Shinsegae Ortho-K Lenses

Clearer tomorrows — vision correction that starts while you sleep

Ortho-K lenses are high-oxygen permeable lenses
that gently reshape the central cornea
overnight to correct
your daytime vision.

A safe, non-surgical alternative for vision
correction without any operation.

Why Ortho-K lenses help

  • Glasses-free daily life

    Glasses-free daily life

    Remove the lens in the morning and enjoy

    clear vision all day long.

  • Slowing childhood myopia

    Slowing childhood myopia

    Slows myopia progression by 40-60% vs glasses,

    preventing severe high myopia.

  • Safe non-surgical method

    Safe non-surgical

    No corneal ablation — safe,

    fully reversible if you stop wearing.

How Ortho-K lenses work

01·03
STEP 1

Wear the custom lens before bed

A custom-shaped, high-oxygen lens
gently reshapes the central cornea while you sleep.

STEP 2

Vision corrected while sleeping

The corneal surface is softly reshaped overnight
for an effect similar to LASIK.

STEP 3

Remove the lens in the morning

The corrected corneal shape persists, giving you
clear daytime vision without glasses.

Detail makes the difference —
Shinsegae Multi-Curve Design

Precision design tailored to each patient's corneal curvature
delivers optimal vision correction.

  • Alignment CurveBoosts fit and prevents lens decentration
  • Peripheral CurveHealthy tear flow for safe long-term wear

STEP 2

The custom lens gently presses
the epithelium to reshape cells.

Shinsegae myopia medication

One drop a day — myopia-control eye drops

Low-dose atropine eye drops regulate eye growth
and slow myopia progression — an effective
non-surgical treatment.

Inhibits axial growth icon

Inhibits axial growth

Myopia develops as the eye's axial length grows.
Atropine regulates scleral growth in the eye wall,
preventing further axial elongation.

Slows myopia progression icon

Slows myopia progression

Clinical results show medication can reduce
myopia progression by about 50%
compared with no treatment.
