Introduction: The Joy and Surprise After LASIK

One of the most emotional moments in our clinic is watching a patient open their eyes after LASIK and realize they can see the clock across the room without glasses for the first time in years. The joy is palpable—freedom from glasses or contact lenses often feels like stepping into a new life.

At Jryn Eye Clinic in Busanjin-gu, Busan, we hear this question frequently. The answer is both reassuring and nuanced: yes, dryness is common after LASIK—but there are important details to know about what’s normal, what’s not, and how to manage it.

This article will walk you through why dry eye occurs after LASIK, what to expect in recovery, and how we approach treatment here at our clinic. Our goal is to help you feel informed, reassured, and confident about your healing journey.

Why Dry Eyes Happen After LASIK

LASIK is a highly advanced procedure, but it still involves delicate interaction with the eye’s natural structures. During LASIK, a thin flap is created in the cornea, and a laser reshapes the tissue beneath to correct vision.

Here’s the key point: the cornea is rich with tiny nerves that signal your eyes to produce tears. When these nerves are temporarily cut or disrupted during surgery, the communication between your cornea and tear glands weakens. As a result, your eyes may not produce enough tears—or the tears may evaporate too quickly—leading to dryness.

We often explain this to patients using a simple analogy: it’s like trimming a tree. For a short while, the branches may not grow as fully, but once the roots regenerate, the tree becomes lush again. Similarly, as the corneal nerves heal (usually over months), the eyes gradually regain their normal tear regulation.

What “Normal” Post-LASIK Dryness Looks Like

It’s important to know what is expected versus what might signal a complication.

• Timeline: Most patients feel some dryness in the first 3–6 months after LASIK. Symptoms typically peak in the first few weeks, then gradually improve.
• Sensations: Grittiness, sandy feeling, mild redness, or blurry vision that clears after blinking.
• Triggers: Air-conditioned rooms, heated interiors in winter, long computer use, and even wearing a mask (which directs airflow upward into the eyes) can worsen dryness.

In Korea, where long work hours and heavy screen use are part of daily life, these symptoms may feel more noticeable. But in the majority of cases, they steadily fade with proper care.

When Dryness Is More Than Just Temporary

Not every case of dryness after LASIK is “normal.” Certain signs suggest the need for professional evaluation:

• Severe discomfort that does not improve with artificial tears
• Persistent dryness beyond a year after surgery
• Sharp pain, stinging, or burning that interrupts daily activities
• Sudden changes in vision unrelated to blinking
• Underlying conditions such as pre-existing severe dry eye, autoimmune disease, or meibomian gland dysfunction

In these cases, the dryness may not simply be part of the healing process—it may be a sign of chronic dry eye syndrome or another underlying condition that requires targeted treatment.

Risk Factors: Who Is More Likely to Experience Dry Eye After LASIK?

Not all patients experience the same degree of dryness. Some groups are more vulnerable:

• Contact lens overusers (especially those with corneal stress from years of wear)
• Patients in their 40s and 50s, when natural tear production begins to decline
• Women after menopause, due to hormonal changes affecting tear stability
• Patients with high myopia, who often require deeper corneal reshaping
• Individuals with existing meibomian gland dysfunction, where oil glands in the eyelids don’t function optimally

LASIK vs. SMILE: Which Is Gentler for Dry Eyes?

A question we often hear is: “Would SMILE have been better for dryness?”

SMILE (Small Incision Lenticule Extraction) is a newer procedure that requires only a tiny incision, rather than creating a corneal flap. Because of this, fewer corneal nerves are disrupted, and studies suggest SMILE patients may experience less postoperative dryness compared to LASIK.

However, the difference is not dramatic for every patient. The right choice depends on many factors, including corneal shape, lifestyle, and visual goals. At our clinic, we guide patients toward the procedure best suited to both their vision correction and long-term comfort—sometimes that’s LASIK, sometimes SMILE, and sometimes EVO ICL, which doesn’t involve reshaping the cornea at all.

Managing Dry Eyes After LASIK: Our Approach at Jryn Eye Clinic

We believe healing is not just about clear vision, but comfortable vision. Here’s how we address dryness in our patients:

Pre-Surgery Prevention

• Identifying patients with pre-existing dry eye

• Treating eyelid inflammation or meibomian gland dysfunction before surgery

• Recommending alternatives like EVO ICL for those at high risk

Immediate Post-Surgery Care

• Prescribing medicated eye drops (anti-inflammatory and lubricating)

• Scheduling close follow-ups to track healing progress

• Encouraging preservative-free artificial tears to reduce irritation

Advanced Therapies for Persistent Cases

For patients whose dryness doesn’t resolve naturally, we offer:

• Punctal plugs, which block tear drainage and keep natural moisture on the eye longer
• Thermal gland expression, to restore meibomian gland function
• Prescription drops that improve tear production and reduce inflammation
• Specialty lenses in rare cases where surface protection is needed

Every treatment plan is personalized, because no two eyes are exactly alike.

What You Can Do at Home

Patients often ask, “What can I do myself to help my eyes recover?” While professional care is essential, daily habits play a huge role:

• Use preservative-free artificial tears several times a day

• Take screen breaks—practice the 20-20-20 rule (every 20 minutes, look 20 feet away for 20 seconds)

• Increase humidity in your home or office, especially in winter

• Wear wraparound sunglasses outdoors to protect against wind and sun

• Stay hydrated and maintain a balanced diet with omega-3 fatty acids, which support tear quality

These small adjustments often make recovery more comfortable.

Patient Stories: Real-Life Experiences

One of our patients, a 29-year-old office worker in Seomyeon, described feeling as if “sand was trapped” in her eyes after her LASIK surgery. She was worried something had gone wrong. After a detailed check-up, we reassured her it was temporary dryness, prescribed lubricating drops, and within four months her symptoms had completely resolved.

Another patient, a 47-year-old teacher, experienced persistent dryness even 9 months after LASIK. Because she had mild meibomian gland dysfunction before surgery, we added thermal gland therapy and punctal plugs. Within weeks, her comfort improved dramatically.

Conclusion: Clear Vision, Comfortable Eyes

The most important thing is not to ignore symptoms. Dryness may feel like a minor inconvenience, but untreated dry eye can affect vision quality and long-term eye health.

At Jryn Eye Clinic in Busanjin-gu, we see dryness not as a complication to endure, but as part of the healing process that can be managed with precision and care. Our mission is to give every patient not only clear vision, but also comfort and confidence in their eyes for years to come.
