Revision ICL Surgery in Busan, Korea
For blurred vision after previous LASIK or LASEK, or concerns with an existing ICL. When the cornea is too thin for repeat laser surgery, an ICL can correct the remaining prescription without touching the cornea again.
Revision ICL, explained in one minute
Revision ICL uses an implantable collamer lens to correct vision that has drifted after previous laser surgery, or reviews and adjusts an existing ICL. Because the lens sits inside the eye, it adds correction without removing more corneal tissue.
After LASIK or LASEK, myopia can return or the cornea can change shape. If the remaining corneal thickness is below the safety limit, a second laser treatment may risk haze, epithelial ingrowth or corneal weakening (ectasia). An ICL avoids those risks.
For patients with an existing ICL, BGSS evaluates the lens vault, position and rotation and discusses whether repositioning, exchange or removal is needed.
Cause first, surgery last
Re-correction is only planned once your eyes are stable.
Find the cause
Detailed tests identify why vision changed: regression, corneal shape change, dry eye or lens position.
Treat underlying issues
Dry eye management or specialist referral comes first where needed.
Correct when stable
Once your eyes are stable, the ICL is sized to your eye and implanted, or an existing ICL is adjusted.
Six advantages over repeat laser
From BGSS’s official re-correction guidance.
No change to the cornea
The remaining cornea is left untouched.
Minimal regression
Correction comes from the lens, not further reshaping.
No epithelial ingrowth
No flap is lifted again.
Minimal haze
No new surface ablation.
Less dry eye
Corneal nerves are not cut again.
Very low ectasia risk
Avoids further corneal weakening.
Who revision ICL suits
Revision may be considered if you:
- Had LASIK or LASEK and your nearsightedness has returned
- Have a thin or flat central cornea after previous surgery
- Have an irregular corneal surface with dry eye
- Have an existing ICL with vault, rotation or vision concerns
- Have enough space inside the eye and a healthy endothelium
Bring your previous surgery records if you have them. Eligibility is confirmed after examination.

Revision ICL in Busan: frequently asked questions
What is revision ICL?
Revision ICL uses an implantable lens to correct vision after previous LASIK or LASEK, or reviews and adjusts an existing ICL, without removing more corneal tissue.
Why not repeat LASIK or LASEK?
If the remaining cornea is thin, repeat laser surgery may risk haze, epithelial ingrowth, keratoconus-like weakening or loss of vision. An ICL avoids further corneal thinning.
What results has BGSS seen?
In a BGSS case series of 10 patients who had LASIK or LASEK elsewhere (myopia −0.50 to −3.50 D before ICL), all reached 20/20 to 20/16 after ICL.
Can an existing ICL be exchanged or removed?
Yes. After examining the vault, position and rotation, your doctor discusses whether repositioning, exchange or removal is appropriate.
What should I bring?
Your previous surgery records, glasses prescription and any recent eye test results.
Can international patients have revision surgery in Busan?
Yes. Coordinators support you in English and Chinese and help plan any extra visits.
