What Happens During a LASIK Eye Procedure

Understanding the steps of a LASIK procedure can help patients feel more comfortable and prepared for surgery. While each clinic may have slight variations, most LASIK surgeries follow a standardized sequence designed for precision, safety, and minimal discomfort.

Step 1: Preoperative Preparation

Before the procedure, patients undergo:

• A thorough eye examination to measure corneal thickness, refractive error, and overall eye health
• Detailed discussion of vision goals, expectations, and potential risks
• Application of numbing eye drops to ensure the procedure is painless

Patients are also advised to remove contact lenses prior to surgery, as they can temporarily change corneal shape.

Step 2: Creating the Corneal Flap

Using a femtosecond laser, the surgeon creates a thin, precise flap on the cornea. This flap acts as a natural bandage and allows access to the underlying corneal tissue for reshaping.

Step 3: Reshaping the Cornea

An excimer laser is applied to the exposed corneal tissue to reshape it according to the patient’s prescription. This step corrects refractive errors such as myopia, hyperopia, and astigmatism.

Step 4: Repositioning the Flap

After the cornea is reshaped, the surgeon carefully repositions the corneal flap. The flap naturally adheres without the need for stitches, protecting the eye and promoting rapid healing.

Step 5: Immediate Postoperative Care

• Patients rest briefly while the flap stabilizes.
• Protective eye shields may be applied to prevent accidental rubbing.
• Prescribed eye drops help prevent infection and reduce inflammation.

Step 6: Follow-Up and Recovery

Follow-up visits are scheduled to monitor healing and ensure optimal visual outcomes. Most patients notice improved vision within 24–48 hours, though full stabilization may take several weeks.

Final Thoughts

LASIK is a precise, minimally invasive procedure designed for fast recovery and effective vision correction. By understanding each step, patients can feel more confident and prepared for their LASIK experience in Korean eye clinics.
