The Clear SMILE LASIK Procedure: A Comprehensive Guide 

It is a no-brainer that wearing contact lenses and glasses is a hassle. It’s a good thing there is Clear Smile LASIK, an advanced laser eye surgery that corrects several vision problems like astigmatism and myopia. It is a sought-after solution because of its convenience and practicality, providing patients with sharper, clearer vision without needing corrective lenses.

Eyeonce Eye Clinic Gangnam in Seoul, South Korea, offers a Clear Smile LASIK procedure specially performed by trained ophthalmologists who are experts in refractive eye surgeries using state-of-the-art laser technologies.

What is Clear Smile LASIK?

CLEAR stands for Corneal Lenticule Extraction for Advanced Refractive Correction. It combines the safety and efficacy of SMILE LASIK, using a small incision to perform the surgery, with the added benefit of “Advanced Refractive Correction” technology, taking the procedure to the next level.

It is a new and innovative method that offers several advantages, such as the following:

  • Improved vision – patients who have undergone this surgery have overcome several eye problems like nearsightedness, farsightedness, and astigmatism. They wake up each day with a clearer vision, saying goodbye to corrective eyewear!
  • Fast and painless– Clear Smile LASIK typically takes less than 15 minutes per eye. It is painless, with most patients experiencing only mild discomfort.
  • No downtime – Most patients can continue their everyday activities within 24-48 hours after the procedure. 
  • Long-lasting results – Clear Smile LASIK is a good investment as it is proven to give lasting results, with most patients experiencing improved visions even years after getting the procedure.
  • Safe and Effective – Patients do not have to worry about undergoing this eye surgery because it is performed by well-trained ophthalmologists who are experts in the field.
  • Convenience – Through Clear Smile LASIK, patients who lead active lifestyles have more freedom in work and environments where eyewear can be a hindrance.

What is the step-by-step process for the Clear Smile LASIK procedure?

The procedure usually takes about 3 to 4 minutes per eye and involves the following steps:

Pre-operative Preparations:

  • Your ophthalmologist will examine your eyes to ensure they suit the procedure.
  • During the procedure, you will be given numbing eye drops to keep your eyes numb and moist.
  • Discontinue using hard contact lenses at least two weeks before the surgery and soft lenses at least one week before the operation, as they affect the cornea’s shape.

During the Procedure:

  • First, your surgeon will place the docking system by ZIEMER FEMTO LDV Z8 on your cornea safely.
  • Using a femtosecond laser, your surgeon will create a disc-shaped piece of corneal tissue called a lenticule.
  • Then, the docking system will be lifted and your surgeon will make a small incision(2 mm).
  • After a small incision is made, your surgeon gently removes the lenticule through a small incision.
  • Lastly, your eyes will be rinsed using saline solution.

Post-operative Care:

  • Always use the prescribed eye drops to reduce inflammation and prevent infection.
  • Avoid rubbing or touching the eyes at least one month after the surgery.
  • Avoid closing your eyes too hard.
  • Always wash your hands before touching your face area.
  • Shower only a day after the surgery.
  • Never expose yourself to the sun without UV-blocking glasses three months after the surgery.
  • Wear protective eyewear, such as goggles, when doing physical activities such as exercising and jogging one week after the surgery.
  • Avoid skiing, swimming, or soaking in hot tubs for one week after the surgery.
  • Avoid applying eye makeup or using skincare products around the eyes.
  • Attend follow-up appointments with the surgeon to monitor progress and ensure proper healing.

The Clear Smile LASIK procedure is painless and may offer a slight burning sensation and discomfort immediately after the surgery. But do not worry because you will be given medications like eye drops to ease any discomfort and prevent infection.
