Yes, many surgeons recommend using preservative-free artificial tears, such as Systane, before LASIK to stabilise the tear film and optimise the corneal surface. A well-lubricated eye ensures more accurate pre-surgery measurements and smoother recovery. However, recommendations vary, so patients should follow their surgeon’s specific pre-op instructions.
Key Takeaways
- Systane stabilises the tear film, helping with pre-surgery measurements and reducing dryness after LASIK.
- Pre-surgery use helps to improve corneal surface hydration and ensures better laser accuracy.
- Systane is preferred due to its longer retention time, comfort, and preservative-free options.
- Patients should follow surgeon’s guidance on when and how to use Systane before LASIK.
- Using Systane regularly can lead to smoother recovery by alleviating dryness and irritation during healing.
Why Eye Hydration Matters Before LASIK
LASIK works by reshaping the cornea with a laser. For this process to succeed, the eye’s surface must be smooth and stable. If the tear film is patchy or uneven, the laser ablation may be less precise. This could affect both short-term comfort and long-term clarity. Systane is an artificial tear drop formulated to mimic the natural tear film. By restoring moisture, it reduces micro-irregularities on the cornea and creates the uniform surface surgeons need for accuracy.
How Systane Prepares the Eyes for Surgery
- Smooths the corneal surface – A hydrated cornea gives the laser a consistent surface to reshape.
- Reduces irritation risk – Moisture lowers friction on the ocular surface, which can help minimise inflammation triggers.
- Improves pre-surgery measurements – Surgeons rely on precise corneal maps to plan LASIK. Dry eyes distort those readings, but lubrication ensures more reliable scans.
- Stabilises tear film – A balanced tear film ensures surgical precision and lays the foundation for smoother recovery afterwards.
In some cases, doctors recommend starting Systane drops days or even weeks before surgery. This builds a baseline of hydration so that the eye responds well to the procedure.
Why Surgeons Choose Systane Over Generic Drops
Artificial tears come in many forms, but Systane has earned preference for a few reasons:
- Longer retention time: Certain Systane formulations (like Ultra or Balance) contain ingredients that increase retention compared to thinner, saline-based drops.
- Less blur after application: Some thicker gels blur vision temporarily; Systane is designed for comfort without clouding sight.
- Preservative-free options: For patients with sensitive eyes, Systane’s preservative-free vials lower irritation risk.
- Common use in LASIK care: Many LASIK centres recommend Systane before and after surgery because it supports tear film stability and patient comfort during healing.
Role of Systane in Preventing Dryness After LASIK
Dry eyes are the most common side effect after LASIK. The surgery temporarily affects corneal nerves that help regulate tear production. Using Systane beforehand helps stabilise the tear film and may reduce the severity of dryness during recovery. Patients often report that pre-surgery hydration makes the transition smoother because their eyes start from a healthier baseline. This can reduce the intensity of early symptoms like stinging, burning, or a gritty feeling.
Timing: When to Start Using Systane Before LASIK
The exact timing depends on the surgeon’s protocol, but common recommendations include:
- 1–2 weeks before surgery, if the patient already shows signs of mild dryness.
- Several days before surgery, for patients without major dryness but who want added stability.
- Day of surgery, under the surgeon’s guidance, to ensure the cornea is well hydrated before final measurements and treatment.
Consistency matters more than timing alone. Regular use builds a stable tear film, while sporadic drops may not give the same benefit.
How Systane Complements Other Pre-LASIK Preparations
Preparing for LASIK often involves more than hydration. Patients are asked to:
- Stop wearing contact lenses for several days or weeks, depending on lens type.
- Avoid eye makeup or lotions near the procedure date.
- Follow dietary or medication guidance, such as pausing certain supplements.
Systane fits naturally into this regimen, addressing the tear film side of preparation.
Practical Tips for Using Systane Before LASIK
- Use as directed: Many surgeons suggest frequent use (often 3–6 times daily), but dosing should be tailored to your dryness level and your doctor’s plan.
- Space out drops: Avoid clustering doses; spacing maintains consistent moisture.
- Keep single-use vials handy: Preservative-free options prevent irritation, especially for frequent use.
- Store properly: Keep drops sealed and avoid contamination of the tip.
- Combine with lifestyle care: Stay hydrated, reduce excessive screen time, and use a humidifier in dry environments.
What Patients Say About Using Systane Before LASIK
Many patients describe their eyes feeling “calmer” or “less gritty” going into surgery when they used Systane. They often notice faster comfort in the first few days after LASIK compared to friends or peers who did not use drops pre-operatively. While individual experiences vary, feedback consistently highlights that starting lubrication early makes recovery feel less harsh.
Can Systane Replace Medical Evaluation?
No. Artificial tears support surgery, but they cannot replace a professional exam. Surgeons use detailed tests to determine candidacy for LASIK. Systane helps prepare the eyes, but underlying conditions, such as severe dry eye, corneal disease, or uncontrolled allergies, require medical treatment beyond simple lubrication. Patients should always disclose any existing eye issues during their LASIK evaluation so the care plan can be tailored.
FAQs About Systane Use Before LASIK
Why do doctors recommend Systane before LASIK?
Because it stabilises the tear film, helps ensure accurate laser measurements, and lowers the risk of post-surgery dryness.
Can I use any artificial tears before LASIK instead of Systane?
Yes. Other preservative-free artificial tears work too, but Systane is often preferred for its comfort, longer effect, and preservative-free options.
How soon before LASIK should I start using Systane?
Most patients begin a few days to two weeks before surgery, based on their doctor’s advice.
Will Systane prevent all dryness after LASIK?
No. It lowers risk and eases symptoms, but some dryness is common for weeks or months.
Should I continue Systane after LASIK surgery?
Yes. Surgeons often recommend ongoing use during recovery to maintain comfort and protect healing.
