LASIK Eye
Surgery in Korea

Definition

LASIK is a vision correction procedure that creates a thin corneal flap using a femtosecond laser, followed by precise corneal reshaping with an excimer laser to improve vision.
Because the corneal surface is not extensively removed, recovery is typically fast.

How the Procedure Works

Using advanced laser systems such as the VisuMax platform, a thin corneal flap is created and gently lifted. The underlying corneal tissue is then reshaped with an excimer laser to correct refractive errors. The flap is repositioned without the need for sutures, allowing for rapid visual recovery.

Who Can Benefit from LASIK

LASIK may be suitable for patients with sufficient corneal thickness who can safely undergo flap creation. It can correct a range of refractive errors, including myopia, astigmatism, and hyperopia.
Final eligibility is determined through a comprehensive eye examination based on individual eye condition and stability.

LASIK is a well-established vision correction procedure that offers a balance of safety,
efficiency, and long-term visual stability. The following benefits explain why LASIK remains a
widely chosen option for refractive surgery.

• 

  Fast Visual Recovery
  One of the key LASIK benefits is rapid visual recovery. Many patients experience noticeable
  improvement in vision as early as the next day, allowing a quick return to daily activities.

• 

  Reduced Post-Surgical Discomfort
  Because LASIK preserves most of the corneal surface, patients typically experience minimal
  discomfort after surgery. This contributes to a smoother recovery compared to some other
  vision correction procedures.

• 

  Short Procedure Time
  LASIK is a fast procedure, usually completed within about 10 minutes for both eyes. The
  short surgical time helps reduce patient anxiety and improves overall treatment efficiency.

• 

  Stable and Proven Visual Outcomes
  As a long-standing refractive surgery, LASIK has been clinically validated over many years.
  Patients can expect stable and predictable vision correction results when properly indicated.

• 

  Wide Range of Vision Correction
  LASIK can correct various refractive errors, including myopia, astigmatism, and hyperopia.
  This makes it a versatile option for many patients seeking vision correction in Korea.

• 

  Advanced Laser Technology
  Modern LASIK utilizes precise laser systems that enhance accuracy and predictability. This
  improves both surgical safety and the likelihood of achieving clear, high-quality vision.

• 

  Patients Seeking Fast Recovery and Quick Return to Daily Life

  LASIK involves minimal disruption to the corneal surface, allowing many patients to resume normal daily activities as early as the next day.

• 

  Patients Who Find Glasses or Contact Lenses Inconvenient

  By directly correcting vision, LASIK can reduce dependence on glasses or contact lenses and improve overall convenience in daily life.

• 

  Patients Who Want to Minimize Post-Surgical Discomfort

  Since LASIK does not require removal of the corneal surface, post-operative discomfort is generally mild compared to other procedures.

• 

  Patients with Relatively Stable Vision

  If your vision prescription has remained stable over time, LASIK may offer predictable and stable long-term results.

LASIK pre-surgery screening is an essential step that goes beyond simple vision testing. It evaluates overall eye condition, lifestyle factors, and patient expectations to determine the most suitable surgical approach for each individual.

• Corneal Condition

  Corneal thickness, shape, and structural strength
  Presence of any corneal abnormalities

• Ocular Health

  Assessment for conditions such as cataracts, glaucoma, or retinal disorders
  Evaluation of dry eye syndrome

• Occupation & Lifestyle

  Risk of external impact or eye injury
  Frequency of night vision use

• Priorities

  Desired recovery speed vs. long-term stability
  Sensitivity to discomfort

• Expectations

  Target vision outcomes
  Lifestyle patterns after surgery

LASIK is a precise vision correction process that uses advanced femtosecond and excimer laser technology to reshape the cornea while minimizing tissue damage, allowing for reduced discomfort and faster recovery.

• 

  STEP 1. Topical Anesthesia (Eye Drops)

  Anesthetic eye drops are applied to numb the eye, allowing the procedure to be performed comfortably without pain.

• 

  STEP 2. Creation of Corneal Flap (Femtosecond Laser)

  A femtosecond laser is used to create a thin and precise corneal flap. This step ensures uniformity and accuracy in preparing the cornea for correction.

• 

  STEP 3. Corneal Reshaping (Excimer Laser)

  An excimer laser reshapes the underlying corneal tissue based on the patient’s refractive error, correcting vision for conditions such as myopia and astigmatism.

• 

  STEP 4. Flap Repositioning and Natural Adhesion

  The corneal flap is gently repositioned to its original place, where it naturally adheres without the need for stitches, completing the procedure.

At EYE Plus Eye Clinic, LASIK is performed using advanced refractive technologies designed to enhance surgical precision, safety, and visual quality. Each system is carefully integrated to minimize intraoperative risks and improve long-term visual outcomes.

Corneal Stabilization Method Designed for Safety

A system that minimizes pressure on the eye during surgery helps prevent temporary vision blackout (loss of vision during the procedure), allowing patients to maintain visual awareness. It also reduces the risk of subconjunctival bleeding and protects conjunctival goblet cells, helping to prevent post-operative dry eye.

The greater the angle at the edge of the corneal flap, the more securely it adheres to the cornea. The VisuMax system creates a “bevel-in” side cut of up to 135°, allowing the flap to remain stable after surgery and better resist external impact. (Conventional LASIK: 90° / VisuMax LASIK: 135°)

A system that analyzes corneal aberrations and incorporates them into the treatment plan. By reflecting higher-order aberrations and visual axis alignment, it helps reduce glare and halos, particularly in low-light conditions.

When considering laser vision correction, understanding the differences between LASIK, LASEK (PRK), and SMILE is essential for choosing the most suitable procedure for your eyes and lifestyle.

• LASIK is one of the most widely performed procedures, known for its fast recovery time and quick visual improvement. By creating a thin corneal flap and reshaping the underlying tissue with a laser, most patients experience clearer vision within 24–48 hours. This makes LASIK a popular choice for those seeking rapid results and minimal downtime.
• LASEK (PRK), on the other hand, does not involve creating a corneal flap. Instead, it treats the surface of the cornea directly, which can be advantageous for patients with thinner corneas or those engaged in high-impact activities such as athletes or military personnel. While recovery typically takes longer—around 3 to 7 days—it offers a structurally safer option for certain eye conditions.
• SMILE represents a newer, third-generation approach to vision correction. Unlike LASIK, it is a flapless procedure that uses a small incision to remove a lenticule from within the cornea. This minimally invasive technique helps preserve corneal structure and may reduce the risk of dry eye symptoms. Recovery is also relatively fast, with many patients regaining functional vision within 24 hours.
