  • Place the lens on the index finger of the right hand and apply one drop of artificial tears.

  • Gently pull down the lower eyelid with the middle finger of the right hand.

  • Gently place the lens on the cornea and then remove the finger.

  • Release the lower eyelid and then release the upper eyelid. Repeat the same method for the other eye.

Lens Removal Method
Using the Eyelids

Looking into a mirror, open your eyes wide and place the index fingers of both hands near the eyelashes of the upper and lower eyelids.

Keep the fingers from directly touching the lens and take care not to turn the eyelids inside out.

Gently press the lower eyelid and push it upward.

When the lens naturally pops out due to the pressure, carefully remove it.

Using a Lens applicator(Lens plunger)

Hold the lens applicator(lens plunger) with the thumb and index finger of the right hand.

Open the eye wide and gently pull the upper and lower eyelids as when inserting the lens.

Align the lens applicator(lens plunger) with the pupil and attach it closely to the lens. Move the lens applicator(lens plunger) to remove the lens.

To detach the lens from the lens applicator(lens plunger), press the handle of the lens applicator(lens plunger).

Precautions When Removing the Lens
When removing LK Lens, first apply 1–2 drops of artificial tears to the eye and blink at least 10 times. Repeat this process at least 3 times, then move the eyes from side to side and up and down to allow sufficient tear circulation between the cornea and the lens before removing the lens.

If the lens is removed immediately without performing these steps, it may cause injury to the cornea and may also reduce the vision-correction effect.

Place the lens on the palm of your hand and apply 1–2 drops of LK Cleaner. Then, gently rub and clean the lens with the index finger of your right hand for at least 20 seconds without applying force.
