide.
