ICL Lens Implantation: What to Check If You're Worried About Side Effects

Considering ICL lens implantation? Learn about potential side effects and crucial factors for choosing a reputable clinic to ensure a safe and effective procedure.

ICL Lens Implantation: What to Check If You're Worried About Side Effects

Hello, this is Gangnam Smile Eye Clinic😊💙

Recently, among those considering vision correction surgery,

many are being diagnosed with severe myopia, ultra-severe myopia, or thin corneas,

making LASIK or LASEK difficult.

Consequently, an increasing number of people are looking for clinics that excel in ICL lens implantation.

However, at the same time,

‘Is it really okay to put a lens inside my eye?’

‘Are there any side effects of ICL lens implantation?’

‘Will it be a good fit for my eyes?’

It's perfectly natural to have these concerns.

Today, along with discussing the side effects of ICL lens implantation,

we will outline the essential criteria for choosing a clinic that performs ICL lens implantation well.

Is ICL lens implantation truly safe?

EVO+ICL lens implantation is a vision correction surgery

whose safety and corrective efficacy have been thoroughly proven

through numerous domestic and international papers and clinical data.

Especially because it does not involve corneal ablation,

it can be a good alternative for those with:

✔Severe myopia

✔Thin corneas

✔Concerns about dry eyes

However, like all surgeries,

ICL lens implantation cannot completely rule out the possibility of side effects.

Commonly known side effects include:

✔Increased intraocular pressure (potential for glaucoma)

✔Potential for cataract development

✔Iris damage or pupil shape changes

However, the important point is that most of these issues

can be sufficiently predicted and prevented through precise pre-operative examinations.

Therefore, the key is ultimately to choose a clinic that excels in ICL lens implantation.

How to choose a clinic that performs ICL lens implantation well

ICL lens implantation is not just a simple lens insertion surgery;

it is a highly complex vision correction procedure that requires a precise understanding of the eye's structure

and personalized design.

Therefore, the choice of clinic is directly linked to the surgical outcome.

1. Does the clinic have university hospital-level precision diagnostic equipment?

A clinic that performs ICL lens implantation well will have a different approach

starting from the pre-operative examination.

Because it requires a very detailed analysis of intraocular structures such as

anterior chamber depth, corneal curvature, iris structure,

pupil size, and endothelial cell density,

high-resolution precision diagnostic equipment like:

✔Pentacam HR

✔B-SCAN

✔Corneal endothelial cell microscope

is essential.

If the examination is insufficient,

it is difficult to expect satisfactory results, no matter how good the lens is.

2. Does the clinic have extensive surgical experience with various eye conditions?

From severe myopia, large pupils, high intraocular pressure,

to a history of existing eye diseases,

eye conditions vary from person to person.

Therefore, a clinic that excels in ICL lens implantation

should have extensive experience with diverse cases.

During consultation, please make sure to check:

✔How accurately the medical staff explains your eye condition

✔Whether they logically explain why this surgery is suitable for you

3. Does the clinic offer 1:1 customized ICL lens sizing?

ICL is a surgery where lens size determines the outcome.

Even a slightly oversized lens can put a strain on the iris or crystalline lens.

A clinic that performs lens implantation well

comprehensively analyzes anterior chamber depth, iris diameter, and astigmatism axis

to custom-design a 1:1 lens tailored to the patient's eye.

If the explanation is 'everyone uses the same lens',

it's advisable to reconsider.

4. Is the post-operative management system systematic?

ICL lens implantation is not a procedure that ends with the surgery.

Even after surgery, the lens position, intraocular pressure changes, and crystalline lens condition

must be regularly checked.

A clinic that performs lens implantation well

has a systematic post-operative care program and a medical system

capable of rapid response in emergency situations.

For ICL lens implantation, consultation is the most important.

Lens implantation is certainly an attractive vision correction surgery

for those with severe myopia or for whom laser surgery is difficult,

but it requires an equally careful decision.

Therefore, a common characteristic of clinics that perform ICL lens implantation well

is that they are 'clinics that explain sufficiently' rather than 'clinics that recommend surgery'.

Make sure to check if personalized consultation is provided,

considering not only your eye condition but also:

Occupation (night shifts, long hours of monitor use, etc.)

Exercise habits

Lifestyle patterns

Desired vision level

If you can freely ask questions during the consultation process,

and the medical staff provides sufficient and sincere explanations,

that itself can be a trustworthy sign.

If you can freely ask questions during the consultation process

and the medical staff provides sufficient and sincere explanations,

that itself can be a trustworthy sign.

A careful choice leads to the best results.

While lens implantation is a surgery that can be reversed if necessary,

it is fundamentally a vision correction procedure

that remains in the eye for a long time.

Therefore, accurate information, sufficient consultation, and

choosing a clinic that performs ICL lens implantation well are paramount.

If you compare carefully

and make a decision after fully understanding,

you will surely be one step closer

to satisfactory vision correction results.
