SMILE Pro reduces dry eye risks compared to SMILE by minimising corneal nerve disruption, shortening laser exposure, and preserving the eye’s natural tear film regulation.
Thanks to advanced technology and a more refined surgical approach, SMILE Pro offers a safer, more comfortable vision correction option, especially for those prone to dry eyes.
If you’re considering laser eye surgery and worried about dry eye symptoms, understanding how SMILE Pro addresses this concern can help you make a confident, informed choice. Here’s an in-depth look at how SMILE Pro lowers dry eye risks and why it’s quickly becoming the preferred option for both surgeons and patients.
The Link Between Laser Eye Surgery and Dry Eye
Dry eye frequently occurs as a side effect following laser vision correction. It occurs when the procedure disrupts corneal nerves that help regulate tear production and sensation. LASIK, which involves creating a corneal flap, tends to affect more nerves and is associated with a higher risk of post-operative dry eye, especially in the early healing phase. SMILE, though less invasive and using a smaller incision, can still cause temporary dry eye in some patients while the nerves regenerate.
How does SMILE Pro improve on SMILE for Dry Eye Prevention?
Faster Laser Speed Means Less Stress on the Eye
SMILE Pro uses the latest VisuMax 800 femtosecond laser, completing the laser scanning in under 10 seconds per eye compared to SMILE’s 22 seconds. This ultra-fast treatment means:
- The eye is exposed to the laser for a much shorter period.
- There’s less overall stress, suction-loss risk, and inflammation on the corneal surface.
- Recovery is quicker, which can help reduce the duration and severity of dry eye symptoms.
Minimal Corneal Nerve Disruption
Both SMILE and SMILE Pro are flapless procedures, but SMILE Pro’s even smaller incision and more precise laser application further minimise nerve damage. The result:
- More corneal nerves, blink, and tear reflexes are preserved, supporting healthier tear production.
- Tear film regulation is less disturbed, which is crucial for preventing dry eye after surgery.
Enhanced Tear Film Regulation
SMILE Pro preserves most of the corneal epithelium and Bowman’s layer, which helps maintain corneal structure and may contribute to a more stable tear film compared to procedures that disrupt these layers more significantly. By maintaining these layers, the eye’s natural ability to regulate moisture is optimised, making SMILE Pro especially suitable for patients with a history of dry eye or contact lens intolerance.
Precision and Customisation with Advanced Software
The VisuMax 800’s advanced software allows for:
- Finer adjustments to the incision size and lenticule shape.
- Personalised treatment that matches each patient’s unique corneal structure, reducing unnecessary tissue trauma.
- Improved accuracy in astigmatism correction, which can also reduce post-op irritation and dryness.
SMILE Pro vs. SMILE: Key Differences for Dry Eye Risk
| Feature | SMILE | SMILE Pro |
| Laser Duration (Per Eye) | 22 seconds | <10 seconds |
| Incision Size | Small | Even smaller, more precise |
| Corneal Nerve Disruption | Minimal | Even less |
| Tear Film Impact | Mild | Minimal |
| Healing Time | Fast | Faster |
| Suitability for Dry Eye Sufferers | Good | Excellent |
Why Faster Laser Speed Matters for Dry Eye?
A shorter laser time means the cornea is less exposed to environmental factors and less likely to dry out during surgery. This reduces the risk of inflammation, speeds up recovery, and helps maintain a more stable tear film in the critical days after surgery.
SMILE Pro and Tear Film Preservation
SMILE Pro’s keyhole approach and advanced laser precision mean less disruption to the corneal surface and nerves that control tear production. By maintaining the integrity of these structures, SMILE Pro patients are less likely to experience the burning, grittiness, and fluctuating vision that come with dry eye.
Patient Comfort and Experience
Patients who undergo SMILE Pro often report:
- Less dryness and irritation post-surgery.
- Faster return to comfortable, clear vision.
- Less need for artificial tears or other dry eye treatments after the procedure.
For those who have struggled with dry eyes from contact lens use or ageing, SMILE Pro is often recommended as a safer, more comfortable alternative to traditional laser procedures.
What the Research Says?
Recent studies and surgeon reports highlight that:
- SMILE Pro’s reduced laser time and refined technique lead to fewer dry eye complaints compared to both SMILE and LASIK.
- Patients with pre-existing dry eye or those at higher risk (such as older adults or long-term contact lens wearers) benefit most from SMILE Pro’s minimally invasive design.
- Preservation of corneal nerves and tear film regulation are the main reasons for these improved outcomes.
Tips to Further Reduce Dry Eye Risk After SMILE Pro
- Follow all post-op instructions and use prescribed lubricating drops.
- Avoid dusty, windy, or air-conditioned environments for the first week.
- Stay hydrated and blink regularly, especially during screen time.
- Wear sunglasses outdoors to protect your eyes from the sun and wind.
Why Surgeons Prefer SMILE Pro for Dry Eye Prevention?
Surgeons increasingly recommend SMILE Pro because:
- It offers a safer, faster, and more comfortable experience for patients at risk of dry eye.
- FDA approval and positive clinical outcomes have boosted confidence in its safety and effectiveness.
- Its advanced technology allows for personalised, minimally invasive treatment with less trauma to the eye.
Your Next Steps for Comfortable, Clear Vision
SMILE Pro stands out as the safest laser vision correction option for reducing dry eye risks, thanks to its advanced laser speed, minimal nerve disruption, and superior tear film preservation.
If you’re concerned about dry eye or have struggled with irritation after other eye procedures, talk to your ophthalmologist about SMILE Pro. With its patient-friendly design and proven comfort, you can look forward to clearer vision and healthier, happier eyes.
Frequently Asked Questions About SMILE Pro and Dry Eye
Is SMILE Pro suitable for people with existing dry eye?
Yes. SMILE Pro’s minimal nerve disruption and tear film preservation make it an excellent choice for those already prone to dry eye or with a history of contact lens intolerance.
How soon does dryness resolve after SMILE Pro?
Most patients notice less dryness and a faster return to normal tear production compared to other laser surgeries. Symptoms, if present, are usually mild and temporary.
Do I still need artificial tears after SMILE Pro?
Some patients may use lubricating drops for a few days or weeks, but the need is generally less than after LASIK or even SMILE.
Can SMILE Pro prevent all dry eye symptoms?
No procedure can guarantee zero risk, but SMILE Pro significantly lowers the chances and severity of dry eye compared to older techniques.
