Introduction

When it comes to vision correction, today’s patients are not just looking for immediate results; they are seeking a solution that offers long-term stability, safety, and precision. In Korea, where visual health is highly valued and the demand for refractive surgery continues to rise, SMILE surgery stands out as a modern, minimally invasive alternative to traditional LASIK. For those seeking an even more robust, durable outcome, the integration of Avedro KXL (corneal cross-linking) technology into SMILE has become a game-changer.

At Gangnam Joeunnun Vision Clinic, we don’t just offer vision correction; we provide personalized, state-of-the-art treatments designed to preserve both your vision and eye health for years to come. This in-depth guide is tailored for first-time patients, walking you through the Avedro KXL SMILE process — from consultation to post-op recovery — and answering common questions along the way.

What Is the Avedro KXL System, and Why Is It Used in SMILE?

Before we walk you through the steps of the treatment, it’s important to first understand the Avedro KXL system and how it works in conjunction with SMILE.

What Is Corneal Cross-Linking?

Corneal cross-linking (CXL) is a procedure designed to strengthen the collagen fibers within the cornea by creating additional cross-links between them. The Avedro KXL system accelerates this process using UV light in combination with riboflavin (vitamin B2). The result? A stronger, more stable cornea that resists the kind of thinning and deformation that might occur over time — particularly important for individuals with thinner corneas or who engage in high-impact activities that could lead to corneal stress.

• Why it matters for SMILE:
  SMILE, which stands for Small Incision Lenticule Extraction, reshapes the cornea to correct refractive errors such as myopia (nearsightedness) and astigmatism. However, this process does involve removing a small portion of the cornea’s tissue. This can sometimes compromise the overall stability of the cornea. By incorporating Avedro’s KXL technology, we enhance the cornea’s structural integrity, which can result in fewer post-op complications and faster recovery times.

Imagine your cornea as a delicate, finely crafted structure. SMILE reshapes it for better vision, while Avedro KXL reinforces its strength, ensuring it holds up for years.

Step-by-Step: What to Expect from Your Avedro KXL SMILE Experience

At Gangnam Joeunnun Vision Clinic, our goal is to ensure every patient feels comfortable and confident throughout the entire process. Whether you're a first-time surgery patient or an experienced individual looking for a modern solution, here’s a breakdown of each stage of the Avedro KXL SMILE journey.

Comprehensive Pre-Surgical Evaluation: Laying the Foundation for Success

Your journey starts long before you step into the operating room. Pre-surgical assessments are critical for identifying the best treatment plan for your eyes. This involves:

Detailed Eye Examination

Using cutting-edge technology like the ZEISS Pentacam and Anterion Anterior Segment OCT, we perform a series of tests to map your eye’s shape and condition. These include:

• Pachymetry: Measuring corneal thickness to assess suitability for SMILE and KXL. Patients with thinner corneas may benefit most from cross-linking.
• Corneal topography: Mapping the curvature of your cornea to detect irregularities and ensure you have a stable, symmetrical shape.
• Tear film analysis: Identifying any dryness or irritation issues that might impact healing.
• Assessment of ocular health: We check for underlying conditions such as glaucoma, retinal diseases, or cataracts that could affect the surgery.

This holistic approach ensures your SMILE treatment is safe and tailored to your specific needs. What many people overlook is the importance of having an accurate understanding of their eye health before surgery. At Gangnam Joeunnun Vision Clinic, we ensure that no stone is left unturned to give you the best outcome.

Pre-Surgery Instructions: Preparing Your Eyes (and Mind)

Once we confirm you’re a candidate for SMILE with Avedro KXL, we will provide detailed pre-operative instructions, which generally include:

• Stop wearing contact lenses: You’ll be asked to stop wearing soft contact lenses for at least 1–2 weeks and hard lenses for about a month prior to surgery. This is to ensure the cornea returns to its natural shape.
• Avoid makeup and lotions: On the day of surgery, avoid wearing eye makeup, lotions, or creams around the eyes to minimize the risk of infection.
• Take prescribed eye drops: We may prescribe antibiotics and anti-inflammatory eye drops to use leading up to the surgery to reduce the risk of infection and inflammation.
• Arrangements for transportation: Since the surgery is done with topical anesthetics and you may feel a bit groggy afterward, arrange for a family member or friend to drive you home.

This time before surgery is not just about preparing physically, but also about calming any nerves. If you’re wondering whether vision correction surgery is right for you, remember — it’s completely normal to have some apprehension. Our team is here to guide you every step of the way.

The Day of Surgery: What Happens in the Operating Room?

Step 1: Anesthetic Drops & Initial Prep

We’ll start by numbing your eyes with topical anesthetic drops, ensuring you feel no pain during the procedure. Once your eyes are numb, we place a small device to gently keep your eyelids open.

Step 2: SMILE Surgery – Shaping Your Cornea

The SMILE procedure begins with the use of the ZEISS VisuMax femtosecond laser to create a small, precise lenticule (tissue disc) inside the cornea. This lenticule is then carefully extracted through a tiny 2–4 mm incision. The remaining corneal tissue is reshaped to correct your refractive error.

The beauty of SMILE lies in its minimally invasive nature. Unlike LASIK, no flap is created, which means fewer risks and a faster recovery.

Step 3: Cross-Linking with Avedro KXL

Once the SMILE procedure is complete, we immediately move on to accelerated corneal cross-linking. Here’s how it works:

• Riboflavin (vitamin B2) is applied to your cornea, and we wait for it to be absorbed for about 60–90 seconds.
• We then use the Avedro KXL system, which delivers a precise UV-A light to the cornea. This light activates the riboflavin, causing the collagen fibers to bond and strengthen.

This is a quick, painless procedure that helps reinforce the cornea’s structural integrity, providing long-term support for the vision changes made during SMILE surgery.

Immediate Post-Surgery: Relax, Rest, and Reassure

After surgery, we’ll escort you to a comfortable recovery room where you’ll rest for 20–30 minutes. During this time:

• We’ll apply post-operative eye drops to keep your eyes lubricated and prevent infection.

• You’ll be asked to wear protective sunglasses to shield your eyes from bright light and potential irritation.

• Our medical staff will check your visual clarity and ensure you’re feeling okay before heading home.

Recovery at Home: What to Expect in the First 24–48 Hours

The first few days after surgery are vital to ensure your healing process begins smoothly. Here’s a breakdown of what you can expect:

Common Experiences Post-Surgery

• Mild irritation: You may feel a gritty sensation or mild pressure in your eyes.
• Light sensitivity: Many patients experience heightened sensitivity to light, which should gradually subside.
• Blurred vision: Your vision may fluctuate during the first 24–48 hours, with clarity improving steadily.

We’ll give you specific instructions for your aftercare, which include using lubricating drops to keep your eyes comfortable and preventing any strain or rubbing.

Essential Post-Op Care Instructions

• Use prescribed eye drops as directed to reduce inflammation and prevent infection.
• Avoid strenuous activity: Rest is key during the first 48 hours, including refraining from swimming or intense physical exertion.
• Protect your eyes: Wear your protective glasses as instructed, particularly when outdoors or in bright environments.

Follow-Up Care: Monitoring Progress and Adjusting Treatment

• Day 1: We check on initial healing and your comfort level.
• Week 1: A more detailed check-up of your corneal stability and visual clarity.
• 1 Month: Final follow-up to ensure you’ve reached optimal vision and the cross-linking process has integrated successfully.

We’ll also provide any necessary adjustments to your care routine, ensuring you’re on track for the best possible outcome.

Who Is a Good Candidate for Avedro KXL SMILE?

While SMILE is suitable for many patients with nearsightedness or astigmatism, adding Avedro KXL is especially beneficial for:

• Thinner corneas: If your corneal thickness is borderline, the added cross-linking ensures strength without compromising visual clarity.
• Active individuals: Those involved in sports or jobs that put their eyes at risk from trauma can benefit from the extra stability KXL provides.
• Younger patients: If you’re seeking early intervention for refractive errors but want to preserve the long-term health of your cornea, Avedro KXL is a good option.

If you’re unsure whether this combined treatment is right for you, a consultation at Gangnam Joeunnun Vision Clinic is the first step to understanding your unique needs.
