ICL (Implantable Collamer Lens) surgery has gained popularity in recent years as a method of vision correction and is attracting attention as an alternative to LASIK.
ICL corrects vision by inserting a special lens inside the eye. Unlike LASIK, it does not involve removing corneal tissue, and is therefore considered suitable for patients who wish to reduce surgical risk or who have thin corneas.
As the number of people considering ICL surgery increases, many wonder: what age is appropriate for the procedure?
■ Suitable Age for ICL Surgery
In most cases, patients aged 20 or older may undergo ICL surgery.
This is because stable vision is required. During the late teenage years and early twenties, vision may still fluctuate, particularly in patients with high myopia, and waiting for stability is recommended.
For this reason, the mid‑20s to around the 40s is considered an appropriate age range.
■ Early 20s to Early 30s
Vision is generally stable and eye health is often good in this age group, making it an ideal time to consider ICL surgery.
Patients may enjoy a life less dependent on glasses or contact lenses, which is particularly beneficial for active lifestyles.
■ 40s to 50s
After age 40, age‑related eye changes begin and may affect surgical outcomes.
Presbyopia progresses, and glasses for near vision may be required.
However, for patients with strong refractive errors, correcting distance vision with ICL may reduce overall visual strain in daily life.
■ Age 50 and Above
The risk of cataracts increases after age 50, and in some cases ICL implantation may not be suitable.
In such situations, alternatives such as multifocal intraocular lens implantation combined with cataract surgery may be considered.
If ICL is still desired, it is important to discuss cataract risk thoroughly with a physician.
■ Summary
ICL surgery is generally suitable for patients from the mid‑20s to around their 40s with stable vision, but candidacy varies individually.
A decision should be made after careful consultation with a specialist, considering vision status, lifestyle, and potential future changes in eyesight.
